[Prior Art] One of various displays is a liquid crystal display. In order to facilitate the viewing of a display device such as a wide viewing angle and a high definition of a liquid crystal display, the surface of the liquid crystal display, that is, the surface reflection of the surface of the polarizing plate cannot be ignored. In other words, the deterioration of the visibility caused by the reflection of the surface of the satellite navigation positioning system with a high frequency of outdoor use by the monitor or the camera monitor becomes remarkable. Therefore, in the polarizing plate of these machines, the antireflection film is indispensable, and for a liquid crystal display having a high frequency of outdoor use, a polarizing plate to which an antiglare treatment is applied is practically used.

Under the layer, an excellent anti-glare anti-reflection film with an excellent adhesion after the endurance test can be formed. Further, it is preferable that the antiglare layer of the antiglare antireflection film and the low refractive index layer have a high refractive index layer interposed therebetween. The description of the low refractive index layer continues. The refractive index of the low refractive index layer is lower than that of the transparent film substrate of the support, and is 1.1 at a wavelength of 5 50 nm at 23 ° C'. 30~1.

Wherein, the average particle size of the colloidal cerium oxide is less than 1 of the average particle diameter of the hollow cerium oxide microparticles.  1 to 2 0 times better. Further, the low refractive index layer may contain two or more kinds of hollow cerium oxide fine particles having different average particle diameters. The description will be continued for hollow ceria particles (hereinafter simply referred to as hollow particles) which are porous or void inside. The hollow fine particles are (1) composite particles formed on a porous particle and a coating layer on the surface of the porous particle, or (2) having voids therein, and the contents are filled with a solvent, a gas or a porous substance. Empty particles. Further, the hollow particles are particles having voids inside, and the voids are surrounded by the particle walls. The inside of the cavity is filled with contents such as a solvent, a gas, or a porous substance at the time of preparation. The average particle diameter of the hollow fine particles is 5 to 20 nm, preferably 1 to 70 nm. The particle size of the hollow fine particles is preferably a monodispersion with a variation coefficient of from 1 to 40%. The average particle diameter of the hollow ceria particles can be determined by an electron micrograph by a scanning electron microscope (SEM) or the like. The measurement is carried out by using a particle size distribution meter such as a dynamic astigmatism-31 - 200904636 method or a static astigmatism method. The average particle diameter of the hollow fine particles to be used may be appropriately selected in accordance with the transparent coating thickness of the formed low refractive index layer, and the film thickness of the transparent envelope is preferably 3/2 to 1/10, preferably 2/3~ 1/10. Among them, the hollow fine particles are preferably formed in a state of being dispersed in an appropriate medium due to the formation of a low refractive index layer.

The thickness of the coating layer of the composite particles or the particle wall thickness of the void particles is 1 to 40 nm, preferably 1 to 20 nm, more preferably 2 to 15 nm. In the case of the composite particles, when the thickness of the coating layer is less than 1 nm, the particles may not be completely coated, and the coating liquid component easily enters the inside of the composite particles, and the internal porosity is reduced, so that a sufficient effect of lowering the refractive index cannot be obtained. When the thickness of the coating layer exceeds 20 nm, the coating liquid component does not enter the inside, and the porosity (pore volume) of the composite particles is lowered, and a sufficient effect of lowering the refractive index may not be obtained. Further, in the case of the void particles, when the thickness of the particle wall is less than 1 urn, the particle shape may not be maintained, and even if the thickness exceeds 20 nm, the sufficient effect of lowering the refractive index cannot be achieved. It is preferred that the coating layer of the composite particles or the particle walls of the void particles have ruthenium dioxide as a main component. Further, components other than cerium oxide may be contained, and specific examples thereof include Al2〇3, B2〇3, Ti〇2, Zr〇2, Sn〇2, Ce〇2, P203, Sb2〇3, and Mo〇3. Zn〇2, W03, etc. Examples of the porous particles constituting the composite particles include those obtained by cerium oxide, inorganic compounds other than cerium oxide and cerium oxide, and those of CaF2, NaF, NaAlF6, and MgF-32-200904636. Among them, a porous particle composed of a composite oxide of an inorganic compound other than cerium oxide and cerium oxide is preferred. Examples of the inorganic compound other than cerium oxide include one or more of Al2〇3, B2〇3, TiO2, Zr02, Sn02, Ce02 'P2O3 'Sb2〇3 'M0O3 ' Zn02 'W03, and the like. In such a porous particle, cerium oxide is represented by S i O 2 , and the molar ratio of the inorganic compound other than cerium oxide in terms of oxide (ΜΟΧ) is 0. 0001~1. 0, preferably 0. 001~0. The scope of 3. It is difficult to obtain a porous particle having a molar ratio of MOx/SiO 2 of less than 0. In the case of 000 1 , even if the pore volume is small, the particles having a lower refractive index cannot be obtained. Further, if the molar ratio of the porous particles to MOx/Si 02 exceeds 1. 0, the ratio of cerium oxide becomes small, so the pore volume becomes large, and it is difficult to obtain a refractive index lower. The pore volume of such a porous particle is 0. 1~1. 5 ml / g, preferably 0. 2~1. A range of 5 ml/g. The pore volume is not up to 〇. When lml/g, particles with a sufficiently reduced refractive index cannot be obtained, if it exceeds 1. At 5 ml/g, the strength of the fine particles is lowered, and the strength of the resulting envelope is reduced. Further, the pore volume of such a porous particle can be obtained by a mercury intrusion method. Further, examples of the content of the void particles include a solvent, a gas, a porous substance, and the like which are used in particle preparation. The solvent may contain void particles, unreacted materials of the particle precursor used for preparation, and a catalyst to be used. Further, examples of the porous material include those exemplified as the porous particles. These contents may be a single component or a mixture of plural components. As a method for producing the hollow fine particles, for example, a method of preparing composite oxide colloidal particles according to paragraph numbers [〇01〇] to [〇〇33] of JP-A-33-200904636 No. 7-133105 can be employed. Specific composite particles When inorganic compounds other than cerium oxide or cerium oxide are formed, hollow fine particles can be produced by the following first steps to third steps. First Step: Preparation of Porous Particle Precursor In the first step, an alkali aqueous solution of a raw material of an inorganic compound other than dioxins and a raw material other than dioxins is prepared in advance, or an inorganic substance other than a dioxane raw material and cerium oxide is prepared. The mixed aqueous solution of the compound raw material is mixed with the aqueous solution as the target composite oxide in an aqueous solution of pH 10 or higher, and the pore-preserving precursor is gradually added while stirring. As the raw material of cerium oxide, an alkali metal, ammonium or organic alkali acid salt can be used. As the ceric acid salt of an alkali metal, sodium citrate (water glass potassium citrate) can be used. Examples of the organic base include amines such as a fourth-order ammonium salt such as a tetraethylammonium salt, an ethanolamine such as diethanolamine or triethanolamine. The ammonium citrate organic base citrate also contains an alkaline solution of ammonia, a fourth-order ammonium compound, an amine compound, etc. in the citric acid solution. Further, as a raw material of an inorganic compound other than cerium oxide, the alkalinity may be used. Specific examples of the inorganic compound to be dissolved include an oxidizing acid of an element selected from the group consisting of Al, B, Ti, Sn, Ce, P, Sb, Mo, Zn, and W, an alkali metal salt or an alkaline earth metal salt of the acid, and ammonium. Salt, fourth grade ammonium salt. The body is sodium aluminate, sodium tetraborate, ammonium zirconium carbonate, potassium citrate, sodium citrate citrate, sodium molybdate, cerium ammonium nitrate, sodium citrate.矽, 配,多出矽) or, single salt or hydrogen oxygen use Zr, oxidation more, aluminum-34- 200904636 Although the addition of these aqueous solutions, the pH of the mixed aqueous solution will change, the pH操作 Controlling the operation within the specified range is not particularly necessary. The aqueous solution ultimately determines its pH based on the type of inorganic oxide and its mixing ratio. The rate of addition of the aqueous solution at this time is not particularly limited. Further, in the production of the composite oxide particles, the dispersion of the seed particles can be used as a starting material. The particles are not particularly limited, and inorganic oxides such as S i Ο 2 ' A12 Ο 3 , TiO 2 or ZrO 2 or fine particles of the composite oxides can be used. Generally, these sols can be used. Further, the porous particle precursor dispersion obtained by the above production method can also be used as a seed particle dispersion. When the seed particle dispersion liquid is used, the pH of the seed particle dispersion liquid is adjusted to 1 Torr or more, and the aqueous solution of the above compound is added to the aqueous base solution with stirring in an aqueous alkali solution. At this time, it is not necessary to carry out the dispersion p Η control. When such a seed particle is used, it is easy to control the particle size of the prepared porous particle, and a uniform particle size can be obtained. The above-mentioned ceria raw material and inorganic compound raw material have a high solubility in alkali. However, when the two are mixed in a large pH region of the solubility, the solubility of oxidized acid ions such as citrate ions and aluminate ions is lowered, and these complexes are precipitated to grow into fine particles or particles which are precipitated on the seed particles. Child growth. Therefore, it is not necessary to perform p Η control as in the past method when the fine particles are precipitated and grown. The composite ratio of the inorganic compound other than cerium oxide and cerium oxide in the first step is converted to an oxide (ΜΟχ) for the inorganic compound of cerium oxide, and the molar ratio of MOx/Si 〇 2 is 〇_〇5. ~2·0, preferably 0. 2 -35- 200904636 ~2. Within the range of 0. Within this range, the smaller the ratio of silica sand, the larger the pore volume of the porous particles. However, Morbi even exceeds 2. 0, the pore volume of the porous particles hardly increases. On the other hand, Moerby has not reached 0. At 05 o'clock, the pore volume will become smaller. When modulating the cavity particles, the molar ratio of M0x/Si02 is 0. 25~2. Within the range of 0 is preferred. Step 2: Removal of inorganic compound other than cerium oxide from porous particles In the second step, the porous particle precursor obtained in the first step is an inorganic compound other than cerium oxide (an element other than cerium and oxygen). At least a portion is selectively removed. As a specific removal method, the inorganic compound in the porous particle precursor is dissolved or removed by using a citric acid or an organic acid, or is contacted with a cation exchange resin, and then subjected to ion exchange removal. Further, the porous particle precursor system obtained in the first step is a mesh structure particle in which an element of an inorganic compound and an inorganic compound are bonded via oxygen. By thus removing the inorganic compound (the element other than cerium and oxygen) from the porous particle precursor, a porous particle having a large pore volume in the porous body can be obtained. Further, by removing the amount of the inorganic oxide (the element other than cerium and oxygen) from the porous particle precursor, the void particles can be prepared. Further, before removing the inorganic compound other than cerium oxide from the porous particle precursor, the fluorine-containing content obtained by subjecting the alkali metal salt containing cerium oxide to alkali removal is added to the porous particle precursor dispersion obtained in the first step. It is preferred that the tannic acid solution or the hydrolyzable organic sand compound of the alkyl group-substituted decane compound forms a cerium oxide protective film. The thickness of the ruthenium dioxide protective film is from 0.5 to 40 nm, preferably 0. The thickness of 5~15nm can be used. Further, even if the -36-200904636 cerium oxide protective film is formed, the protective film of this step is porous, and the inorganic compound other than the above-mentioned cerium oxide can be removed from the porous precursor of the porous precursor. By forming such a cerium oxide protective film, the inorganic compound other than the above-mentioned cerium oxide can be removed from the porous particle precursor while maintaining the particle shape. Further, when the ceria coating layer described later is formed, the pores of the porous particles are not blocked by the coating layer, so that the pore volume can be formed without forming a cerium oxide coating layer which will be described later. Further, when the amount of the inorganic compound to be removed is small, the particles are not destroyed, and it is not necessary to form a protective film. Further, when the void particles are prepared, it is preferable to form the ceria protective film. When the void particles are prepared, when the inorganic compound is removed, a precursor of the void particles formed by the cerium oxide protective film, the solvent in the cerium oxide protective film, and the undissolved porous solid component can be obtained. When a coating layer to be described later is formed in the body, the formed coating layer becomes a particle wall to form void particles. The amount of the ceria source to be added in order to form the above-mentioned ceria protective film is preferably less in the range in which the particle shape can be maintained.

Alkoxydecane is shown. Particularly, tetraalkoxy decane such as tetramethoxy decane, tetraethoxy decane or tetraisopropoxy decane which is substituted by fluorine is preferably used. As a method of addition, a solution of a small amount of a base or an acid as a catalyst is added to a mixed solution of alkoxysilane, pure water, and an alcohol, and added to a dispersion of porous particles, which will be alkoxydecane. a solution of a small amount of a base or an acid as a catalyst added to a mixed solution of pure water and an alcohol, added to a dispersion of porous particles, and a citric acid polymer formed by hydrolysis of alkoxydecane is attached to the inorganic On the surface of the oxide particles. In this case, alkoxydecane, an alcohol, and a catalyst may be simultaneously added to the dispersion. As the base catalyst, ammonia, an alkali metal hydroxide or an amine can be used. Further, as the acid catalyst, various inorganic acids and organic acids can be used. When the dispersion medium of the porous particle precursor is water alone or when the ratio of water to the organic solvent is high, a ruthenium acid solution can be used to form a ruthenium dioxide protective film. When a citric acid solution is used, a predetermined amount of citric acid solution is added to the dispersion, and a base is added to adhere the citric acid solution to the surface of the porous particle. Further, a cerium oxide protective film can be produced by using a citric acid solution together with the above alkoxy decane. Step 3: Formation of a ruthenium dioxide coating layer In the third step, in the porous particle dispersion (the void particle precursor dispersion in the case of void particles) prepared in the second step, by adding a fluorine-substituted alkane a hydrolyzable organic sand compound or a citric acid solution of a decane compound, and the surface of the particle is coated with a polymer such as a hydrolyzable organic hydrazine compound or a sulphuric acid solution to form a cerium oxide coating layer. -38 - 200904636 The citric acid solution is obtained by subjecting an aqueous solution of an alkali metal ruthenate such as water glass to an alkali-removed low-polymer aqueous solution of citric acid. The organic cerium compound or the ceric acid solution used for forming the coating layer may be added in an amount sufficient to sufficiently coat the surface of the colloidal particles, and the thickness of the cerium oxide coating layer finally obtained may be 1 to 40 ηηη, preferably The amount of 1 to 2 Onm is added to the dispersion of the porous particles (the void particles are actually hollow particle precursors). When the cerium oxide protective film is formed, the total thickness of the cerium oxide protective film and the cerium oxide coating layer is 1 to 40 nm, and preferably an organic cerium compound or a ceric acid solution is added in an amount of 1 to 20 nm. The dispersion forming the particles of the coating layer is heat-treated by adhesion. In the case of the porous particles, the porous oxidized coating on the surface of the porous particles is densified to obtain a dispersion of the composite particles in which the porous particles are coated with the cerium oxide coating. Further, in the case of a void particle precursor, the formed coating layer is densified to become a void particle wall, and a dispersion liquid having voids in which a cavity is filled with a solvent, a gas or a porous solid component is obtained. The heat treatment temperature at this time is only to the extent that the pores of the ceria coating layer can be blocked, and is not particularly limited, and is preferably in the range of 80 to 300 °C. When the heat treatment temperature is less than 80 °C, the fine pores of the ceria coating layer may be completely blocked, and the densification may not be performed, and the treatment time must be long. When the heat treatment temperature exceeds 300 ° C for a long period of time, it becomes a dense particle, and the effect of lowering the refractive index cannot be obtained. The refractive index of the inorganic fine particles thus obtained is lower from -39 to 200904636 when it is less than 1 _ 4 2 . The inorganic fine particles can be piled up to maintain the porosity inside the porous particles, but the inside is hollow, so that the refractive index is lowered. In addition, as hollow fine particles, hollow fine particles which are covalently bonded to a polymer having a hydrocarbon main chain on the surface are excellent in adhesion, abrasion resistance, and visibility after a severe durability test. It is better. Continuing, the description will be made of hollow fine particles in which a polymer having a hydrocarbon main chain is easily covalently bonded. The polymer having a hydrocarbon main chain is a direct covalent bond, or a cerium oxide on the surface of the hollow cerium oxide microparticles and a polymer having a hydrocarbon main chain, and a coupling agent is interposed between the cerium oxide and the binder. In combination with the valence bond, it can also be said that the binding agent and the polymer are covalently bonded. It is preferred to use a coupling agent as a binder. The hollow fine particles in which the polymer having a hydrocarbon main chain is easily covalently bonded can be surface-treated with the surface of the hollow cerium oxide particles by treating the surface of the hollow cerium oxide particles with an untreated or a coupling agent or the like. a method of reacting a polymer having a functional group capable of forming a covalent bond, grafting the polymer on the surface of the hollow ceria particle, or (2) treating the surface of the hollow ceria particle with an untreated or coupling agent In the state of being treated, a monomer is polymerized from the surface of the hollow ceria microparticles to grow a polymer chain, and the surface is grafted. As a specific production method, the method described in JP-A-2006-257308 can be used. In the above production method, a method of polymerizing a monomer from the surface of the hollow silica sand fine particles to grow a polymer chain and grafting the surface thereof is preferable from the viewpoint of increasing the surface modification ratio. After the hollow ceria particles are subjected to a surface treatment of -40 to 200904636 by a coupling agent containing a functional group having a polymerization initiation energy or a chain shifting energy, the polymerization of the monomer to grow the polymer chain is better. a surface treatment agent (optionally using an alkoxy metal compound (for example, a titanium coupling agent, a decane oxime as an oxy metal compound) of the functional group hollow cerium oxide microparticles having a polymerization initiation energy or a chain shifting energy; The general formula (an alkane coupling agent is preferred.

In the present invention, the fluorine-based surfactant has a fluorine content ratio of %, preferably 〇. 1 to 1% by mass. The fluorine-based boundary may be used alone or in combination of two or more. The description of the polyoxyalkylene surfactant is continued. The polyoxyalkylene surfactant used in the present invention is a type of organic group of a ruthenium atom, and is largely classified into a pure polythene polysiloxane. Among them, the pure polyoxyalkylene oil is a combination of a methyl group and a substituent. The modified polyoxyalkylene oil is a component of secondary derivatization. On the one hand, the reactivity of oxyalkyl oils is classified. The above is summarized as follows. Polyoxane oil 1 . Pure polyoxyalkylene oil 1 -1.

Modified Polyoxane Oil A modified polyoxane oil produced by introducing a wide variety of organic groups into dimethylpolysiloxane oil. 2 -1 · Non-reactive polyoxyalkylene oil: alkyl/aralkyl modified polyoxyalkylene, such as alkyl, alkyl/aralkyl, alkyl/polyether, polyether, higher fatty acid ester substitution The oil is a polyether modified polyoxyalkylene oil in which a part of the methyl group of the dimethyl polysiloxane oil is replaced by a long chain or a phenyl group, and the hydrophilicity is The polyoxyalkylene group is introduced into a polyoxyalkylene-based polymer surfactant of hydrophobic dimethyl polyoxyalkylene. The higher fatty acid modified polyoxyalkylene oil is a polyoxyalkylene oil in which a part of a methyl group of a dimethylpolysiloxane oil is substituted with a higher fatty acid ester. The amine-modified polyoxyalkylene oil is a polyoxyalkylene oil having a structure in which a methyl group of a polyoxyalkylene oil is partially substituted with an aminoalkyl group. The epoxy group-modified polyoxyalkylene oil is a polyoxyalkylene oil having a structure in which a part of a methyl group of a polysiloxane oil is substituted with an alkyl group having an epoxy group. The carboxyl group-modified or alcohol-modified polyoxyalkylene oil is a polyoxan oil having a structure in which a part of a methyl group of a polyoxyalkylene oil is substituted with an alkyl group having a carboxyl group or a hydroxyl group. 2_2. Reactive polyoxyalkylene oil: amine group, epoxy group, carboxyl group, alcohol substitution, etc. -51 - 200904636 wherein polyether modified polysiloxane oil can be added. The number average molecular weight of the polyether modified polyoxyalkane oil is, for example, 1,000 to 100,000, preferably 2,000 to 50,000, and when the number average molecular weight is less than 1,000, the drying property of the coating film is lowered, and conversely When the number average molecular weight exceeds 100,000, the surface of the coating film is easily extravasated.

The substitution position is a branch of polyoxyalkylene oil, two ends, a single end, a two-end branch, and the like. Examples of the hydrophilic group include a polyether, polyglycerin, pyrrolidone, betaine, sulfate, phosphate, and a quaternary salt. As a polyoxyalkylene surfactant, the nonionic surfactant composed of a dimethylpolysiloxane and a hydrophilic alkyl group is a nonionic surfactant, and has no aqueous solution. A general term for a surfactant which dissociates into an ion group. In addition to having a hydrophobic group, it also has a hydroxyl group as a hydrophilic group and a polyoxyalkylene chain (polygas-52-200904636 oxyethane) ) as a hydrophilic base. The hydrophilicity increases as the number of alcoholic hydroxyl groups increases, and as the polyoxyalkylene chain (polyethylene oxide chain) lengthens. When a nonionic surfactant composed of a dimethylpolysiloxane and a hydrophilic group is a polyoxyalkylene group is used, the unevenness of the low refractive index layer or the antifouling property of the film surface is enhanced. It is presumed that when the hydrophobic group formed of polymethyl siloxane is aligned to the surface, a surface of the film which is difficult to be contaminated can be formed. Effects not available with other surfactants. Specific examples of these nonionic surfactants include, for example, unicar Co., Ltd., polyoxyxane surfactants SILWET L-77, L-720, L-7001, L-7002, L-7604, Y-7006 , FZ-2101, FZ-2104, FZ-2105, FZ-2110, FZ-2118, FZ-2120, FZ-2122, FZ-2123, FZ-2130, FZ-2154, FZ-2161, FZ-2162, FZ -2163, FZ-2164, FZ-2166, FZ-2191, etc. Further, SUPERSILWET SS-2 8 0 1 'SS-2802, SS-2803, SS-2804, SS-2805, and the like can be cited. Further, 'the preferred structure of the nonionic surfactant composed of a polyoxyalkylene group as the hydrophobic group is composed of dimethyl polyoxyalkylene, and the dimethyl polyoxyalkylene moiety is A linear block copolymer which is repeatedly and repeatedly bonded to the polyoxyalkylene chain is preferred. The chain length of the main chain skeleton is relatively long, and it is superior in terms of a linear structure. It can be inferred that when the hydrophilic group and the hydrophobic group are cross-repetitive block copolymers, one active agent molecule adsorbs the surface of the cerium oxide microparticles at a large portion to cover the surface. -53-200904636 As these specific examples, for example, a polyoxyxane surfactant ABN SILWET FZ-2203, FZ-2207, FZ-2208, FZ-2222, etc., which are manufactured by Nippon Unicar Co., Ltd., etc. Among the alkane oils or polyoxyalkylene surfactants, those having a polyether base are preferred.

The fluorine-based or polyoxyalkylene-based surfactant may be used in combination with other surfactants, and examples thereof include anionic surfactants such as sulfonate-based, sulfate-based, and phosphate-based salts, and may also be used as a polymer. A nonionic surfactant such as an ether type or an ether ester type of an ethylene oxide chain hydrophilic group. The amount of the above surfactant added is 0. in the low refractive index layer coating composition. 05~2. When the content is 0% by mass, not only the water repellency, the oil repellency, and the antifouling property of the coating film but also the surface scratch resistance can be exhibited, which is preferable. Further, an acid may be added to the low refractive index layer coating composition. By adding an acid, an alkali component such as ammonia can be dissolved from the inside of the hollow fine particles, and the viscosity of the coating composition of the low refractive index layer can be prevented from increasing after the coating is applied to the coating of -54-200904636. The acid to be added may be a known inorganic acid or organic acid, but an organic acid is preferred. Examples of the organic acid include acetic acid, formic acid, propionic acid, and the like. Among them, acetic acid is preferred. The amount of the organic acid to be added is an amount corresponding to an alkali component such as ammonia from the inside of the hollow fine particles, and for the solid component in the hollow fine particle dispersion, for example, acetic acid is added in an amount of 5 to 100% by mass. Depending on the concentration of the hollow microparticle dispersion, it is generally added to the hollow microparticle dispersion. 5~30. An acid in the range of 0% by mass is preferred. Continue to explain the anti-glare anti-reflective film. The antiglare antireflection film has an arithmetic mean roughness (Ra) of the outermost surface of not more than 40 to 500 nm, preferably 60 to 300 nm. The arithmetic mean roughness (Ra) of the outermost surface of the anti-glare anti-reflection film can be measured, for example, using an optical multi-dimensional surface roughness meter RST/PLUS (manufactured by WYKO Co., Ltd.) in the same manner as the anti-glare layer. The anti-glare antireflection film is formed by a coating step of applying a coating composition on the antiglare layer to form the low refractive index layer, and drying the obtained coating film by a drying step. Further, the preferred high refractive index layer interposed between the antiglare layer and the low refractive index layer is also coated by coating. The coating method is not particularly limited, and the coating composition or coating step used in the mixing is not limited. And make a suitable choice. For example, a coating method of -55 - 200904636 can be employed, such as spin coating, roll coating, screen printing, spray coating, gravure coating, and a later-described spraying method. In the formation of the anti-glare anti-reflection film, a hardening step may be added after the drying step as necessary. Further, the anti-glare antireflection film may be subjected to a heat treatment at a temperature of 50 to 160 Torr after the production. The heat treatment time 'is appropriately determined by the set temperature, and the temperature of the heat treatment is, for example, 50 ° C, preferably 3 days or more, 30 days or less, and heat treatment temperature, for example, 1 60. When the temperature is °C, it is more than 1 minute, and the range below 1 day is better. As a curing method, a method of thermally hardening by heating, a method of curing by irradiation with light such as ultraviolet rays, or the like. When it is thermally hardened, the heating temperature is preferably 50 to 300 ° C, preferably 60 to 250 ° C, more preferably 80 to 150 ° C. When it is hardened by light irradiation, the exposure amount of the irradiation light is preferably 10 mJ/cm 2 to 10 J/cm 2 , and more preferably 100 mJ/cm 2 to 500 mJ/cm 2 . The wavelength region of the irradiated light is not particularly limited, but it is preferably a wavelength having an ultraviolet region. Specifically, a low pressure mercury lamp, a medium pressure mercury lamp, a high pressure mercury lamp, an ultra high pressure mercury lamp, a carbon arc lamp, a metal halogen lamp, a xenon lamp, or the like can be used. The irradiation conditions vary depending on the light, but the irradiation amount of the active line is usually 5 to 500 mJ/cm2, preferably 5 to 1 5 Om J/cm2, and particularly preferably 20 to 100 mJ/cm2. The anti-glare antireflection film is such that the surface of the anti-glare layer is subjected to surface treatment, and a low refractive index layer is preferably formed on the surface of the anti-glare layer on which the surface treatment is performed. In the anti-glare antireflection film, after the antiglare layer is formed, the surface of the antiglare layer is subjected to surface treatment. Preferably, a low refractive index layer is formed on the surface of the antiglare layer on which the surface treatment is performed. -56 - 200904636 The reflectance of the anti-glare anti-reflective film can be measured by a spectrophotometer. At this time, the inside of the measurement side of the sample was subjected to roughening treatment, and then light absorption treatment was performed using a black spray, and then the reflected light in the visible light region (4 Å to 700 nm) was measured. The lower the reflectance, the better, but the average 値 in the wavelength of the visible light region is preferably 2.5% or less, and the reflectance is only 2. The anti-glare antireflection film of the present invention can be expressed at less than 5%. The minimum reflectance is preferably 2 · 5 % or less, more preferably! .  Less than 5%. Further, in the wavelength region of visible light, a reflection spectrum having a flat shape is preferable. In addition, the reflected hue of the surface of the polarizing plate subjected to the anti-reflection treatment is mostly red or blue, but the reflection is high because the anti-reflection film is designed to have a high reflectance in the short-wavelength region or the long-wavelength region in the visible light region. The color of light has different requirements depending on the application. When used on the outermost surface such as FPD TV, it is required to be a natural color. In this case, it is generally preferred that the range of reflected hue is on the XYZ color system (CIE1931 color system), 0·17$χ$0·27, 0. 07Sy$0. 17. The film thickness of the low refractive index layer is determined by considering the refractive index of the layer and the color tone of the reflected light, which can be calculated by a usual method. A description will be given of a preferred high refractive index layer interposed between the antiglare layer and the low refractive index layer. It is preferred that the high refractive index layer contains metal oxide fine particles. The type of the metal oxide fine particles is not particularly limited, and for example, at least one selected from the group consisting of Ti, Zr, Sn, Sb, Cu, Fe, Mn, Pb, Cd, As, Cr, Hg, Zn, Al, Mg can be used. Metal oxides of elements of Si, P, and S. These metal oxide fine particles can be blended with trace atoms such as ruthenium 1, η, Sn, Sb, Nb, and halogen-57-200904636. Also, these mixtures are also possible. In the present invention, at least one metal oxide fine particle selected from the group consisting of an oxidation pin, cerium oxide, tin oxide, zinc oxide, indium tin oxide (ITO), cerium-doped tin oxide (cerium), and neodymium acid is used as a main component. The composition is better, especially the zinc citrate. The average particle diameter of the primary particles of these metal oxide fine particles is preferably i 〜 2,000 nm, and preferably 10 〜 150 nm. The average particle diameter of the metal oxide fine particles can be measured by an electron microscope photograph by a scanning electron microscope (SEM) or the like. The measurement can be carried out by using a particle size distribution meter such as a dynamic astigmatism method or a static astigmatism method. When the particle diameter is too small, aggregation tends to occur, and the dispersibility is deteriorated. When the particle size is too large, the smog will be significantly improved. The shape of the metal oxide microparticles is preferably a spherical shape, a spherical shape, a cubic shape, a spindle shape, a needle shape or an indefinite shape. The refractive index of the high refractive index layer is specifically higher than the refractive index of the transparent film substrate of the support, and is 1 at a wavelength of 25 ° C at 25 ° C.  5 0~1.  9 0 The range is better.

物或二氧雜戊環類、丙酮、乙酸甲酯、乙醯乙酸甲酯等。 特佳可舉出二氯甲烷或乙酸甲酯。 又,弱溶劑雖無特別限定,例如可使用甲醇、乙醇、 η-丁醇、環己烷、環己酮等。又,摻合物中含有水〇.〇1〜 2質量%者爲佳。 調製上述摻合物時,作爲纖維素酯之溶解方法,可使 用一般方法。組合加熱與加壓時,可於常壓下於沸點以上 進行加熱。以溶劑於常壓下的沸點以上且加壓下不會使溶 劑沸騰之溫度範圍內一邊加熱,一邊攪拌溶解時,可防止 凝膠或稱爲mamaco (結塊)之塊狀未溶解物的發生,故 較佳。又,將纖維素酯與弱溶劑混合成爲濕潤或膨潤後, 可再添加良溶劑進行溶解之方法亦佳。 加壓可藉由壓入氮氣等惰性氣體的方法、或藉由加熱 使溶劑之蒸氣壓上昇的方法進行。加熱由外部進行者爲佳 ,例如外套型者因容易控制溫度故較佳。 添加溶劑之加熱溫度,較高時由纖維素酯之溶解性的 觀點來看較佳,加熱溫度若過高時,因必須的壓力過大而 使生產性變差。較佳加熱溫度爲 45〜120 °C,以 60〜 110 °C爲佳,70 °C〜105 °C爲較佳。又,壓力可調整至設定 -88- 200904636 溫度下溶劑不會沸騰之程度。 又,亦可使用冷卻溶解法,藉此乙酸甲酯等溶劑中可 溶解纖維素酯。 繼續,將該纖維素酯溶液使用濾紙等適當過濾材進行 過濾。作爲過濾材’欲除去不溶物等以絕對過濾精度較小 者爲佳’但絕對過濾精度過小時,容易產生過濾材阻塞的 問題。因此以絕對過濾精度爲0.008mm以下的濾材爲佳 ,0.001〜0.008mm之濾材者爲較佳,0.003〜〇.〇〇6mm之 濾材者爲更佳。 濾材之材質並無特別限定,可使用一般的濾材,聚丙 烯、鐵佛龍(註冊商標)等塑質製之濾材、或不鏽鋼等金 屬製濾材因無繊維脫落等而較佳。藉由過濾,含於原料之 纖維素酯的雜質,特別爲除去、減低亮點異物而較佳。 摻合物的過濾可藉由一般方法進行,於溶劑之常壓下 的沸點以上,且加壓下溶劑不會沸騰之溫度範圍內一邊加 熱一邊過濾之方法’可減低過濾前後之濾壓差(稱爲差壓 )的上昇而較佳。較佳溫度爲45〜120。(:,以45〜70 °C爲 較佳,4 5〜5 5 °C更佳。 濾壓較小爲佳。濾壓以1.6MPa以下時爲佳,l.2MPa 以下時爲較佳,l.OMPa以下時爲更佳。 繼續對於摻合物的流延做說明。 流延(澆鑄)步驟中的金屬支持體以可對表面進行鏡 面加工者爲佳,作爲金屬支持體,使用以不鏽鋼輸送帶或 鑄物進行表面鍍敷加工的轉筒爲佳。澆鑄寬度可爲i〜4m -89- 200904636 。流延步驟之金屬支持體的表面溫度設定爲-5 0 °C〜溶劑 沸騰不發泡之溫度以下。溫度較高時可使織物之乾燥速度 加快故較佳,若過高時,織物會發泡、或會使平面性劣化 。作爲較佳金屬支持體溫度以 0〜1 0(TC爲適宜,以5〜 3 〇 °C爲更佳。又,藉由冷卻可使織物(web )凝膠化,以 含有大量殘留溶劑之狀態下自金屬支持體剝離亦爲較佳方 法。控制金屬支持體之溫度的方法,雖無特別限定,但可 使用吹入溫風或冷風之方法、或將溫水與金屬支持體裏側 接觸之方法。使用溫水時,可有效率地進行熱之傳達,故 金屬支持體的溫度到達一定之時間較短而較佳。使用溫風 時,考慮到溶劑之蒸發潛熱會使織物之溫度降低,使用溶 劑沸點以上之溫風可防止發泡下,亦可使用比目的溫度還 高之風。特別爲自流延至剝離之間,改變金屬支持體之溫 度、及乾燥風之溫度,而有效率地進行乾燥爲佳。 欲使纖維素酯薄膜顯示良好平面性,自金屬支持體剝 離織物時的殘留溶劑量以1 0〜1 5 0質量%爲佳,更佳爲 20〜40質量%或60〜130質量%,特佳爲20〜30質量% 或70〜120質量%。 本發明中,殘留溶劑量定義如下述式。 殘留溶劑量(質量% ) ={(Μ-Ν)/Ν}χ100 且,Μ爲織物或薄膜於製造中或製造後的任意時點所 採取之試料質量,Ν爲Μ於1 1 5 t下進行1小時加熱後之 質量。 -90- 200904636 又,纖維素酯薄膜之乾燥步驟中,將織物自金屬支持 體剝離後進行乾燥,使殘留溶劑量爲1質量%以下者爲隹 ’更佳爲〇·1質量%以下,特佳爲0〜〇_〇1質量%以下。 薄膜乾燥步驟中,一般採用以輥乾燥方式(將配置於 上下的多數輥使織物(web)交互通過並乾燥之方式)或 拉幅器方式搬送織物下進行乾燥之方式。 欲製造本發明之使用於防眩性薄膜的纖維素酯薄膜時 ,自金屬支持體剝離後之織物殘留溶劑量較多處馬上於搬 送方向進行延伸,且以將織物之兩端以壓板等夾住之拉幅

下進行剝離爲佳,特佳爲220〜300N/m。 乾燥織物(web )之手段並無特別限定,一般可藉由 熱風、紅外線、加熱輥、微波等進行,但由簡便之觀點來 看,進行熱風者爲佳。 織物的乾燥步驟中之乾燥溫度爲30〜150°C以段階性 提高方式進行爲佳,50〜14CTC之範圍下進行時’可使尺 寸安定性良好而更佳。 纖維素酯薄膜之膜厚雖無特別限定,但以〜2G() -91 - 200904636 A m爲佳。因具有優良的平面性與生產性,故纖維素酯薄 膜之膜厚以10〜70/zm爲特佳。 更佳爲20〜60#m。最佳爲30〜60//m。又,藉由共 流延法作爲多層構成可使用纖維素酯薄膜爲佳。纖維素酯 爲多層構成時’亦具有含有紫外線吸收劑與可塑劑之層, 此可爲核心層、表面層、或其雙方皆可。 又,作爲透明薄膜基材之表面上形成算術平均粗度( Ra)爲未達50〜lOOOnm之凹凸形狀的方法,例如於透明 薄膜基材上藉由壓型而形成者爲佳。 繼續對於熔融流延製膜法做說明。熔融流延製膜法中 ,未使用溶劑(例如二氯甲烷等),藉由加熱熔融之熔融 流延的成形法,更詳細爲可分類爲熔融壓出成形法、加壓 成形法、吹塑法、射出成形法、吹氣成形法、延伸成形法 等。其中欲得到具有優良的機械性強度、及表面精度等之 纖維素酯薄膜,以熔融押出法爲優良。 繼續舉出熔融壓出法之例子,對於藉由熔融流延製膜

件可於與其他聚酯等熱可塑性樹脂所使用的相同條件下進 行。材料以預先乾燥爲佳。以真空或減壓乾燥機或除濕熱 風乾燥機等將水分乾燥至lOOOppm以下,較佳爲200ppm 以下爲佳。 以熱風或真空或減壓下進行乾燥之纖維素酯系樹脂, 使用壓出機1,例如以壓出溫度2 0 0〜3 0 0。(:程度下進行熔 融’以葉片型過濾器2等進行過濾將異物除去。 由供給料斗(圖示略)導入壓出機1時,真空下或減 壓下或惰性氣體環境氣體下,防止氧或水分的影響進而防 止氧化分解等爲佳。 未預先混合可塑劑等添加劑時,可於壓出機途中進行 混煉。欲可均勻地添加’使用靜態攪拌器3等混合裝置爲 隹。 本發明中’纖維素樹脂與其他視必要所添加的安定化 劑等添加劑,可於熔融前進行混合爲佳。纖維素樹脂與安 定化劑於最初混合更佳。混合可使用混合機等進行,又如 -93- 200904636 上述,亦可於纖維素樹脂調製過程中混合。使用混合機時 ,可使用 v型混合機、圓錐螺旋型混合機、水平圓筒型 混合機等、亨舍爾攪拌機、螺帶式混合機等一般混合機。 如上述將薄膜構成材料混合後,將該混合物可使用壓 出機1經直接熔融而製膜,但一旦將薄膜構成材料進行顆 粒化後,可將該顆粒以壓出機1經熔融後製膜。又,薄膜 構成材料爲含有熔點相異的複數材料時,僅於可熔融熔點 較低的材料的溫度下,一旦製作成所謂的米通半熔融物, 再將半熔融物投入於壓出機1中而製膜。 於薄膜構成材料若含有容易熱分解之材料時,以減少 熔融次數爲目的下,未製造顆粒下進行直接製膜的方法、 或如上述作成如米通之半熔融物後再製膜之方法爲佳。 壓出機1可使用可購得之種種壓出機,但以熔融混煉 壓出機爲佳,單軸壓出機或2軸壓出機皆可。由薄膜構成 材料未製造顆粒下進行直接製膜時,因適當的混煉度爲必 要’故使用2軸壓出機爲佳,亦可爲單軸壓出機、或將螺 旋形狀變更爲Maddock型、Unimelt型、Dulmage等混煉 型之螺旋可得到適度混煉,故可使用。 作爲薄膜構成材料,一旦使用顆粒或米通半熔融物時 ’可使用單軸壓出機,亦可使用2軸壓出機。 壓出機1內、及壓出後之冷卻步驟可由氮氣等惰性氣 體取代、或藉由減壓可降低氧濃度爲佳。 壓出機1內的薄膜構成材料之熔融溫度,依據薄膜構 成材料之黏度或吐出量、製造之薄片厚度等其較佳條件相 -94- 200904636 異’但一般而言對於薄膜之玻璃轉移溫度(Tg ) , 以上’ Tg+l〇〇°c以下,較佳爲Tg+lOt:以上,Tg + 以下。壓出時之熔融黏度爲10〜1 000 00泊,較佳爲 〜10000泊〇 又,壓出機1內之薄膜構成材料的滯留時間較短 ,5分鐘以內爲佳,較佳爲3分鐘以內,更佳爲2分 內。滞留時間易受控於壓出機1之種類、壓出條件, 由調整材料之供給量或L/D、螺旋轉動數、螺旋溝之 等可縮短滯留時間。 壓出機1的螺旋形狀或轉動數等可藉由薄膜構成 之黏度或吐出量等做適宜選擇。本發明中之壓出機1 斷速度爲1 /秒〜1 0 0 0 0 /秒,較佳爲 5 /秒〜1 0 0 0 /秒, 爲1 0 /秒〜1 0 0 /秒。 作爲本發明所使用的壓出機1,一般可使用塑質 機。 自壓出機1所壓出的薄膜構成材料,被送至流延 4,由流延塑模4之隙縫壓出成薄膜狀。流延塑模4 使用於製造薄片或薄膜者即可並無特別限定。 作爲流延塑模4之材質,可舉出將硬鉻、碳化鉻 化鉻、碳化鈦、碳氮化鈦、氮化鈦、超鋼、陶瓷(碳 、氧化鋁、氧化鉻)等進行溶射或鍍敷,作爲表面加 可舉出施予使用拋光#1000支以下的磨石進行硏磨’ #1 000支以上的鑽石磨石之平面切割(切割方向與樹

而將嵌段36進行一般空調冷卻下,增減埋入電加熱 器37之入力並調整嵌段36之溫度,藉此熱伸縮加熱螺栓 3 5,使可撓性突出3 3變位而調整薄膜厚度。於塑模後流 之所要處設置厚度計,藉此經檢測的織物厚度情報放入控 制裝置中,將該厚度情報以控制裝置與設定厚度情報作比 較,可藉由來自同裝置之修正控制量的信號來控制加熱螺 栓之發熱體的電力或操作率。 加熱螺栓較佳爲長度20〜40 cm、直徑7〜14mm,例 如數十根之複數加熱螺栓排列成較佳間距2 0〜4 0 mm。取 代加熱螺栓,亦可設置於軸方向以手動使其前後移動來調 節隙縫間隔之螺栓作爲主體的間隔調節構件。藉由間隔調 節構件經調節之隙縫間隔一般爲200〜1 000 μ m,較佳爲 -96- 200904636 300 〜800/z m,更佳爲 400〜600y m。 第1冷卻輥5〜第3冷卻輥8爲壁厚20〜 之無縫鋼管製’且表面經鏡面加工者。其內部 冷卻液之配管’構成爲配管藉由流入之冷卻液 輥上的薄膜之熱。 一方面,銜接於第1冷卻輥5之接觸輥6 有彈性,藉由對於第1冷卻輥5之壓力,沿著 5之表面而變形’與第1輥5之間形成壓區。 圖4表示接觸輥6的一實施形態(以下稱 )之槪略截面圖。如圖所示’接觸輥A爲於 套管4 1的內部配置彈性滾筒4 2者。 金屬套管41爲厚度0.3mm之不鏽鋼製者 撓性。金屬套管41若過薄時強度會不足,相

1 b外側之中間通路6 2 a、6 2 b之流出口 5 2 a、及流 人□ 52b 。 又,外筒51爲,因具有與橡膠彈性相近的柔軟性與 可撓性、復原性,於彈性力學的薄壁圓筒理論可適用之範 圍內達到薄壁化。該薄壁圓筒理論所評估的可撓性以壁厚 t/輥半徑r之比表示,t/r的比越小,可撓性越高。該接觸 輥B中,t/r S 0 · 0 3時,可撓性爲最適條件。 一般所使用的接觸輥爲’輥徑:R = 200〜5 00mm (輥 -98- 200904636 半徑:r = R/2)、輥有效寬度:L = 500〜1600mm,輥半徑 r/輥有效寬度L之比:r/L < 1下,其橫長形狀。 如圖6所示’例如輥徑:R = 3〇〇mm、輥有效寬度: L=1 200mm時’壁厚:t之最適範圍爲15〇x〇.〇3=4.5mm以 下’但對於熔融薄片寬度爲13〇〇mm而言,平均線壓以 9 8N/cm夾壓時’與同一形狀的橡膠輥比較,使外筒51的 壁厚爲3mm時反彈定數亦相等,外筒51與冷卻輥之壓區 的輕轉動方向之壓區寬度k亦爲約9mni,該橡膠輕之壓 區寬度顯示接近約1 2mm之値,得知相同條件下可夾壓。 且’該壓區寬度k中的擦曲量爲〇.〇5〜O.lmin程度。 其中,作爲〇1^0.03,一般輥徑:11 = 200〜500111111時 ,特別以2mm S t S 5 mm之範圍時,可得到充分的可撓性 ’且藉由機械加工的薄壁化亦容易實施,成爲極實用之範 圍。壁厚爲2mm以下時,加工時的彈性變形無法進行高 精度加工。 該的換算値對於一般輥徑而言,雖成 爲0.008$t/rS0.05,但實用上於t/r = 0.03之條件下,與 輥徑成比例且壁厚亦變大爲佳。例如輥徑:R = 200中, t = 2〜3mm’輕徑:R = 500中,t = 4〜5mm之範圍下選擇。 該接觸輕A、B爲,藉由未圖示之供能(energizing )手段,於第1冷卻輥提供能量。該供能手段之供能力作 爲F,除以於壓區(nip)之薄膜的沿著第1冷卻輥5之 轉動軸方向的幅度W之値=F/W (線壓)設定爲9.8〜 1 4 7N/cm ° -99- 200904636 本發明中,接觸輥A、B與第1冷卻輥5之間形成壓 區,該壓區(nip )於薄膜通過之間使其矯正成平面性即 可。因此,與接觸輥由剛體所構成,與第1冷卻輥之間未 形成壓區(nip )時相比較,較小線壓下經過長時間夾壓 薄膜,故可更能確實地矯正平面性。即,線壓若比 9.8N/cm小時,塑膜線無法充分地消除。 相反地,線壓若比147N/cm大時,薄膜不容易通過 壓區(nip),薄膜厚度反而容易引起不均。 又,接觸輥A、B之表面由金屬所構成時,與接觸輥 表面爲橡膠的情況相比較,更能平滑接觸輥A、B之表面 ,故可得到平滑性較高的薄膜。且,作爲彈性滾筒42之 彈性體44的材質,可使用乙烯-伸丙基橡膠、氯丁橡膠、 矽橡膠等。 而欲藉由接觸輥6更能消除塑膜線,接觸輥6夾壓薄 膜時的薄膜黏度必須爲適當範圍爲重要。又,已知纖維素 酯爲溫度所造成的黏度變化較爲大。 因此,欲將接觸輥6夾壓纖維素酯薄膜時的黏度設定 於適當範圍,接觸輥6夾壓纖維素酯薄膜時的薄膜溫度必 須設定於適當範圍爲重要。 將纖維素酯薄膜的玻璃轉移溫度作爲(Tg)時,薄膜 夾壓於接觸輥6前的薄膜溫度T以滿足Tg < T < Tg + 1 l〇°C之條件者爲佳。薄膜溫度T若比Tg低時,薄膜黏度 會過高,而無法矯正塑膜線。 相反地’薄膜之溫度T若比Tg + 110 高時,薄膜表 -100- 200904636 面與輥無法均勻地黏著’仍然無法矯正塑膜線。較佳爲 Tg + lot: < T< Tg + 9(TC,更佳爲 Tg

著場所,施予加熱器進行加熱等處置爲佳。吸引壓若過小 時,昇華物無法有效地被吸引,故必須要有適當的吸引壓 〇 將自T塑模4之熔融狀態的薄膜狀纖維素酯系樹脂, 以第1輥(第1冷卻輥)5、第2冷卻輥7、及第3冷卻 輥8之順序下密著地搬送且使其冷卻固化,得到未延伸之 -101 - 200904636 纖維素酯系樹脂薄膜1 0。 如圖1所示的本發明之實施形態中,自第3冷卻輥8 藉由剝離輥9剝離之經冷卻固化的未延伸薄膜1 〇爲,經 由跳動輥(薄膜張力調整輥)Η導入延伸機12,於此將 薄膜1〇進行橫方向(寬方向)。藉由該延伸,配向薄膜 中的分子。 將薄膜往寬方向延伸之方法,可使用公知拉幅器等方 法。 一方面,偏光薄膜的透過軸一般亦爲寬方向。偏光薄 膜之透過軸與光學薄膜之遲相軸爲平行下將層合之偏光板 裝入液晶顯示裝置中,可提高液晶顯示裝置之顯示對比, 同時亦可得到良好視野角。 薄膜構成材料之玻璃轉移溫度(Tg )可藉由構成薄膜 之材料種類、及所構成之材料比率的不同來控制。作爲纖 維素酯薄膜製造相位差薄膜時,Tg爲1 2 0 °c以上,較佳爲 1 3 5 °C以上。液晶顯示裝置中,影像之顯像狀態中,裝置 本身的溫度上昇,例如來自光源之溫度上昇可使薄膜之溫 度環境產生變化。 此時比薄膜的使用環境溫度,薄膜之Tg爲更低時, 會使得藉由延伸固定於薄膜內部之分子配向狀態所造成的 滯溜値、及作爲薄膜之尺寸形狀產生大變化。薄膜之Tg 過高時,使薄膜構成材料進行薄膜化時的溫度會過高而提 高加熱之能量消費,又進行薄膜化時的材料本身會分解, 且藉此會產生著色,因此Tg以25 0 °c以下爲佳。 -102- 200904636 又,延伸步驟中可進行公知熱固定條件、冷卻、緩和 處理,適宜地選出具有依目的之光學薄膜所要求之特性者 即可。 欲賦予相位差薄膜之物性與液晶顯示裝置的視野角擴 大時的相位差薄膜之功能’可適宜地選擇上述延伸步驟、 熱固定處理而進行。含有如此延伸步驟、熱固定處理時, 加熱加壓步驟爲這些延伸步驟、熱固定處理之前進行。 製造作爲纖維素酯薄膜之相位差薄膜時,且複合纖維 素酯薄膜之功能時,必須進行折射率控制,但該折射率控 制可藉由延伸操作來進行’又以延伸操作爲較佳方法。以 下對於該延伸方法作說明。 相位差薄膜之延伸步驟中’於纖維素樹脂之1方向延 伸1.0〜2.0倍、及於薄膜面內與此直交之方向上延伸 1 . 0 1〜2.5倍時,可控制必要的滞留値Ro及Rt、或可改 善平面性。 其中,所謂Ro爲顯示面內滯留値,其爲面內之長方 向MD的折射率與寬方向TD之折射率的差乘上厚度者, Rt爲顯示厚度方向滯留値,其爲面內的折射率(長方向 MD與寬方向TD之平均)與厚度方向之折射率的差乘上 厚度者。 延伸爲,例如可於薄膜之長方向及與此於薄膜面內呈 直交之方向、即對於寬方向,逐次或同時進行。此時對於 至少1方向的延伸倍率過小時,無法得到充分的相位差, 過大時難以延伸而容易產生薄膜破斷。 -103- 200904636 於相互直交之2軸方向進行延伸爲,使薄膜之折射率 nx、ny、nz於所定範圍之有效方法。其中,nx表示長手 MD方向之折射率,ny表示寬TD方向之折射率,nz表示 厚度方向之折射率。 例如,於熔融流延方向進行延伸時,寬方向之收縮若 過大,nz之値會過大。此時,抑制薄膜之寬度收縮、或 於寬方向亦進行延伸來改善。於寬方向進行延伸時,於寬 方向會產生折射率不均分佈。 此分佈有時於使用拉幅器法時出現,其被推測爲將薄 膜於寬方向進行延伸時,於薄膜中央部會產生收縮力,因 端部被固定所產生的現象,即產生所謂的bowing現象。 此時亦於流延方向進行延伸時,可抑制bowing現象,可 減少寬方向之相位差分佈不均。 藉由於互相平行的2軸方向進行延伸,可減少所得之 薄膜的膜厚變動。相位差薄膜之膜厚變動過大時,會使相 位差不均,使用於液晶顯示器時,會成爲著色等不均之問 題。 纖維素酯薄膜的膜厚變動爲±3%,更佳爲±1%之範圍 。於如上述目的中,於互相直交之2軸方向進行延伸的方 法爲有效,互相直交之2軸方向的延伸倍率於最終各於流 延方向爲1.0〜2.0倍,於寬方向爲1.01〜2.5倍之範圍爲 佳,更佳爲得到必須於流延方向爲1 · 0 1〜1 · 5倍,於寬方 向爲1.05〜2.0倍之範圍內進行的滯留値。 於長方向存在偏光子之吸收軸時,可使於寬方向上偏 -104- 200904636 光子之透過軸爲一致。欲得到長尺狀偏光板,相位差薄膜 於寬方向進行延伸至得到遲相軸爲佳。 對於應力,使用得到正複折射的纖維素酯時’由上述 構成於寬方向進行延伸時,相位差薄膜的遲相軸可於寬方 向賦予應力。此時,欲提高顯示品質,相位差薄膜之遲相 軸以寬方向爲佳,欲得到目的之滯留値必須滿足, 式:(寬方向的延伸倍率)>(流延方向的延伸倍率) 之條件。 延伸後,將薄膜之端部藉由縱剪切機13剪裁作爲製 品之寬度的隙縫後,藉由滾邊環14及背輥15所成之凸邊 加工裝置,於薄膜兩端部施行凸邊加工(knurled,壓紋 加工),藉由捲取機1 6進行捲取,防止纖維素酯薄膜( 元捲)F中之貼合或擦傷之產生。 凸邊加工之方法’可將側面具有凸凹圖形的金屬環藉 由加熱或加壓而進行加工。且,薄膜兩端部之壓板把持部 分一般爲已變形,無法作爲薄膜製品使用,故經切除後可 作爲原料再利用。 繼續,薄膜之捲取步驟爲,將圓筒形捲薄膜的外周面 、與此前的移動式搬送輥的外周面之間的最短距離保持一 定下將薄膜於捲取筒進行捲取者。且,捲取筒之前,可設 有除去或減低薄膜之表面電位的除靜電風機等手段。 有關本發明的纖維素酯薄膜之製造的捲取機可使用一 般使用者’可由定張力法、定轉矩法、傾斜張力法、內部 應力一定之程式張力控制法等捲取方法進行捲取。且,纖 -105- 200904636 維素酯薄膜之捲取時的初期捲取張力以90.2〜3 00.8N/m 爲佳。 薄膜之捲取步驟中,於溫度20〜30 °C、濕度20〜60 % RH之環境條件下,捲取薄膜爲佳。如此規定於薄膜捲 取步驟之溫度及濕度,可提高厚度方向滯留値(Rt)之濕 度變化耐性。 捲取步驟中的溫度未達2 0°C時,會產生皴紋,薄膜捲 品質的劣化使得無法實用而不佳。薄膜之捲取步驟中的溫 度若超過30°C時’仍然會產生皺紋,因薄膜捲品質的劣化 而無法實用而不佳。 又’薄膜之捲取步驟中之濕度若未達20% RH時,容 易產生靜電,薄膜捲品質之劣化使得無法實用而不佳。薄 膜之捲取步驟中的濕度若超過60%RH時,捲品質、貼合 故障、搬送性等會劣化而不佳。 將纖維素酯薄膜捲取成輥狀時,作爲捲核心,僅爲圓 筒上之的核心即可,可爲任種材質,但較佳爲中空塑質核 心’作爲塑質材料以可耐住加熱處理溫度之耐熱性塑質即 可’可舉出酚樹脂、二甲苯樹脂、三聚氰胺樹脂、聚酯樹 脂、環氧基樹脂等樹脂。 又’藉由玻璃繊維等塡充材之經強化熱硬化性樹脂爲 佳。例如,中空塑質核心:使用FRP製之外徑6英吋( 以下’英吋表示2.54cm。)、內徑5英吋之捲核心。 對於這些捲核心之捲數,以1〇〇捲以上爲佳,5〇〇捲 以上爲更佳’捲厚以5cm以上爲佳,長度爲5 00〜1 0000m -106- 200904636 ,薄膜寬度以1〜5m爲佳’特佳爲1.5〜4m。 製造廣幅薄膜時’亦可於捲取前對薄膜施予隙縫加工 後得到2〜3根輥薄膜。 製膜步驟中,經剪裁的薄膜兩端之壓板把持部分’經 粉碎處理後、或視必要進行造粒處理後’可作爲相同品種 之薄膜用原料或相異品種之薄膜用原料再利用。 防眩層之表面處理中可使用洗淨法、鹼處理法、面電 漿處理法、高頻率放電電漿法 '電子束法、離子束法、濺 射法、酸處理、電暈處理法、大氣壓電漿法等。 其中,所謂電暈處理爲,大氣壓下,電極間外加1 kV 以上高電壓,使其放電下進行之處理,可使用春日電機股 份有限公司或股份有限公司Toyo電機等販賣的裝置進行 。電暈放電處理之強度爲,取決於電極間距離、每單位面 積之輸出、發生器之頻率數。電暈處理裝置的一方電極( A電極)可使用販賣品,但材質可選自鋁、不鏽鋼等。另 一方爲要包住塑質薄膜的電極(B電極),且欲使電暈處 理可安定且均勻下實施的對於A電極之一定距離上所設 置之輕電極。此亦可使用一般購得者,材質爲銘、不鏽鋼 、及彼等金屬所製作之輥上可使陶瓷、聚矽氧烷、EP T橡 膠、海普龍橡膠等作爲裏襯(lining)之輥爲佳。 使用於電暈處理之頻率數爲20〜100 kHz之頻率數, 以30〜60kHz之頻率數爲佳。頻率數降低時,電暈處理之 均一性會劣化’而產生電暈處理不均。又,頻率數過大時 ,進行高輸出之電暈處理時,雖無特別問題,但實施低輸 -107- 200904636 出之電暈處理時,難以進行安定之處理,結果會產生處理 不均。 電暈處理的輸出爲 1〜5w_min./m2,以 2〜 4wmin./m2之輸出爲佳。電極與薄膜之距離爲5〜50mm ,但較佳爲10〜35mm。間隙過開時,欲維持一定輸出而 必須要高電壓,容易產生不均。又,間隙過於狹隘時,外 加電壓會過低,而容易產生不均。且,搬運薄膜進行連續 處理時,電極上會接觸到薄膜而產生擦傷^ 又,作爲鹼處理法,僅將塗佈設置防眩層之薄膜浸漬 於鹼水溶液的方法即可,並無特別限定。 作爲鹼水溶液,可使用氫氧化鈉水溶液、氫氧化鉀水 溶液 '氣水溶液等,其中亦以氫氧化鈉水溶液爲佳。 鹼水溶液之鹼濃度,例如氫氧化鈉濃度以0.1〜2 5質 量%爲佳,0·5〜15質量%較佳。 鹼處理溫度一般爲10〜80 °C,較佳爲20〜60 t:。 鹼處理時間爲5秒〜5分鐘,較佳爲3 0秒〜3分鐘。

Examples of the inorganic compound include fine particles and titanium dioxide. Alumina, chromium oxide, calcium carbonate, calcium carbonate, talc, sticky -85- 200904636 soil, calcined clay, calcined calcium citrate, water and calcium citrate Aluminum citrate, magnesium citrate, and calcium phosphate. Preferably, the sulphur dioxide is preferred from the viewpoint of low turbidity of the fine particles. The average diameter of the primary particles of the fine particles is preferably 5 to 50 nm, more preferably 7 to 20 nm. . These are mainly those which contain two agglomerates having a particle diameter of 0.05 to 0.3/m. The content of these fine particles in the cellulose ester film is preferably 〇5 ~1% by mass, particularly preferably 0.1 to 0.5% by mass. In the case of the cellulose ester film composed of a plurality of layers of the co-flowing method, it is preferred to contain the added amount of fine particles on the surface.

A seller who is a trade name of Aer〇SilR976 and R811 (manufactured by Japan Aerosil Co., Ltd.) can be used. Further, polymer microparticles can also be used, and examples of the polymer microparticles include a polysiloxane resin, a fluororesin, and an acrylic resin. Among them, a polyoxyalkylene resin is preferred, and a network structure having a three-dimensional structure is particularly preferred. For example, Tospearl 103, the same 105, the same 108, the same 120, the same 145, the same 3120, and the same 240 (the above Toshiba can be used) The trade name of the manufacturer of the siloxane is a vendor. Among them, Aerosil 200V and Aerosil R972V are particularly good because they can maintain the lower turbidity of the cellulose ester film and reduce the friction coefficient, which is particularly good -86-200904636. In the cellulose ester film used in the present invention, the active energy ray-curable resin layer preferably has an inner side dynamic friction coefficient of 1.0 or less. In the present invention, the cellulose vinegar film can be produced by a solution casting film forming method or a melt casting film forming method. The following is a detailed description of the method for producing the cellulose ester film in the solution casting film forming method. The cellulose ester film is produced by dissolving a cellulose ester and an additive in a solvent to prepare a step of the blend, and casting the blend on a metal belt of a conveyor belt or a drum. a step of drying the cast blend as a web, a step of peeling off from the metal support, a step of stretching or widening, a step of further drying, and winding the processed film The steps are carried out. The procedure for preparing the blend is explained. The concentration of the cellulose ester in the blend is preferably such that the drying load after casting on the metal support can be reduced when the concentration is high, but if the concentration of the cellulose ester is too high, the load during filtration increases, so that the filtration is performed. The purity is deteriorated. The concentration which can be made two is preferably 10 to 35 mass%, more preferably 15 to 25 mass%. The solvent to be used for the blending may be used singly or in combination of two or more. However, when a good solvent of a cellulose ester is mixed with a weak solvent, it is preferably from the viewpoint of production efficiency, and when the good solvent is large, the cellulose ester is used. The solubility is preferred. The mixing ratio of the good solvent to the weak solvent is preferably from 70 to 98% by mass of the good solvent and from 2 to 30% by mass of the weak solvent. The term "good solvent" or "weak solvent" is defined as a good solvent in which the cellulose ester used alone is dissolved, and a weak solvent in the case where it is swellable or insoluble. Therefore, by -87 - 200904636, the degree of substitution of the thiol group of the cellulose ester can be changed to a good solvent or a weak solvent. For example, when acetone is used as a solvent, the cellulose ester of the cellulose ester (the degree of substitution of acetyl group 2.4), Cellulose acetate propionate becomes a good solvent, and cellulose acetate (acetylation degree of ethylene 2.8) becomes a weak solvent. The good solvent is not particularly limited, and examples thereof include organic halogen compounds such as dichloromethane, dioxolane, acetone, methyl acetate, and ethyl acetate. Particularly preferred are dichloromethane or methyl acetate. Further, the weak solvent is not particularly limited, and for example, methanol, ethanol, η-butanol, cyclohexane, cyclohexanone or the like can be used. Further, it is preferred that the blend contains hydrazine. 〇 1 to 2% by mass. When the above blend is prepared, a general method can be employed as a method of dissolving the cellulose ester. When combined heating and pressurization, it can be heated at a boiling point or higher at normal pressure. When the solvent is heated at a temperature higher than the boiling point of normal pressure and does not boil the solvent under pressure, it can prevent the occurrence of gel or block undissolved matter called mamaco (agglomeration) while stirring and dissolving. Therefore, it is better. Further, it is also preferred to mix the cellulose ester with a weak solvent to form a wet or swell, and then add a good solvent to dissolve. The pressurization can be carried out by a method of pressurizing an inert gas such as nitrogen or a method of increasing the vapor pressure of the solvent by heating. It is preferable that the heating is performed by the outside, and for example, the jacket type is preferable because it is easy to control the temperature. The heating temperature at which the solvent is added is preferably from the viewpoint of solubility of the cellulose ester at a high temperature, and if the heating temperature is too high, the productivity is deteriorated due to an excessively large pressure. The heating temperature is preferably 45 to 120 ° C, preferably 60 to 110 ° C, and preferably 70 ° C to 105 ° C. Also, the pressure can be adjusted to the extent that the solvent does not boil at temperatures from -88 to 200904636. Further, a cooling dissolution method can also be used, whereby the cellulose ester can be dissolved in a solvent such as methyl acetate. Further, the cellulose ester solution is filtered using a suitable filter material such as filter paper. As the filter material, it is preferable to remove the insoluble matter or the like with a small absolute filtration accuracy. However, if the absolute filtration accuracy is too small, the filter material is likely to be clogged. Therefore, it is preferable that the filter material having an absolute filtration accuracy of 0.008 mm or less is preferable, and a filter material of 0.001 to 0.008 mm is preferable, and a filter material of 0.003 to 〇. 〇〇 6 mm is more preferable. The material of the filter material is not particularly limited, and a general filter medium can be used, and a plastic filter material such as polypropylene or Teflon (registered trademark) or a metal filter material such as stainless steel is preferable because it does not fall off. The impurities contained in the cellulose ester of the raw material are preferably filtered to remove or reduce bright foreign matter. The filtration of the blend can be carried out by a general method, and the method of filtering while heating at a temperature above the boiling point of the solvent at a normal pressure of the solvent and under boiling under the pressure of the solvent can reduce the filtration pressure difference before and after the filtration ( It is better to refer to the rise of the differential pressure. The preferred temperature is 45 to 120. (:, preferably 45 to 70 ° C, preferably 4 5 to 5 5 ° C. The filtration pressure is preferably small. The filtration pressure is preferably 1.6 MPa or less, and preferably less than 1.2 MPa. It is better to be below OMPa. Continue to describe the casting of the blend. The metal support in the casting (casting) step is preferably mirror-finished on the surface, and used as a metal support in stainless steel. The drum with surface or plating for surface plating is preferred. The casting width can be i~4m -89- 200904636. The surface temperature of the metal support in the casting step is set to -5 0 °C~ solvent boiling does not foam Below the temperature, when the temperature is high, the drying speed of the fabric can be increased, so that if the temperature is too high, the fabric will foam or the planarity will be deteriorated. As a preferred metal support, the temperature is 0 to 1 0 (TC). Preferably, it is preferably 5 to 3 〇 ° C. Further, it is preferable to gel the web by cooling and peel off from the metal support in a state containing a large amount of residual solvent. The method of supporting the temperature of the body is not particularly limited, but may be blown into a warm or cold air. Method, or a method of contacting warm water with the inner side of the metal support. When warm water is used, heat can be efficiently transmitted, so that the temperature of the metal support reaches a certain period of time is shorter and better. When using warm air, Considering the latent heat of evaporation of the solvent, the temperature of the fabric is lowered, and the warm air above the boiling point of the solvent can be used to prevent foaming, and a wind higher than the target temperature can be used. Especially for self-casting to peeling, the metal support is changed. The temperature and the temperature of the dry air are preferably dried efficiently. To make the cellulose ester film exhibit good planarity, the residual solvent amount when peeling the fabric from the metal support is preferably 10 to 150% by mass. More preferably, it is 20 to 40% by mass or 60 to 130% by mass, particularly preferably 20 to 30% by mass or 70 to 120% by mass. In the present invention, the amount of residual solvent is defined as the following formula: Residual solvent amount (% by mass) ={(Μ-Ν)/Ν}χ100 Moreover, the quality of the sample taken at any point during or after manufacture of the fabric or film is the mass after heating for 1 hour at 1 1 5 t. -90- 200904636 Again, fiber In the drying step of the ester film, the woven fabric is peeled off from the metal support and then dried, and the amount of the residual solvent is 1% by mass or less, more preferably 〇·1% by mass or less, and particularly preferably 0 to 〇_〇1. In the film drying step, a method of drying by a roll drying method (a method in which a plurality of rolls disposed on the upper and lower sides are used to allow the web to pass through and drying) or a tenter method to carry the fabric is generally used. When the cellulose ester film used for the anti-glare film of the present invention is used, the amount of residual solvent of the fabric after peeling from the metal support is immediately extended in the conveying direction, and the both ends of the fabric are sandwiched by a press plate or the like. It is particularly preferable that the tenter method is extended in the width direction. The preferred stretching ratio in both the longitudinal direction and the transverse direction is 1.05 to 1_5 times, preferably 1.05 to 1.3 times, and more preferably 1.05 to 1.15 times. It is preferable to extend the longitudinal direction and the lateral direction so that the area is 1.1 to 2 times. This can be obtained by the stretching ratio in the longitudinal direction of the stretching magnification X in the horizontal direction. It is preferable to extend in the longitudinal direction immediately after peeling, and it is preferable to extend by the peeling tension and the conveyance tension thereafter. For example, peeling is preferably carried out at a peeling tension of 2 1 ON/m or more, and particularly preferably 220 to 300 N/m. The means for drying the web is not particularly limited, and it can be generally carried out by hot air, infrared rays, heating rolls, microwaves, etc., but it is preferable from the viewpoint of convenience. The drying temperature in the drying step of the woven fabric is preferably from 30 to 150 ° C in a stepwise manner, and when it is carried out in the range of from 50 to 14 CTC, the dimensional stability is better and more preferable. The film thickness of the cellulose ester film is not particularly limited, but is preferably 〜2G() -91 - 200904636 A m. The film thickness of the cellulose ester film is particularly preferably 10 to 70/zm because of its excellent planarity and productivity. More preferably 20~60#m. The best is 30~60//m. Further, a cellulose ester film can be preferably used as the multilayer structure by the co-casting method. When the cellulose ester is in the form of a multilayer, it also has a layer containing an ultraviolet absorber and a plasticizer, which may be a core layer, a surface layer, or both. Further, as a method of forming an uneven shape having an arithmetic mean roughness (Ra) of less than 50 to 100 nm on the surface of the transparent film substrate, for example, it is preferably formed by molding on a transparent film substrate. Continue to explain the melt casting film forming method. In the melt casting film forming method, a molding method in which a solvent (for example, methylene chloride or the like) is used, which is melt-cast by heating and melting, can be classified into a melt extrusion molding method, a pressure molding method, and a blow molding method in more detail. Method, injection molding method, air blowing method, extension molding method, and the like. Among them, a cellulose ester film having excellent mechanical strength, surface precision, and the like is preferably obtained by a melt extrusion method. An example of a melt extrusion method will be described, and a method for producing a cellulose ester film by a melt casting film formation method will be described. Fig. 1 is a schematic flow chart showing the overall configuration of a melt casting film forming apparatus for carrying out the method for producing a cellulose ester film of the present invention, and Fig. 2 is an enlarged view showing a portion of a cooling roll portion of the self-casting mold. 1 and 2, in the method for producing a cellulose ester film of the present invention, after a film material such as a cellulose resin is mixed, the film is extruded from the first cooling roll 5 by using an extruder 1' from the casting die 4. At the same time as the first cooling roll 5, a total of three cooling rolls in the order of the second cooling roll 7 and the third cooling roll-92-200904636 are externally cooled and solidified to form a film 10. Continuing, the film 10 is peeled off by the peeling roller 9, and then the both ends of the film are stretched by the stretching device 12 in the width direction, and then taken up by the winding device 16. Further, in order to correct the planarity, a contact roller 6 that presses the molten film on the surface of the first cooling roll 5 is provided. The contact roller 6 has elasticity on the surface and forms a nip between the first cooling roller 5. The contact roller 6 will be described in detail later. In the method for producing a cellulose ester film of the present invention, the conditions of melt extrusion can be carried out under the same conditions as those used for thermoplastic resins such as other polyesters. The material is preferably pre-dried. The moisture is dried to 100 ppm or less, preferably 200 ppm or less, by a vacuum or a vacuum dryer or a dehumidifying hot air dryer. The cellulose ester-based resin which is dried by hot air or under vacuum or under reduced pressure is used, for example, at an extrusion temperature of 2 0 0 to 300. (The melting is performed to the extent that it is filtered by the vane type filter 2 or the like to remove foreign matter. When the extruder is introduced into the extruder 1 by a supply hopper (not shown), oxygen is prevented under vacuum or under reduced pressure or under inert gas atmosphere. Further, it is preferable to prevent the oxidative decomposition or the like by the influence of moisture. When the additive such as a plasticizer is not previously mixed, the mixture can be kneaded in the middle of the extruder. The mixing device using the static agitator 3 or the like can be uniformly added. It is preferable to mix the cellulose resin with other additives such as stabilizers added as necessary, and it is preferred to mix the mixture before the melting. The cellulose resin and the stabilizer are preferably mixed initially. The mixing can be carried out using a mixer or the like. -93- 200904636 The above can also be mixed in the cellulose resin preparation process. When using a mixer, a v-type mixer, a conical spiral type mixer, a horizontal cylinder type mixer, a Henschel mixer, and a ribbon can be used. A general mixer such as a mixer. After mixing the film constituent materials as described above, the mixture can be directly melted using the extruder 1 to form a film, but once the film is formed After the granulation is carried out, the granules may be melted and formed into a film by the extruder 1. Further, when the film constituting material is a plurality of materials having different melting points, only at the temperature of the material having a lower melting point, once The so-called Mitong semi-molten is produced, and the semi-molten is put into the extruder 1 to form a film. When the film constituent material contains a material which is easily thermally decomposed, the pellet is not produced for the purpose of reducing the number of meltings. The method of directly forming a film, or the method of forming a film such as a semi-melt of Meton as described above is preferred. The extruder 1 can use various commercially available extruders, but melt-kneading and extruding the machine. Preferably, the single-axis extruder or the 2-axis extruder can be used. When the film-forming material is directly formed into a film without granules, it is preferable to use a 2-axis extruder because proper kneading degree is necessary. It can also be used as a film constituting material, such as a uniaxial extruder or a spiral having a spiral shape changed to a mixed type of Maddock type, Unimelt type, or Dulmage. 'When melted' can be used For the shaft press, a 2-axis extruder can also be used. The cooling step in the extruder 1 and after the extrusion can be replaced by an inert gas such as nitrogen or the oxygen concentration can be lowered by depressurization. The melting temperature of the film constituent material in the film is preferably -94-200904636 depending on the viscosity or discharge amount of the film constituent material, the thickness of the manufactured sheet, etc., but generally the glass transition temperature (Tg) of the film, 'Tg+l〇〇°c or less, preferably Tg+lOt: or more, Tg+ or less. The melt viscosity at the time of extrusion is 10 to 1 000 00 poise, preferably 10,000 poises, and the extruder 1 The retention time of the film constituent material in the film is short, preferably within 5 minutes, preferably within 3 minutes, more preferably within 2 minutes. The residence time is easily controlled by the type of extrusion machine 1 and the extrusion conditions are adjusted. The supply amount or L/D of the material, the number of spiral rotations, the spiral groove, etc. can shorten the residence time. The spiral shape or the number of rotations of the extruder 1 can be suitably selected by the viscosity or the amount of discharge of the film. The extruder 1 of the present invention has a breaking speed of 1 / sec to 1 0 0 0 / sec, preferably 5 / sec to 1 0 0 0 / sec, and is 10 / sec to 1 0 0 / sec. As the extruder 1 used in the present invention, a plasticizer can be generally used. The film constituent material extruded from the extruder 1 is sent to the casting 4, and is pressed into a film shape by the slit of the casting mold 4. The casting mold 4 is not particularly limited as long as it is used for producing a sheet or a film. Examples of the material of the casting mold 4 include hard chromium, chromium chromium carbide, titanium carbide, titanium carbonitride, titanium nitride, ultra-steel, ceramics (carbon, alumina, chromium oxide), or the like. For plating, as a surface, it is possible to use a grinding stone of less than 1000 stones for honing' plane cutting of more than 1 000 diamond grindstones (the cutting direction is perpendicular to the flow direction of the tree), and electrolytic honing , electrolytic composite honing and other processing (Tg 9 0 ° c 100 is a good clock, but better cutting by deep material forming mold can be, nitrided crane, grease, etc. -95- 200904636 cast molding The preferred material of the projection portion of the projection 4 is the same as that of the casting mold 4. Further, the surface precision of the projection portion is preferably 0.5 S or less, preferably 2 Å or less. The slit of the casting mold 4 is constituted. In order to adjust the interval, this is shown in Fig. 3. Among the pair of protrusions (1 ip ) forming the slit 3 2 of the casting mold 4, one of the pair of protrusions (3 ip ) having low rigidity and being easily deformed is 3 3, and the other side To fix the protrusion 34. Most of the heating bolts 35 are in the width direction of the casting mold 4, that is, the rectangular shape of the slit 3 2 Arranged at a constant pitch" Each of the heating bolts 35 is provided with a block 36 having a buried electric heater 37 and a cooling medium passage, and each of the heating bolts 35 extends longitudinally through each block 36. The base of the heating bolt 35 is fixed to the plastic The mold body 31 has a tip end that is connected to the outer surface of the flexible protrusion 3 3. The block 36 is cooled by a general air conditioner to increase or decrease the input force of the electric heater 37 and adjust the temperature of the block 36, thereby heating and contracting. The bolts 3 5 are used to adjust the thickness of the film by displacing the flexible protrusions 3 3 . A thickness gauge is provided at the desired flow after the molding, whereby the detected fabric thickness information is placed in the control device, and the thickness information is controlled. Comparing the device with the set thickness information, the power or operating rate of the heating element of the heating bolt can be controlled by a signal from the correction control amount of the same device. The heating bolt is preferably 20 to 40 cm in length and 7 to 14 mm in diameter, for example. Dozens of plural heating bolts are arranged at a preferred spacing of 20 to 40 mm. Instead of heating bolts, they can also be placed in the axial direction to manually move them back and forth to adjust the gap between the bolts as the main body. The gap adjusting member is generally adjusted to have a gap interval of 200 to 1 000 μm, preferably -96 to 200904636 300 to 800/zm, more preferably 400 to 600 μm. The first cooling roller 5~ The third cooling roll 8 is made of a seamless steel pipe having a thickness of 20 〜 and the surface is mirror-finished. The pipe of the internal coolant is configured to heat the film on the coolant roll flowing into the pipe. The contact roller 6 of the first cooling roller 5 is elastic, and is deformed along the surface of 5 by the pressure of the first cooling roller 5 to form a nip between the first roller 5. Fig. 4 is a schematic cross-sectional view showing an embodiment (hereinafter referred to as) of the touch roll 6. As shown in the figure, the contact roller A is a member in which the elastic roller 42 is disposed inside the sleeve 41. The metal sleeve 41 is made of stainless steel having a thickness of 0.3 mm. When the metal sleeve 41 is too thin, the strength is insufficient, and the elasticity is insufficient at the time. Therefore, it is preferable that the thickness of the metal sleeve 4 1 is 1.5 mm. The elastic roller 42 is provided with a rubber 44 formed on the surface of the inner cylinder 43 via the bearing rotation. When the contact roller A is pressurized on the first cooling roller 5, the metal sleeve 41 is pressurized by the first cooling roller 5, and the elastic roller 42 is similar to the first cooling roller 5, and the first cooling is performed. A nip is formed between the rolls. Cooling water 4 5 flows into the space formed between the metal sleeve 41 cylinders 4 2 . Fig. 5 and Fig. 6 show another embodiment B of the crimping rotor. The outer cylinder 51 having the flexibility of contact with the light B is made of seamless stainless steel (4 mm), and the inner side of the outer cylinder 51 is disposed at the same level as -3 mm, and the inflow is absorbed, and the surface thereof is in contact with the first cooling roller. Light A flexible metal, which can be reversely deformed to a thickness of 0.1~ free metal 'elastic roller 套管 sleeve 4 1 deformation, the internal contact of the contact roller in the elastic state (thickness The high-rigidity metal inner cylinder 52 is slightly configured. The cooling liquid 54 flows into the space 53 between the outer cylinder 51 and the inner cylinder 52. In detail, the contact roller B is a rotating shaft at both ends. The outer cylinder support flanges 56a and 56b are attached to the 55a and 55b, and the thin metal outer cylinder 51 is attached between the outer peripheral portions of the outer cylinder support flanges 56a and 56b. Further, the shaft is formed on the shaft of one of the rotation shafts 5a. The fluid supply tube 59 is disposed in the same axial center in the fluid discharge hole 58 of the fluid return passage 57 formed by the core, and the fluid supply tube 59 is connected and fixed to the shaft in the thin-walled metal outer cylinder 51. The fluid shaft cylinder 60 is disposed on the portion of the fluid shaft cylinder 60. The inner cylinder support flange 6 can be attached to both ends of the fluid shaft cylinder 60. 1a, 61b, from the outer peripheral portion of the inner cylinder supporting flange 61a' 61b to the other end side outer cylinder supporting flange 56b, a metal inner cylinder 52 having a wall thickness of about 15 to 20 mm is attached. Between 52 and the thin-walled metal outer cylinder 51, for example, a cooling liquid flow space 5 3 of about 10 mm is formed, and in the metal inner cylinder 5 2 , a communication flow space 53 and an inner cylinder support are formed in the vicinity of both end portions. The intermediate passages 6 2 a, 6 2 b of the outer side of the flanges 6 1 a, 6 1 b are outlets 5 2 a and the flow person □ 52b. Further, the outer cylinder 51 has flexibility similar to that of rubber elasticity. Flexibility, restorability, thinning in the range applicable to the theory of elastic wall thin-walled cylinders. The flexibility evaluated by the thin-walled cylinder theory is expressed by the ratio of wall thickness t/roller radius r, t/r The smaller the ratio, the higher the flexibility. In the contact roller B, when t/r S 0 · 0 3 , the flexibility is the optimum condition. The contact roller generally used is 'roller diameter: R = 200 to 500 mm (Roll-98- 200904636 Radius: r = R/2), roll effective width: L = 500~1600mm, ratio of roll radius r / roll effective width L: r / L <1, its horizontally long shape. As shown in Fig. 6, 'for example, roll diameter: R = 3〇〇mm, roll effective width: L=1 200mm' wall thickness: the optimum range of t is 15〇x〇.〇3=4.5mm or less' but for melting When the sheet width is 13 〇〇mm, when the average line pressure is 9 8 N/cm, the same as the rubber roller of the same shape, the rebound ratio is equal when the wall thickness of the outer cylinder 51 is 3 mm, and the outer cylinder 51 is The nip width k of the nip of the chill roll is also about 9 mni, and the light nip width of the rubber is close to about 12 mm, and it can be pinched under the same conditions. And the amount of rubbing in the width k of the nip is 〇.〇5~O.lmin. Among them, as 〇1^0.03, when the roll diameter is generally 11=200 to 500111111, particularly in the range of 2 mm S t S 5 mm, sufficient flexibility can be obtained, and it is easy to be thinned by machining. Implementation has become a very practical range. When the wall thickness is 2 mm or less, the elastic deformation during processing cannot be processed with high precision. The conversion 値 is 0.008$t/rS0.05 for the normal roll diameter, but it is practically based on the t/r = 0.03, which is proportional to the roll diameter and the wall thickness is also increased. For example, the roll diameter: R = 200, t = 2~3mm' light path: R = 500, t = 4~5mm range. The contact lightes A and B are supplied to the first cooling roll by an energizing means (not shown). The supply capacity of the energy supply means is F, and the width W of the film of the nip along the rotation axis direction of the first cooling roll 5 is set to 9.8 = F / W (linear pressure) is set to 9.8 - 1 4 7N/cm ° -99- 200904636 In the present invention, a nip is formed between the contact rolls A, B and the first cooling roll 5, and the nip is corrected to be planar between the passage of the film. Therefore, when the contact roller is composed of a rigid body and the nip is not formed between the first cooling roller, the film is nip for a long time under a small linear pressure, so that the planarity can be more reliably corrected. That is, if the line pressure is less than 9.8 N/cm, the plastic film line cannot be sufficiently eliminated. On the contrary, when the line pressure is larger than 147 N/cm, the film does not easily pass through the nip, and the film thickness is liable to cause unevenness. Further, when the surfaces of the contact rolls A and B are made of metal, the surface of the rolls A and B can be smoothly smoothed compared with the case where the surface of the contact roll is made of rubber, so that a film having high smoothness can be obtained. Further, as the material of the elastic body 44 of the elastic roller 42, an ethylene-propylene propylene rubber, a neoprene rubber, a ruthenium rubber or the like can be used. It is important to eliminate the plastic film line by the contact roller 6, and it is important that the film viscosity when the contact roller 6 is pressed against the film must be an appropriate range. Further, it is known that cellulose esters have a large change in viscosity due to temperature. Therefore, in order to set the viscosity when the contact roll 6 is pressed against the cellulose ester film to an appropriate range, it is important that the film temperature at the time of the contact of the contact lens 6 with the cellulose ester film is set to an appropriate range. When the glass transition temperature of the cellulose ester film is (Tg), the film is pressed against the film temperature T before the contact roll 6 to satisfy Tg. < T < Tg + 1 l 〇 ° C conditions are preferred. If the film temperature T is lower than Tg, the film viscosity will be too high to correct the film line. Conversely, if the temperature T of the film is higher than Tg + 110, the surface of the film -100-200904636 cannot be uniformly adhered to the roll, and the film line cannot be corrected. Preferably Tg + lot: < T < Tg + 9 (TC, more preferably Tg + 2 (TC < T <Tg+70〇co The film temperature at which the contact lens 6 is pressed with the cellulose ester film is set to an appropriate range, and the melt extruded from the casting die 4 is adjusted by the position p1 in contact with the first cooling roll 5. The length of the first cooling roll 5 along the nip of the first cooling roll 5 and the contact roll 6 is L: the preferred material of the first roll 5 and the second roll 6 is carbon. Steel, stainless steel, resin, etc. Further, the surface precision is preferably high, and the surface roughness is 0.3 S or less, preferably 〇.〇is or less. By reducing the portion of the opening portion (1 i p ) of the casting mold 4 to the first roller 5 to 70 kPa or less, the effect of correcting the plastic film line can be increased. Preferably, the reduced pressure is 50 to 70 kPa. The method of maintaining the partial pressure of the opening from the opening of the casting die 4 to the first roller 5 to 70 kPa or less is not particularly limited, and the self-casting mold 4 is applied to the periphery of the roller to cover the pressure member, and the pressure is reduced. method. At this time, it is preferable that the suction device is disposed so that the device does not become a place where the sublimate is attached, and the heater is applied to perform heating or the like. If the suction pressure is too small, the sublimate material cannot be effectively attracted. Therefore, it is necessary to have a suitable suction pressure to melt the film-like cellulose ester resin from the T mold 4 to the first roll (the first cooling roll). 5, the second cooling roll 7 and the third cooling roll 8 are sequentially conveyed in a dense manner and cooled and solidified to obtain an unextended -101 - 200904636 cellulose ester-based resin film 10. In the embodiment of the present invention as shown in Fig. 1, the cooled and solidified unstretched film 1 which is peeled off from the third cooling roll 8 by the peeling roller 9 is introduced into the stretching machine via a dancer roll (film tension adjusting roll). 12. Here, the film 1〇 is oriented in the lateral direction (width direction). By this extension, the molecules in the film are aligned. A method of extending the film in the width direction can be carried out by a known tenter or the like. On the one hand, the transmission axis of the polarizing film is generally also in the width direction. The polarizing plate of the polarizing film is parallel to the retardation axis of the optical film, and the laminated polarizing plate is incorporated in the liquid crystal display device, thereby improving the display contrast of the liquid crystal display device and obtaining a good viewing angle. The glass transition temperature (Tg) of the film constituent material can be controlled by the difference in the kind of the material constituting the film and the ratio of the materials constituting the film. When a retardation film is produced as a cellulose ester film, the Tg is 1 20 ° C or more, preferably 1 35 ° C or more. In the liquid crystal display device, in the developing state of the image, the temperature of the device itself rises, for example, the temperature rise from the light source causes the temperature environment of the film to change. At this time, when the Tg of the film is lower than the ambient temperature of the film, the stagnation caused by the state of the molecular orientation fixed to the inside of the film and the size of the film are greatly changed. When the Tg of the film is too high, the temperature at which the film constituent material is thinned is too high, and the energy consumption for heating is increased, and the material itself is decomposed when the film is formed, and coloring is caused thereby, so Tg is 25 0 Below °c is preferred. Further, in the extending step, known heat setting conditions, cooling, and relaxation treatment can be carried out, and those having characteristics required for the intended optical film can be appropriately selected. The function of the retardation film when the physical properties of the retardation film and the viewing angle of the liquid crystal display device are to be expanded can be appropriately selected by the above-described stretching step and heat setting treatment. In the case where the stretching step and the heat setting treatment are carried out, the heating and pressurizing step is performed before the stretching step and the heat setting treatment. In the case of producing a retardation film as a cellulose ester film, and the function of the composite cellulose ester film, it is necessary to perform refractive index control, but the refractive index control can be carried out by an extending operation, which is a preferred method. The extension method will be described below. In the step of extending the retardation film, the length of the cellulose resin is extended by 1.0 to 2.0 times in the direction of the cellulose resin, and when the film is extended in the direction perpendicular to the film by 1.0 to 1 to 2.5 times, the necessary retention time Ro can be controlled. Rt, or can improve the planarity. Here, Ro is the in-plane retention enthalpy, which is the difference between the refractive index of the in-plane long-direction MD and the refractive index of the width direction TD multiplied by the thickness, and Rt is the display thickness direction retention 値, which is the in-plane refraction. The difference between the ratio (the average of the long direction MD and the width direction TD) and the refractive index in the thickness direction is multiplied by the thickness. The stretching may be carried out, for example, in the longitudinal direction of the film and in the direction orthogonal to the film surface, i.e., in the width direction, sequentially or simultaneously. At this time, when the stretching ratio in at least one direction is too small, a sufficient phase difference cannot be obtained, and when it is too large, it is difficult to extend and the film is likely to be broken. -103- 200904636 An effective method of extending the refractive index nx, ny, and nz of the film in a predetermined range in the two-axis direction orthogonal to each other. Here, nx represents the refractive index of the long-hand MD direction, ny represents the refractive index in the wide TD direction, and nz represents the refractive index in the thickness direction. For example, when extending in the direction of melt casting, if the shrinkage in the width direction is too large, the nz is too large. At this time, it is suppressed that the width of the film is shrunk or extended in the width direction. When extending in the width direction, uneven distribution of refractive index occurs in the width direction. This distribution sometimes occurs when the tenter method is used, and it is presumed that when the film is stretched in the width direction, a contraction force is generated in the central portion of the film, and the end portion is fixed, which causes a so-called bowing. phenomenon. At this time, when the stretching is also performed in the casting direction, the bowing phenomenon can be suppressed, and the uneven distribution of the phase difference in the width direction can be reduced. By extending in the two-axis directions parallel to each other, the film thickness variation of the obtained film can be reduced. When the film thickness of the retardation film is excessively changed, the phase difference is uneven, and when used in a liquid crystal display, unevenness in coloring or the like may occur. The film thickness variation of the cellulose ester film is ±3%, more preferably ±1%. In the above object, the method of extending in the two-axis direction orthogonal to each other is effective, and the stretching ratio in the two-axis direction orthogonal to each other is 1.0 to 2.0 times in the final casting direction, and 1.01 to 2.5 times in the width direction. The range is preferably, and it is more preferable to obtain a residence enthalpy which is required to be in the range of 1.0 to 1.2 times in the casting direction and 1.05 to 2.0 times in the width direction. When there is an absorption axis of a polarizer in the long direction, the transmission axis of the -104-200904636 photon in the width direction is uniform. In order to obtain a long-length polarizing plate, it is preferable that the retardation film is stretched in the width direction to obtain a slow phase axis. When a cellulose ester obtained by positive birefringence is used as the stress, when the above structure is extended in the width direction, the retardation axis of the retardation film can impart stress in the width direction. In this case, in order to improve the display quality, the retardation axis of the retardation film is preferably in the width direction, and the retention of the target must be satisfied, and the formula: (the stretching ratio in the width direction) > (the stretching ratio in the casting direction) condition. After the extension, the end portion of the film is cut by the slitting machine 13 as a slit of the width of the product, and then the flange processing is performed by the edge ring 14 and the back roller 15, and the edge processing is performed on both ends of the film. (knurled, embossing), being taken up by a winder 16 to prevent the occurrence of sticking or scratching in the cellulose ester film (element) F. The method of burring processing can process a metal ring having a convex-concave pattern on its side by heating or pressurizing. Further, the holding portion of the press plate at both end portions of the film is generally deformed and cannot be used as a film product, so that it can be reused as a raw material after being cut. Continuing, the film winding step is such that the film is wound on the take-up reel by keeping the shortest distance between the outer peripheral surface of the cylindrical roll film and the outer peripheral surface of the previous movable transfer roll. Further, before the take-up reel, means such as a static eliminating fan for removing or reducing the surface potential of the film may be provided. The coiler for producing the cellulose ester film of the present invention can be wound by a general user's winding method such as a constant tension method, a constant torque method, a tilting tension method, or a program tension control method with a constant internal stress. Further, the initial winding tension at the time of winding the fiber-105-200904636 velocide film is preferably 90.2 to 3 00.8 N/m. In the winding step of the film, it is preferable to wind up the film under the environmental conditions of a temperature of 20 to 30 ° C and a humidity of 20 to 60 % RH. By setting the temperature and humidity of the film winding step in this way, the humidity resistance change in the thickness direction retention enthalpy (Rt) can be improved. When the temperature in the winding step is less than 20 °C, crepe is generated, and the deterioration of the quality of the film roll makes it impossible to use it. When the temperature in the winding step of the film exceeds 30 °C, wrinkles are still generated, and the film roll quality is deteriorated, which is not practical. Further, if the humidity in the winding step of the film is less than 20% RH, static electricity is easily generated, and deterioration of the quality of the film roll makes it impossible to use it. When the humidity in the winding step of the film exceeds 60% RH, the roll quality, the bonding failure, the conveyability, and the like may be deteriorated. When the cellulose ester film is wound into a roll shape, the core of the roll may be only the core on the cylinder, and may be any material, but it is preferably a hollow plastic core as a plastic material to be resistant. The heat-resistant plastic material having a heat treatment temperature may be a resin such as a phenol resin, a xylene resin, a melamine resin, a polyester resin or an epoxy resin. Further, it is preferable to use a tempered thermosetting resin such as glass enamel. For example, a hollow plastic core: a roll core having an outer diameter of 6 inches (hereinafter referred to as '2.5 inches) and an inner diameter of 5 inches using FRP. For the number of rolls of these volume cores, it is preferable to use 1 roll or more, and 5 roll or more is better. The roll thickness is preferably 5 cm or more, and the length is 5 00 to 1 0000 m -106 to 200904636, and the film width is 1 ~5m is good 'extra good for 1.5~4m. When a wide film is produced, it is also possible to apply a slit to the film before winding to obtain 2 to 3 roll films. In the film forming step, the platen holding portion at both ends of the cut film is pulverized or, if necessary, granulated, and can be reused as a raw material for a film of the same type or a film material of a different type. The surface treatment of the anti-glare layer may use a washing method, an alkali treatment method, a surface plasma treatment method, a high-frequency discharge plasma method 'electron beam method, an ion beam method, a sputtering method, an acid treatment, a corona treatment method, Atmospheric piezoelectric slurry method, etc. Here, the corona treatment is carried out by applying a high voltage of 1 kV or more to the electrodes under atmospheric pressure, and performing the treatment under discharge, and can be carried out using a device sold by Kasuga Electric Co., Ltd. or Toyo Electric Co., Ltd. The intensity of the corona discharge treatment depends on the distance between the electrodes, the output per unit area, and the frequency of the generator. A commercially available product may be used for one electrode (A electrode) of the corona treatment device, but the material may be selected from aluminum, stainless steel, or the like. The other is an electrode (B electrode) to enclose the plastic film, and the light electrode to be placed at a certain distance from the A electrode to be subjected to corona treatment can be stabilized and uniformly performed. This can also be used as a lining roller for ceramics, polyoxyalkylene, EP T rubber, Heplon rubber, etc. on rollers made of Ming, stainless steel, and their metals. It is better. The frequency used for the corona treatment is 20 to 100 kHz, and the frequency is preferably 30 to 60 kHz. When the number of frequencies is lowered, the uniformity of corona treatment is deteriorated, and corona treatment is uneven. Further, when the number of frequencies is too large, there is no particular problem in performing corona treatment with high output. However, when the corona treatment of the low-transmission -107-200904636 is performed, it is difficult to perform the stabilization process, and as a result, processing unevenness occurs. The output of the corona treatment is 1~5w_min./m2, and the output of 2~4wmin./m2 is preferred. The distance between the electrode and the film is 5 to 50 mm, but preferably 10 to 35 mm. When the gap is too open, it is necessary to maintain a certain output and must have a high voltage, which is prone to unevenness. Also, when the gap is too narrow, the applied voltage is too low, and unevenness is likely to occur. In addition, when the film is continuously processed, the film is in contact with the film to cause scratches. Further, as the alkali treatment method, only the film to which the antiglare layer is applied is immersed in the aqueous alkali solution, and is not particularly limited. As the aqueous alkali solution, an aqueous sodium hydroxide solution, a potassium hydroxide aqueous solution, an aqueous solution or the like can be used, and among them, an aqueous sodium hydroxide solution is also preferred. The alkali concentration of the aqueous alkali solution, for example, the concentration of sodium hydroxide is preferably 0.1 to 25% by mass, preferably 0.5 to 15% by mass. The alkali treatment temperature is usually 10 to 80 ° C, preferably 20 to 60 t:. The alkali treatment time is from 5 seconds to 5 minutes, preferably from 30 seconds to 3 minutes. After the treated film is neutralized with acidic water, it is preferred to wash the sulfur sufficiently. In the present invention, at a high pressure or a pressure close to this, a high frequency voltage of 50 kHz to 150 MHz is applied between the opposing electrodes to form a discharge 'the excited gas formed by the discharge, and the transparent film substrate or the transparent film substrate After the surface of the film having the anti-glare layer on the film substrate is contacted, it is preferable to form the film after the anti-amplitude layer is formed. The frequency is preferably 50 kHz to 27 MHz. The counter electrode is composed of the first electrode and the second electrode, and the frequency of the high frequency voltage applied to the pole of any one of -108-200904636 is preferably 50 kHz to 150 MHz. Further, the frequency of the high frequency voltage applied to the first electrode is 1 to 200 kHz, and the frequency of the high frequency voltage applied to the second electrode is preferably 800 kHz to 1 50 MHz. The plasma discharge treatment at atmospheric pressure or near this pressure is hereinafter referred to simply as the atmospheric piezoelectric slurry method. a film having an anti-glare layer on a transparent film substrate, and a voltage of the first frequency number ωΐ is applied to the first electrode between the opposing electrodes formed by the first electrode and the second electrode at or near atmospheric pressure a high frequency voltage of the component is applied to the second electrode by a high frequency voltage of a voltage component of the second frequency number ω2 to form a discharge, and after the excited gas formed by the discharge is in contact with the surface of the transparent film substrate, An antireflection layer is formed on the upper surface. As an atmospheric piezoelectric slurry method, reference is made to Japanese Laid-Open Patent Publication No. Hei No. 1 1 - 1 3 3 205, Japanese Patent Publication No. 2000-180, and Japanese Patent Publication No. Hei 1 1 - 6 1 4 0 6 The technique disclosed in Japanese Laid-Open Patent Publication No. 2000- 1472, No. 2000-121, and the like. Continue to explain the atmospheric piezoelectric slurry method. At atmospheric pressure or near the pressure, a gas is supplied to the discharge space (between the opposing electrodes), and a high frequency voltage is applied to the discharge space to cause the gas to be excited to become a plasma state. In the gas of the agitated plasma state, Exposure to a film surface having an anti-glare layer on a transparent film substrate. The high frequency voltage applied to the discharge space formed between the opposing electrodes may be a high frequency of one frequency, or may be a high frequency of two or more frequency numbers. The atmospheric piezoelectric slurry treatment is carried out at atmospheric pressure or near this pressure, -109- 200904636, but the atmospheric pressure or the pressure close to this is 20 to 110 kPa, preferably 93 to 1 04 kPa. The gas supplied between the opposing electrodes (discharge space) is at least containing a stimulating gas excited by a high frequency voltage, or a stimulating gas excited by a high frequency voltage, and receiving the energy to become a plasma state or A gas that stirs up the state. The high frequency rate is a frequency having at least 0.5 kHz. When plasma discharge treatment is performed at a high frequency voltage of one frequency (sometimes referred to as a high frequency and high frequency voltage addition method), or when a plasma discharge treatment is performed at a high frequency voltage of two frequency numbers (sometimes The electrodes called 2 frequency number and high frequency voltage addition method are used in the same way, and the device itself does not have much difference. The difference is that there are two high-frequency power sources, and there is a filter attached thereto, and a high frequency voltage is applied from the electrodes of the opposite electrodes. 1 When the frequency is high and the frequency is applied, one of the opposing electrodes is the ground electrode, and the other is the external electrode. The high frequency power is connected to the applied electrode, and the ground is grounded on the ground electrode. Referring to Fig. 7, a thin film forming apparatus (atmospheric piezoelectric slurry processing apparatus) of each of the first frequency number high frequency voltage addition method and the two frequency number high frequency voltage addition method will be described. Fig. 7 is a schematic view showing an example of a film forming apparatus of a high frequency and high frequency voltage application method. In the same figure, an external electrode (corner type electrode) 136 having a high frequency voltage inside the plasma discharge vessel 130 is formed, and a roll type ground electrode 1 3 5 which winds the lower transparent film substrate F is formed. Relative electrode. How many of the additional electrodes 136 can be juxtaposed. The gas G is supplied from the gas supply port 152 of the plasma discharge vessel 1 by a -110-200904636 sieve which homogenizes the gas G, along the applied electrode 136, and the external electrode and the plasma discharge vessel The inner wall of 1 3 1 passes, so that the discharge space 1 3 between the opposing electrodes is sufficient for the gas G. The high frequency power supply 21 is applied to the external electrode 136 to apply a high frequency voltage, and the transparent film substrate F is exposed to the gas G excited by the discharge space 132. The frequency of the applied high frequency voltage is preferably 50 kHz or more. It is preferably in the range of 50 kHz to 150 MHz, which is preferable from the viewpoint of uniform processing or large-area processing. The transparent film substrate F is exposed between the agitated gas G, and the electrode can be heated or cooled by the electrode temperature adjusting means 160. As the medium for temperature adjustment, an insulating material such as distilled water or oil can be preferably used. In the plasma discharge treatment, it is desirable to avoid uneven temperature of the substrate in the wide direction or the long direction as much as possible, and the temperature inside the electrode can be uniformly adjusted. Fig. 8 is a schematic view showing another example of a film forming apparatus in which the frequency is not the same as the frequency and voltage. In the same manner as in the case of FIG. 7, the transparent film substrate F is plasma-discharged by the roll electrode (first electrode) 135 and the opposing electrode (discharge space) 1 32 of the corner-type electrode group (second electrode) 136. Processor. In the discharge space (between the electrodes) 132 between the roller electrode (first electrode) 135 and the corner electrode group (second electrode) 136, the number of frequencies applied to the first electrode 141 by the roller electrode (first electrode) 135 The high frequency voltage VI of ω 又 is formed by the high frequency voltage V2 of the second power source 142 plus the frequency number ω2 in the corner electrode group (second electrode) 136. Between the roller electrode (first electrode) 135 and the second power source 141, a first filter 143 is provided to allow a current from the i-th power source i 4 to flow into the roller electrode (first -111 - 200904636 electrode) 135. The filter 143 is designed such that the current from the first power source 141 is difficult to pass, and the current from the second power source 142 is easily designed. Further, between the corner-shaped electrode group (second electrode) 136 and the second power source 142, the second filter 144 is provided to allow a current from the second power source to flow into the second electrode, and the second filter 144 is designed to be self-contained. 2 The current of the power source 142 is difficult to pass, and the current from the first power source 141 easily passes. Among them, it is difficult to pass the current, and it is preferably only 20% or less of the current, and preferably only 10% or less. On the other hand, the so-called easy passage is preferably 80% or more of the passing current, more preferably 90% or more. For example, a capacitor of a number of 〇 to tens of thousands of pF or a number of coils can be used in accordance with the number of frequencies of the second power source 142. As the second filter 1 44 'corresponding to the frequency of the first power source 14 1 , a wire i of i 〇 μ η or more is used, and the wire 圏 or the capacitor can be grounded via the wire, and can be used as a furnace. The light electrode 135 is used as the table 2 electrode, and the corner tube type electrode group 136 can be used as the first electrode. The second power source is connected to the first electrode and the second power source is connected to the second electrode. Further, the "th power supply" has a force gp which can only add a local frequency voltage (Vl > V2) larger than the second power supply. Also, only have the frequency number ω1 < ω2 ability can be. In Fig. 8, the gas G generated by the gas supply device 15 of the gas supply means 150 is introduced into the electric discharge discharge processing vessel 131 by the gas supply port 152 at a controlled flow rate. The discharge space 132 and the plasma discharge treatment container 131 are filled with the gas G. The transparent film substrate F is unwound from a not-shown element, and then conveyed to -112-200904636, or conveyed by the previous step, and nip by the nip roller 165 via the guide roller 164 to block the transparent film substrate. The air or the like is transferred between the roll electrode 135 and the roll electrode 135, and is transferred between the roll electrode type electrode group 136 and the roll electrode (first electrode) 135 and the corner tube type electrode group (second electrode) 136. The voltage generates a discharge plasma with a relative electrode (discharge space) of 132. The transparent film substrate F is a gas which is wound while being in contact with the roller electrode 135 while being exposed to the plasma state. The transparent film substrate F is taken up by a winder (not shown) via a nip roll 166 and a guide roll 167, or transferred to a secondary step. The discharge body G' is discharged through the exhaust port 153. In the exposure time of the gas in the plasma state, the roller electrode (first electrode) 135 and the corner tube electrode group (second electrode) 136 are heated or cooled, and the temperature is adjusted by the electrode temperature adjusting means 160 to send the medium. The liquid pump P is sent to the two electrodes via the pipe 161, and the temperature is adjusted from the inside of the electrode. Moreover, the 1 6 5 and 1 6 6 are the pulse wave of the cutting plasma discharge treatment vessel 133 and the cutting plate of the outside, and the pulse wave of the intermittent mode or the continuous wave of the signal wave, although not limited The voltage waveform, but it is better to add high energy and high frequency voltage to form a strong film. The frequency of the high frequency voltage applied to the first electrode is 1 to 200 kHz, and the frequency of the high frequency voltage applied to the second electrode is preferably 800 kHz or more. The power density at this time is preferably 1 to 50 W/cm 2 (wherein the cm 2 of the denominator is the area caused by the discharge), preferably 1.2 to 30 W/cm 2 . -113- 200904636 As a high-frequency power supply, 100 kHz; |!

And * printed as Hay den Research Institute Impulse high frequency power supply (continuous mode is 100 kHz). Fig. 9 is a perspective view showing an example of a conductive metal base material of a roll electrode and a structure covered with a dielectric. In the same figure, the roller electrode 1 3 5 a is a conductive metal base material 1 3 5 A, and is covered with a dielectric body 135B. The interior becomes a hollow jacket that is temperature-adjustable. Fig. 10 is a perspective view showing an example of a conductive metal base material of the corner tube type electrode shown in Fig. 7 and Fig. 8 and a structure covered with a dielectric body. In Fig. 10, the corner electrode 136a has a dielectric body 136B which is the same as the case of Fig. 9 for the conductive metal base material 136A, and the structure of the electrode is a metal pump, which becomes The jacket can be used for temperature regulation during discharge. Further, the number of the corner-type electrodes is such that a plurality of roots are provided along a circumference larger than the circumference of the above-mentioned roller electrode, and the discharge area of the electrode is the area sum of the full-bore cylindrical electrode faces of the roller electrode 135. The corner tube electrode 136a shown in Fig. 10 may be a cylindrical electrode. However, the angle tube type electrode has an effect of expanding the discharge range (discharge area) as compared with the cylindrical electrode, and is therefore suitable for use in the present invention. In Fig. 9 and Fig. 10, each of the roller electrode 135a and the corner-tube electrode 136a is made of a conductive metal base material 135A and 136A, and a ceramic material is used as the dielectric bodies 135B and 136B, and an inorganic compound is used.

As the ceramic material used for the dissolution, an alumina, a tantalum nitride, or the like can be used, and among them, alumina is particularly preferable because it is easy to process. Further, the dielectric layer may be a liner-treated dielectric material provided with a glass liner. Examples of the conductive metal base materials 13 5A and 13 6A include titanium or a titanium alloy, a metal such as silver, platinum, stainless steel, aluminum, or iron, or a composite material of iron and ceramics or a composite of aluminum and ceramics. Material, but titanium or titanium alloy is particularly preferable from the following reasons. The distance between the two electrodes (electrode gap) can be determined in consideration of the thickness of the dielectric body provided on the conductive metal base material, the magnitude of the applied voltage, the purpose of the plasma, etc., but when the dielectric body is provided on the electrode side. The shortest distance between the surface of the dielectric body and the surface of the conductive metal base material, and the distance between the dielectric bodies when the dielectric is provided on both of the electrodes, and in any case, from the viewpoint of uniform discharge, 0.1~ 20mm is preferred, and particularly preferably 0.5 to 2mm. The plasma discharge treatment container is preferably a Pyr ex (registered trademark) glass processing container, but may be insulated from the electrode, and may be made of metal. For example, a polyimide or the like may be bonded to the inner surface of aluminum or stainless steel, or the metal surface may be insulated without being sprayed with a ceramic. The conductive metal base material and the dielectric body will be described in detail. The electrodes used in the atmospheric piezoelectric slurry method must be structurally or in a manner that can withstand severe conditions. As such an electrode, it is preferable to cover the dielectric body on the metal base material -115-200904636.

The alloy is particularly good. When the metal base material is used as titanium or titanium alloy, the dielectric can be used as described above. Avoid the deterioration of the electrode during use, especially avoiding cracking, peeling, falling off, etc., and can withstand long-term use under severe conditions. The metal base material of the electrode is a titanium alloy containing 70% by mass or more of titanium or Titanium. The specific characteristics of the dielectric material are preferably inorganic compounds having a specific electric conductivity of 6 to 4 5 , and examples of such a dielectric material include ceramics such as alumina and tantalum nitride, or tannic acid. A glass lining material such as a salt glass or a borate glass, etc., in which a ceramic device to be described later is sprayed or a glass lining is preferred. A dielectric body provided after the molten alumina is preferably used. The dielectric material has a void ratio of 10% by volume or less, preferably 8% by volume or less, preferably more than 5% by volume, and 5% by volume or less, and a gap of a dielectric body. The rate can be measured by a BET sorption method or a mercury porosimeter. For example, a porosity can be measured by using a mercury porosimeter manufactured by Shimadzu Corporation using a dielectric body coated with a metal base material to measure the void ratio. High durability due to lower void ratio For the dielectric material having a low void ratio, a high-density, high-density ceramic spray coating film or the like by atmospheric plasma spray method, etc., may be used, and the void ratio is further reduced. In the atmospheric plasma spray method, a fine powder such as a ceramics or a wire is placed in a plasma heat source, and the particles in a molten or semi-molten state are blown and adhered to a metal base material to be coated. -117- 200904636 The so-called plasma heat source is to make the molecular gas high temperature and dissociate into atoms' and then give energy to emit electrons into high-temperature plasma gas. The plasma gas has a high jet velocity. Compared with the past arc spraying or surface spraying, the molten material can be punched into the metal base material at a high speed, so that the adhesion strength is high, and a high-density coating can be obtained. For more details, a method of spraying a heat-shielding film by a high-temperature exposed member described in JP-A-2000-301655 can be referred to. By this method, the void ratio of the dielectric (ceramic spray film) coated as described above can be obtained. Further, as another preferable form for resisting large electric power, the thickness of the dielectric body is 〇·5 to 3 mm. The film thickness variation is preferably 5% or less, preferably 3% or less, more preferably 1% or less. In order to further reduce the void ratio of the dielectric body, it is preferable to further perform the sealing treatment of the inorganic compound on the spray film such as the above ceramics. Here, as the inorganic compound, a metal oxide is preferable, and cerium oxide (S i Ο X ) is contained as a main component. The inorganic compound to be subjected to the plugging treatment is preferably formed by hardening by a sol-gel reaction. When the inorganic compound of the plugging treatment is a metal oxide as a main component, a metal alkoxide or the like is applied as a plugging liquid to the ceramic spray film, and is cured by a sol-gel reaction. When the inorganic compound contains cerium oxide as a main component, it is preferred to use alkoxy decane as a sealing liquid. Among them, in the promotion of the sol-gel reaction, energy treatment is preferred. As the energy treatment, there is thermal curing (preferably 2 〇 〇 r or less), or ultraviolet irradiation. Further, as a method of sealing the pores, the sealing liquid can be diluted and the coating and hardening are repeated several times, and the inorganicization can be further improved to obtain a dense electrode having less deterioration from -118 to 200904636. When a metal alkoxide or the like of a dielectric-coated electrode is used as a sealing liquid and applied to a ceramic spray film, and the sealing treatment is performed by a sol-gel reaction, the content of the metal oxide after curing is 60% or more are preferred. When alkoxysilane is used as the metal alkoxide of the plugging liquid, the content of Si Ox (X is 2 or less) after curing is preferably 60 mol% or more. The SiOx content after hardening was measured by xpS analysis of the cross section of the dielectric layer. In the present invention, the maximum height (Rmax) of the surface roughness specified by Jis B 0601:2001 is adjusted to at least 1 〇//m on the surface at least in contact with the substrate of the electrode, and the viewpoint of the effect described in the present invention is obtained. Preferably, the maximum roughness of the surface roughness is 8 #m or less, and particularly preferably 7 // m or less. By performing the honing of the surface of the dielectric body of the dielectric-coated electrode in this manner, it is possible to maintain a certain dielectric thickness and the interval between the electrodes, thereby stabilizing the discharge state without being inferior in heat shrinkage or Residual stress causes it to deform or crack. 'High durability can be greatly improved. The honing of the surface of the dielectric body is preferably carried out in a dielectric body on the side at least in contact with the substrate. Further, the arithmetic mean roughness (Ra) prescribed by JIS B 060 1 ·· 200 1 is preferably 0.5/zm or less, more preferably less than or equal to i.m. In the dielectric-coated electrode used in the present invention, as another preferable form which can withstand a large electric power, the heat-resistant temperature is 1 〇 〇. (3 or more. More preferably 120 ° C or more 'extra is 150 ° C or more. The upper limit is 500. (:. and 'The so-called heat-resistant temperature is not caused by insulation damage, can withstand normal discharge -119- 200904636 The highest temperature in the state of electricity. The heat-resistant temperature can be applied to the dielectric of the above-mentioned ceramics, or the dielectric layer of the laminated glass lining which is mixed in a different amount, or can be appropriately combined and selected from the following metal base materials and In the present invention, it is necessary to use an electrode which can maintain a uniform luminescent discharge state under such a voltage in the plasma discharge treatment device. In the present invention, the electric power is applied between the opposite electrodes. The second electrode is supplied with a power density of 1 to 50 W/cm 2 , preferably 1.2 to 30 W/cm 2 , and a discharge gas is generated to generate a plasma, and energy is supplied to the film forming gas to form a film. In addition, a continuous-wave continuous oscillation mode called continuous mode and an intermittent vibration mode in which ΟΝ/OFF is intermittently called a pulse mode may be employed, but at least the second electrode side is connected The signal wave method is preferably a dense and good film. The discharge condition is such that a high frequency voltage is applied to the discharge space of the first electrode and the second electrode, and the high frequency voltage has at least a first frequency number ω overlapping. It is preferable that the voltage component and the voltage component of the second frequency number ω2 which is higher than the first frequency number are formed. The high frequency voltage is a voltage component in which the first frequency number ω 重叠 is superimposed, and the first frequency number is overlapped. Ωΐ is also a component of the voltage component of the second frequency number ω2, and the waveform is the signal wave of the frequency number ω1, and the signal of the frequency number ω2 which is higher than this is the signal waveform of ω1. The waveform of the wave is not limited, and may be a pulse wave for both sides, or one of the signal waves and the other is a pulse wave. Further, the third voltage may be further divided into -120 to 200904636. However, the present invention In the same manner as the high frequency and voltage application method of the first frequency, the film can be densely formed at least on the second electrode side. The discharge starting voltage is the actual discharge space (the composition of the electrodes). The minimum voltage at which the discharge can be caused by the reaction conditions (gas conditions, etc.). The discharge start voltage can be slightly changed by the type of the gas supplied to the discharge space or the type of the electrode, but it can be considered and discharged. The discharge voltage of the gas alone is slightly the same. It is presumed that the high frequency voltage is applied to the opposite electrode (discharge space) as described above, which can cause discharge and generate high-density plasma. The specific method of adding high frequency voltage to the discharge space can be used. The first electrode constituting the counter electrode is connected to the first power source having the frequency ω1 and the first high frequency voltage of the voltage VI, and the second electrode is connected to the second high frequency voltage of the frequency ω2 and the voltage V2. 2 power film forming device (atmospheric piezoelectric slurry processing device). When the high frequency voltage is applied from the two high-frequency power sources, S is necessary to start the discharge of the discharge gas having the higher discharge start voltage on the first frequency number ωΐ side, and the second frequency number ω2 side is used to increase the power. It is necessary to focus on the density of the pulp to form a dense and good film. It is preferable to apply a high-frequency voltage of about 1 to 200 kHz from the first electrode to the first power source, and to apply a high-frequency voltage of about 800 kHz to 15 MHz from the second electrode using the second power supply. At this time, by adding it! The high frequency voltage of ~ 00 kHz can excite the discharge gas with a higher discharge start voltage to generate plasma. -121 - 200904636 Further, it is preferable that the first power source has a capability of applying a higher frequency voltage than the second power source. Further, as a discharge condition, a high frequency voltage is applied between the first electrode and the second electrode, and the high frequency voltage is a superimposed i-th high frequency voltage: VI and a second high frequency voltage: V2, and the discharge start voltage is applied. When IV, V12IV>V2 or Vl>IVgV2 is satisfied. Better to meet VI > IV > V2. The definition of the local frequency and the discharge start voltage, and the specific method of applying the high frequency voltage to the opposing electrode (discharge space) are the same as those described above. Among them, the high frequency voltage (applied voltage) and the discharge starting voltage can be measured by the following methods. High-frequency voltage: VI, and V2C unit: kV/mm) The high-frequency probe (P6015A) of each electrode section was placed, and the high-frequency probe was connected to an oscilloscope (TDS3012B, manufactured by Tektronix Co., Ltd.), and the voltage was measured. Measurement method of discharge starting voltage: IV (unit: kV/mm) A discharge gas is supplied between the electrodes to increase the voltage between the electrodes, and the voltage at which the discharge starts is defined as the discharge starting voltage: IV. The detector is the same as the above high frequency voltage measurement. By discharging a higher voltage, for example, even if the discharge voltage such as nitrogen is a higher discharge gas, the stable plasma state can be maintained at a high density when the discharge gas is activated. When the discharge gas is used as the nitrogen gas by the above measurement, the discharge starting voltage: IV is about 3.7 kV/mm. Therefore, in the above relationship, the first high frequency voltage is V123.7 kV/mm, and the nitrogen gas is externally excited. It can be made into a plasma state. Examples of the discharge gas include rare gases such as nitrogen, helium, and argon, air, hydrogen, and oxygen. These may be used as a discharge gas alone or in combination, but when nitrogen is used, helium or argon is used. When the rare gas is compared, it is particularly preferable because the discharge gas can be obtained with high economic efficiency. The high frequency power supply provided in the atmospheric piezoelectric slurry processing apparatus is the same as the above, but the frequency of the first power source (high frequency power source) and the second power source (high frequency power source) can be classified as follows. As the first power source, the following sales items can be used. High frequency power supply company name frequency number A1 Kobelco motor 3kHz A2 Kobelco motor 5kHz A3 spring motor 15kHz A4 Kobelco motor 50kHz A5 Hayden Institute 100kHz* A6 pearl Industrial 200kHz and * symbol for Hayden research institute high frequency power supply (continuous Paint mode l〇〇kHz). Further, as the second power source (high-frequency power source), the following sales-123-200904636 可 can be applied.

It is also preferable to have an electrode temperature control means for controlling the electrode temperature. Further, in the electrodes of Figs. 7 and 8, the metal base material and the dielectric body are shown. However, as in the case of Figs. 9 and 10, the metal base material of the electrode may of course be covered with a dielectric body. The high frequency voltage applied between the opposing electrodes may be an intermittent pulse wave or a continuous wave of information, but a continuous signal wave is preferred. The distance between the electrodes can be determined in consideration of the thickness of the dielectric provided by the metal base material of the electrode, the magnitude of the applied voltage, and the like. The shortest distance between the dielectric body and the electrode when the dielectric is placed on one of the electrodes, and the distance between the dielectric bodies when the dielectric is provided on both of the electrodes are 0.5 to 0.5 mm from the viewpoint of uniform discharge. 20 mm is preferable, preferably 0.5 to 5 mm, more preferably 0.5 to 3 mm', and particularly preferably imm ± 0.5 mm.

An optical compensation film (phase difference film) having a phase difference of ~400 nm is preferred. For example, it can be produced by the method described in, for example, JP-A No. 2 002-7 1 95 7 and JP-A-2003-170492. Further, it is preferable to use a polarizing plate protective film having an optical compensation film having an optical heterogeneous layer formed by aligning a liquid crystal compound such as a discotic liquid crystal. The optical anisotropic layer can be formed, for example, by the method described in JP-A-2003-98348.
