According to the present invention, the optical functional layer can be provided in a shorter period of time than before, and a multilayer film excellent in productivity of an optical film can be produced. Further, according to the present invention, since the adhesion of impurities is prevented, a uniform optical functional layer is formed, and the yield of the oxime is improved, and the productivity is improved. [Embodiment] As shown in Fig. 1, the multilayer film 1A of the first embodiment of the present invention, the support body 11 and the hard coat layer 12 are provided. The support 11 is composed of a polymer compound. The hard coat layer 12 protects one surface (hereinafter, referred to as a first surface) 11a of the support body 11. As shown in Fig. 2, the multilayer film 20 of the second embodiment has a support 11, a hard coat layer 12, and a first adhesive layer 21. The first bonding layer 21 enhances the adhesion between the gamma 11 and the hard coat layer 12, and bonds the support 11 to the hard coat layer 12. The support 11 and the hard coat layer 12 are the same elements as those in Fig. 1, and thus the description thereof is omitted. In the subsequent step, a photofunctional layer is provided as a photophosphorus in the multilayer molds 10, 20. The photofunctional layer is provided on the other side of the support 11 (hereinafter referred to as "201127916 N/〆" νγ 1 2 surface) lib. For example, a form in which the multilayer film 2 is applied to an optical film is shown in Fig. 3. The film 25 is provided with a photo-functional layer 26 on the second surface lib of the support 11 of the multilayer film 20. The photo-functional layer 26 refracts and condenses incident light to form a lens layer or a ruthenium layer. Fig. 3 shows a case where the photofunctional layer 26 is used as a germanium layer. The photofunctional layer 26' as a germanium layer forms a plurality of cross-sectional triangles at a constant pitch. When the light is incident on the side of the coating layer 12, the optical film 25 having the light-functional layer 26 refracts the incident light toward the predetermined direction by the prism, thereby emitting light with a light distribution having a large peak as in a predetermined direction. For example, if the incident light is refracted toward the normal direction, it becomes a light distribution having a large peak as in the normal direction. Thus, if the optical film 25 is used for a backlight unit of a liquid crystal display, the front side of the liquid crystal display is improved. Brightness. Light functional layer 26 As will be described later, the multilayer film 3 of the third embodiment has a support 11, a hard coat layer 12, and a second spot layer 31. The second layer 31 is provided on the support body 11. In the surface lib, that is, the multilayer film 3 is formed by further providing the second adhesive layer 31 on the multilayer film 10. As shown in Fig. 5, the multilayer film 4 of the fourth embodiment has the support 11 The hard coat layer 12, the first adhesive layer 21, and the second adhesive layer 31. That is, the multilayer film 4A is in the form of further providing the second dry layer 31 on the multilayer film 2's. A light functional layer is provided on the multilayer films 30 and 40. The second adhesive layer 31 of the multilayer films 30 and 40 improves the adhesion between the support u and the optical functional layer 26, and bonds the support u to the foregoing. Light functional layer. Example 201127916 36920pif and film 45 through '(4) in the form of silk film, as shown in Figure 6, light; 2 face 2 bonding layer 31 'on the support body 11 of the multilayer film 40 Fig. 3 has a light function layer 26. The light function layer 26 in Fig. 6 is not limited to this. For example, the layer of light power has a structure and a structure. The light correction 26 refracts light as described above to condense light or admin. This controls the light path. In terms of light, there is a case where the surface of the 2 energy layer 26 is The difference between the incident angle and the refractive index of the η and the optical power 匕曰 26 is refracted, or the light emitted by the human person is refracted or reflected on the exit surface. This is used according to the configuration of the optical layer 26. When the optical films 25 and 45 are used in a backlight unit of a liquid crystal display, when the light from the light source is incident from the hard coat layer 12 side, the optical function layer 26 sometimes has a 稜鏡 function and a lens function. The optical films 25, 45 can be used as so-called cymbals, lens sheets. Further, when light from the light source is incident from the side of the hard coat layer 12, the optical function layer 26 may have a diffusion function. • The optical films 25, 45 having such a function can be used as a so-called diffusion sheet.功 Power Month b. The lens function is a function that controls the concentration of incident light to emit light, such as a light distribution having a large peak in a predetermined direction, to adjust the front luminance of the liquid crystal display. Further, the diffusion function is a function of diffusing incident light to have an equal light distribution. When the photo function layer 26 is a lens layer, a plurality of lenses which are arranged at a predetermined pitch to constitute refracted light are formed. When the light emitted from the second surface 1 of the support 11 is incident on the light function layer 26, the light function layer 26 controls the exit angle of the incident light 201127916 -----Γη degree. As the lens, there are a cylindrical lens, a spherical lens, and an aspherical lens which are divided into two in the axial direction, and may be a triangular shape. Therefore, the light functional layer 26 as the enamel layer as shown in FIGS. 3 and 6 can also be referred to as a light-functional layer 26 of the lens layer as the enamel layer or even the lens layer, and has an embossing method. The situation and the formation by the mold polymerization method. A mold polymerization method which is more productive than the embossing method is usually used. In the mold polymerization method, a film made of a UV-curable compound which is cured by ultraviolet rays (uv) is usually formed into a predetermined shape, and the compound is cured by UV while maintaining its shape. As the photofunctional layer 26 is formed by curing, a plurality of predetermined prisms or even lenses are formed. That is, the photofunctional layer 26 is a photocured portion which is cured by light. When the photo-functional layer 26 is formed by a mold polymerization method, a substance having a monomer having a radical polymerizable double bond, an oligomer, or a polymer as a main component is generally used as a material, and a polymerization initiator is further included in the material. Among the main ingredients. Examples of the monomer or oligomer having a radical polymerizable double bond include an acrylic monomer and an acrylic oligomer. From the viewpoint of mass productivity, the embossing method is more preferably a mold polymerization method, and in the mold polymerization method, a mold polymerization method using a UV curable compound is also preferred. As described above, in the subsequent step, the photofunctional layer 26 is formed on the second surface lib side of the peripheral body 11 of the multilayer films 1A, 2B, 30, and 40. Therefore, when light is incident from the hard coat layer 12 side, the multilayer films 1 〇, 2 〇, 3 〇, and 4 〇 are all set such that the light transmittance at a wavelength of 340 nm in the incident light is in the range of 70% or more and 1% or less. As a result, the process after the application of the photofunctional layer 26 can be shortened, the production efficiency of the optical films 25 and 45 can be improved, and the productivity can be improved. 201127916 36920pif Generally, the main luminescence wavelength of a metal crystallization lamp for UV curing is in the range of 340 nm or more and 400 nm or less, and the main emission wavelength of a high pressure mercury lamp is 365 nm. Further, the transmittance of the multilayer film which requires transparency in the visible light region tends to be lower in the range of 34 〇 nm or more and 4 〇〇 nm in the lower range, and the transmittance becomes lower as the wavelength is shorter. Therefore, it is preferable that the light transmittance of at least 340 nm is 70% or more and less than 1% by weight. Particularly preferably, the light transmittance is 7〇% or more and the small φ is 100% over the entire range of 340 to 400 nm. When the light transmittance of the wavelength of 340 nm is less than 70%, when the photofunctional layer 26 is provided on the second surface lib side by uv curing, the uv irradiated from the side of the hard coat layer 12 by the metal halide lamp or the still-pressure mercury lamp is absorbed. To the multilayer film 10, 20, 30, 4〇. Due to this absorption, it is possible to contribute to a decrease in the UV intensity of the curing for forming the optical function layer 26. As a result, the curing efficiency of the photofunctional layer is lowered. When the curing efficiency is lowered, the curing time is required until the predetermined curing state, and the productivity of the optical film is lowered. Further, when the curing time is not lengthened, since the curing of the photofunctional layer 26 is insufficient, the scratch resistance of the optical function layer 26 becomes insufficient. In the case of the multilayer film 10, 20, 30, and 40, when light is incident from the side of the hard coat layer 12, it is more preferable that the light transmittance at a wavelength of 365 nm in the incident light is 76% or more. This is particularly effective when a high pressure water is used as a light source for illuminating light used to form the light energy layer 26. This is because the bright line of the high pressure mercury lamp is 365 nm light. [Support] The support 11 is a film having a high molecular compound by a melt film forming method or a solution film forming method. Polymerization for the support u 11 201127916. The object is transparent. When the light is applied to the multilayer film 10, 20, 30, 40' as the multilayer film 10, 20, 30, 40', and the light is incident on the multilayer film 10, 20, 30, 4, the support 11 further has the following transparency: 70%. The transmittance of 100% or less of the above is transmitted from the second surface lib by transmitting light having a wavelength of 340 nm in the incident light. As the support 11, polyethylene terephthalate (PET), polyethylene naphthalate (PEN), polybutylene terephthalate (PBT), polynaphthalene are preferred. Butylene dicarboxylate (pBN), polyarylate, polyether sulfone, polycarbonate, polyether ketone, polysulfone, polyphenylene sulfide, polyester liquid crystal polymer, triacetyl cellulose, cellulose derivative Materials, polypropylene, polyamides, ruthenium amide, polycyclic hydrocarbons, etc. Among them, PET, PEN, triacetyl cellulose, and cellulose derivatives are more preferably PET or PEN. Further, it is preferable to use a biaxially oriented polymer film as the support 1 and the biaxially stretched polymer film, and the polymer compound has a long film shape and is biaxially stretched in the longitudinal direction and the width direction. . From the viewpoint of elastic modulus and transparency, it is particularly preferable to form a film ρΕτ,

The two-way stretcher acts as a support U. Further, the branch body 11 may be subjected to a corona discharge treatment by at least any of the i-th surface 11a and the second surface lib. The i-th surface and the second surface 11b are hydrophilized by corona discharge treatment. Thereby, the wettability of various aqueous coating liquids described later can be improved. Further, by the corona 4 discharge treatment, a functional group such as a county or a radical can be introduced. By so as to improve the lubricity or the introduction of the g-b b group 'the first surface and the hard coating of the second layer 21, or the second surface dich function layer 2; 12 201127916 36920pif or the second stick The adhesion of the bonding layer 31 is further improved. The heat shrinkage ratio of the support U when the hard coat layer 12 is formed by thermal curing is preferably in the range of 0.1% or more and 3.0% or less, more preferably 〇 2% or more and 25% 〇. The following range ' is particularly preferably in the range of 0.4% or more and 2.0% or less. ^ The above values of the heat shrinkage rate are values at Π〇ΐ, 10 minutes. As will be described later, the 'hard coat layer 12' is formed by applying a predetermined coating liquid for forming the hard coat layer 12 directly or through the second adhesive layer 21' to the support η, and heating it to 16 (rc or more). The temperature is formed by curing by heating. The coating film shrinks by dehydration condensation of decyl alcohol in the coating film at the time of heat curing, and then, by using a support having a shrinkage ratio as described above. 11. The hard coat layer 12 is formed without cracking, and the curl of the support body 11 can be prevented. This is because the branch body 11 is deformed in association with the f at the time of curing of the coating film. That is, because the support body 11 is The shrinkage of the coating film forming the hard coat layer 12 2 is followed. Therefore, the heat shrinkage rate of the support ship u is preferably such that P is the same as or at the temperature close to the film temperature. When it is difficult to produce a substance to be described later as a coating liquid, the heating shrinkage rate is targeted. In order to prevent measurement errors, the holding time in the heating shrinkage ratio of the main support 11 is preferably 10 minutes. The ratio may be longer than 1 minute. But when it is longer than ι〇, the effect is not better than The heating shrinkage ratio of the cut body 11 is set to 0.1% or more, and the coating film is changed in accordance with the curing shrinkage of the coating film as compared with the small shape, and the coating film is made by the difference in shrinkage ratio between the two. In the case where the heat shrinkage ratio is more than 3%, the film 13 201127916 ^oyzupif film crack is not produced. However, the heat shrinkage rate is set to 3% or less, and more than two months. 11 * The degree of deformation of the body is reduced. Therefore, the multilayer films H), 2G, and 3G can be used as the Pingcheng and more reliably. First, the sample is directed to it. The sample was previously measured in a predetermined square and the length was set to u. For the sample of the measured length u, i7〇t constant coffee is placed _. Second,: ° to give the inside to send people hot air and keep the inside as heating dad. After cooling the heat-treated sample, the length was measured in the same direction as the direction in which the mouth was measured. The length is set by the formula: {(1) cut handsome (10) to find the heating shrinkage rate ^ 位 position ' / 〇). However, the present invention is not limited to the above method of heat shrinkage. For example, when the heating shrinkage ratio is obtained by another measurement method, the correlation between the measurement method used by the method and the value obtained by the above method is determined according to the relationship, and the measured value corresponds to the range of the above-described value obtained by the above method. can. The heat shrinkage ratio is preferably in the range of 17 (rc, 10 minutes, 〇. 1% or more and 3% or less, more preferably 〇. 2% or more and 25% or less). In addition, when the first adhesive layer 21 is provided, the heat shrinkage ratio of the support layer 11 having the state of the i-th adhesive layer 21 may be within the above range. Bonding layer or second bonding layer] In order to improve the adhesion of the support 11 to the hard coat layer 12 and to improve the adhesion to the 201127916 36920pif hard coat layer 12, the i-th bonding layer 21 is appropriately placed on the support. On the first surface 11a of the body 11. In order to improve the adhesion of the support u to the optical function layer 26 and to improve the adhesion to the optical function layer 26, the second adhesive layer 31 is appropriately disposed on the support 11. On the second surface 11b, the first and second adhesive layers 21 and 31 are formed by applying a coating liquid composed of a binder, a curing agent, and a surfactant to the second surface 11a and the second surface lib, respectively. For the purpose of adhesion to each of the hard coat layer 12 and the photofunctional layer, it is used on the first and second adhesive layers 21 and 31, respectively. It is preferable to select suitable materials for each of them. Further, it is also possible to appropriately contain organic or inorganic fine particles in the No. 2 contact layer 21, 31. - The adhesive used on the first and second adhesive layers 21, 31 There is no particular limitation. Among them, at least one of a polyester, a polyaminophthalic acid ester, an acrylic resin, and a styrene butadiene copolymer is preferred from the viewpoint of adhesion. It is particularly preferable from the viewpoint of the fact that the water-soluble or water-dispersible person has a small load on the environment. In order to adjust the refractive index of the second adhesive layer 21, 31, the upper and the second dry layer 2 The ruthenium may also be composed of a metal oxide. As the metal oxide, a refractive index such as tin oxide, cerium oxide, zinc oxide, titanium, cerium oxide or cerium oxide is preferred. The high one can change the refractive index even in a small amount. The metal oxide fine particle diameter is preferably in the range of 1 nm or more and 5 〇 nm or less, particularly preferably in the range of 2 legs and 4 〇 nm or less. The amount of the metal oxide particles is woven according to the target. : Ϊ定, preferably, to the first and second layers 2, 31, ', "When the mass is set to 100, the particle mass is in the range of 1〇 to 90 or less. 15 201127916 36920pif The refractive index of the bonded reed 21 12 determines the first Ϊ; 12 f L The refractive index of the transfer layer 21 is set to 0, 0 2, the refractive index is set to nl2, will go to 11 >#&# is W, especially good for the next _ the refractive index of the branch 11 is set to n21 (nl2-nll) coated ^ 形成 to form each layer 2 For each of the dead solutions of the type 31, 'control: the thickness 粘接2 of the adhesive layer 21 and the second adhesive layer' T31.

Can be suppressed to $ plus. The range of better thickness melon and T31 is the following for reading Qing. Further, in the same manner as in the case of the refractive index, in order to reduce the interference color when the light is irradiated from the side of the hard coat layer to the film 10, 20, 30, 40, it is preferable that the interference color becomes unsold. The thickness of the first adhesive layer 21 is determined by the refractive index M2 of the hard coat layer 12 and the refractive index n21 of the first adhesive layer 21, and it is particularly preferable to set the following _. Further, in the following formula t, λ is a measurement wavelength. 201127916 36920pif „ *Good for considering high luminosity of 5 (8) nm or more _ T2f==:!=.

[Hard Coating Layer] The hard coat layer 12' protects the second surface 11a of the support 11 as described above. The hard coat layer 12 is used to compensate for the hardness and scratch resistance of the multilayer film 1〇, 2〇, %, 4〇. When the multilayer film 10, 20, 30, and 40 are used as the multilayer film 10, 20, 30, and 40, the hard coat layer 12 has the following transparency: the above-mentioned transparency is more than 1 GG% or less. The transmittance is transmitted from the second surface ub of the support u by transmitting light having a wavelength of 340 nm in the incident light. More preferably, the hard coat layer 12 has transparency of 72% or more and 100% or less of transmittance "transmitting light having a wavelength of 340 nm in incident light, and is emitted from the second surface lib of the support 11. When the light is incident on the respective multilayer films 10, 20, 30, 40 as the multilayer films 10, 20, 30, 40 together with the support 11, the hard coat layer 12 is more preferable, and has the following transparency: 76% The above transmittance of 1% or less is transmitted through the second surface lib of the support 11 by transmitting light having a wavelength of 365 nm in the incident light. The thickness T12 of the hard coat layer 12 is not particularly limited. Among them, from the viewpoint of transparency and strength of good 17 201127916, the thickness T12 is preferably in the range of 〇 5 μπι or more and ΙΟμηη or less, more preferably in the range of 〇8 μm or more and 8 μmη or less, and particularly preferably in the range of Ι.ίμιη to 6 μιη. The coating amount of the hard coating layer 12 to be described later to form the hard coat layer 12 can be adjusted. However, when the impurities adhere to the surfaces of the multilayer films 10, 20, 30, and 40, when the @光光魏层26 is formed, the miscellaneous (four) hinders the transmission of UV light as the illuminating light. Due to the transmission of uv light, sometimes the photofunctional layer 26 is partially incapable of solidifying and becomes a defect. At this time, the optical film has a reduced rate of illusion, or the time for curing it to become a uniform light functional layer 26 becomes longer. As described above, when impurities are attached to the multilayer film 1 〇, 2 〇, 3 〇, the productivity of the optical film 25 45 is remarkably lowered. Therefore, the hard coat layer u is. 〇, 40% RH surface power is better, grab / (10) upper Μ%, □ below. ^ 光学 The optical films 25, 45 are given electrostatic functions. In addition, the Ω/port also has a surface resistivity of ι〇12ω/port or less, and in the process of providing the optical function layer%, the multilayer film 10, 2° is compared with the case of more than 10 Ω/□. , 3. , 4. The surface. As a result, the yield of the film is increased. Therefore, when the productivity of the optical films 25 and 45 is adhered to the optical films 25 and 45, the quality of the backlight is not deteriorated. For example, the display contrast of the display deteriorates. In addition, when there is a lens sheet in the first unit, the optical film 25 manufactured by using the multilayer film Η), 2G, 30, and 4G is attached to the lens of the Osaki = = 201127916 36920pif. , the surface of 45. Therefore, when the surface resistivity of the hard coat layer 12 is set to 1 〇 17 / or less, the problem of the display quality as described above is less likely to occur than in the case of more than 1 () 12 Ω / 。. Further, in terms of setting the surface resistivity of the hard coat layer 12 to less than 108 Ω/□, there is no problem in the performance of the multilayer film 10, 2〇, 30, 4〇 and the optical films 25 and 45, but there is manufacturing. The cost becomes higher: The cost of the class is high. In order to provide an antistatic function to the multilayer film 1 〇, 2 〇, 30, 40, it is preferred to add a cation, a cation, a coating liquid to form a hard coat layer by a method of forming the hard coat layer 12 having the above surface resistivity. Beet ionic electric agent two towels, preferably 2_minus_Ν_country ethyl green ethyl miso beet beet test and other sugar beet with seven-turn skeleton (four) compound 1 ion steep antistatic agent or otherwise It is also possible to use a metal oxide structure such as conductive tin oxide, zinc oxide, cerium oxide, magnesium oxide, or oxidized recording to impart antistatic function to the multilayer films 1G, 2G, 3G, and 4G. 12 contains a conductive material, and may contain a conductive material in any of the first drill-contact conductive contact layers 31. The electric material 'is preferably a metal oxide such as oxygen (10), indium oxide or oxygen argon, or a polycondensation, a material phen, a polystyrene or a first molecule. These materials are added to the coating liquid for forming the first dry layer 21 "r contact layer 31, and this can be applied to the multilayer film "冬仙职" to prevent the electrostatic body (1). Other optical components such as light plate and thinning 201127916 When one stack is used in combination, there is a possibility that the optical films 25 and 45 are scratched or rubbed against each other by contact or friction with other optical components. For the purpose of avoiding this possibility, it is also possible to provide moderate unevenness on the surface of the hard coat layer 12. As a means for providing irregularities on the surface of the hard coat layer 12, a light-removing material is added to the coating liquid for hard coating which becomes the hard coat layer 12, which is easy to manufacture. As the light-removing material, various organic or inorganic fine particles can be used, and are preferably cerium particles, polystyrene particles, polystyrene-divinylbenzene copolymer particles, cerium oxide particles or the like. The particle size of the light-removing material is preferably in the range of 〇.3 μm or more and 5 μmη or less. If the particle size of the light-removing material is 〇 3μηι#, the light-removing material is less likely to be buried inside the hard coat layer 12 than in the case of less than 0.3 μm, and it is easier to surely obtain the surface unevenness. Further, when the particle size of the light-removing material is 5 μm or less, the height of the convex portion protruding from the surface of the hard coat layer 12 does not become excessively larger than in the case of more than 5 μm. Therefore, it is possible to more reliably avoid the problem of scratching other optical components, or removing the light-removing material from the hard coating layer π. The particle size of the light-removing material is more preferably in the range of 06 μηη or more and 3 μm or less. The amount of the light-removing material to be added is not particularly limited as long as the target surface unevenness can be obtained. However, from the viewpoint of optical characteristics, it is preferred that the haze ratio of the multilayer film 10, 20, 30, 40 is not more than 30%. The amount is particularly preferably not more than 20%. The hard coat layer 12 is preferably formed of a liquid coating composition as a component of the coating liquid for hard coating, and is not particularly limited as long as it is cured by at least one of heat and active energy rays. Among them, in order to satisfy the above-described transmittance of the predetermined wavelength light of the multilayer films 10, 20, 30, and 40, it is preferable to form the hard coat layer 12 having a high light transmittance of 340 nm or more and 400 nm or less. 201127916 36920pif In addition, a coating agent for hard coating may be formed by adding a polymerization initiator, a curing agent, or the like as needed. In the above, the coating liquid for hard coating is also preferably a thermosetting coating liquid which does not require a photopolymerization agent. That is, it is preferred to apply a coating liquid to be thermally cured, and to cure the coating liquid for hard coating by heating to form the hard coating layer 12.

Examples of the material to be thermally cured include a general thermosetting resin such as a urethane resin, an epoxy resin, a phenol resin, a melamine resin, a urea resin, an amino resin, and an anthrone material. In particular, an anthrone resin having a three-dimensionally crosslinked nonanexane bond can form a high-hardness film because of high crosslinking density. Further, by using a thermal polymerization initiator in combination, a monomer or oligomerization having an acrylic group or a mercaptoacryl group containing a double bond capable of free radical polymerization can be used. As the monomer, dipentaerythritol hexa(indenyl) acrylate vinegar, di-mercaptopropane tri(meth) acrylate, trishydroxypropyl propane polyethoxy tris(decyl) acrylate, and three are preferable. A polyfunctional monomer such as hydroxymethylpropane polypropoxy tri(meth) acrylate, pentaerythritol tetrakis(meth) acrylate, or bistrimethylolpropane tetracarboxylic acid S. Further, an oligomer such as an amino phthalate acrylate having an acrylic acid group or a mercapto acryl group, an epoxy acrylate, a polyester acrylate or a polyether acrylate is also preferable. Further, preferred are styrene, divinylbenzene, phenylpropene, diphenyl propylene, triallyl isocyanurate, dipropylene phthalate, diethylene glycol bis(allyl carbonate). Wait. In order to set the hard coat layer 12 to the desired physical properties, it is preferred to use a plurality of these monomers and oligomers in combination. 21 201127916. < ^^ Initiator> As the polymerization initiator, for example, a thermal polymerization initiator which is usually used for polymerization of a monomer or an oligomer having a double bond capable of radical polymerization can be used. As an example of a thermal polymerization initiator, an organic oxide, an azo compound, or the like can be used.

The amount of the polymerization initiator to be added is preferably in the range of 0.1 to 10% by mass based on the coating liquid for hard coating. In the case where the absorption wavelength is in the range of 34 Å or more and 4 Å or less, the amount of use is limited so as to prevent the transmittance of the wavelength light caused by the hard coat layer 12 from being lowered as much as possible. Further, by using a photopolymerization initiator as a polymerization initiator in combination, a monomer or oligomer having an acrylic group or a mercaptoacryl group containing an exemplary radically polymerizable double bond can be used as described in the thermal polymerization. However, the photopolymerization 22 201127916 36920pif initiator has a absorption wavelength of 340 nm or more and 4 Å or less. Therefore, when a photopolymerization initiator is used, the amount of use thereof is suppressed to a minimum.

Specific examples of the photopolymerization hair styling agent include acetophenone, diphenyl guanidine, benzoin oxime ether, benzoin ethyl ether, benzoin butyl sulfonium, acetophenone ketone, acylphosphine oxide, and 2 - ethyl hydrazine, biformyl decyl alcohol, acyl phosphine oxide, and further, a toothed hydrocarbon having a triazine skeleton, a toothed hydrocarbon having an oxadiazole skeleton, a phenyl acridine derivative, A ketone compound, a ketone oxime compound, an organic peroxide, a sulfur compound, and a hexaaryldiamine.

The organic hydrazine compound represented by the formula (1) does not contain an amino group as a functional group. That is, the organic ruthenium compound has an amino group-containing organic group Ri. When R1 has an amino group, when it is mixed with a tetraalkoxy decane and hydrolyzed, the produced sterols promote dehydration condensation, and therefore, the coating liquid for hard coating becomes unstable. R1 may be an organic group having a molecular chain length such as a carbon number in the range of 15 or more and 15 or less. Among them, in order to obtain the hard coat layer 12 in which the brittleness is further improved, and in order to further improve the adhesion between the hard coat layer 12 and the support 11 or the first adhesive layer 21, the carbon number range is more preferably 3 or more and 15 or less. It is preferably 5 or more and 13 or less. Further, by setting the carbon number to 15 or less, the softness of the hard coat layer 25 201127916 12 is not excessively large to form a sufficient hardness as compared with the case of 16 or more. Further, the organic group represented by R1 is preferably a hetero atom having oxygen, nitrogen, sulfur or the like. By having a heterocyclic atom in the organic group, the adhesion to the support 11 or the first bonding layer 21 can be further enhanced. Particularly, it is preferred to have an epoxy group, an amine group, an aminodecanoate group, a urea group, an ester group, a hydroxyl group, a carboxyl group or the like in the organic group R1. Among them, an organic ruthenium compound containing an epoxy group is particularly preferable because it has an effect of improving the stability of sterol in acidic water. &lt;Tetraalkoxydecane&gt; The second component of the coating liquid for the first hard coating is chopped by using a four-alkoxy group, and the tetradecyloxydecane and the organic anthracene compound of the formula (1) are extracted. The crosslink density of the dehydration condensation of decyl alcohol produced in the hydrolysis. Thereby, the hard coat layer 12 harder than the prior art can be formed. The tetraalkoxydecane is not particularly limited. More preferably, the number of carbon atoms is 1 to 4, and particularly preferably tetradecyloxysulfonium or tetraethoxysulfonium. When the carbon number is 4 or less, the hydrolysis rate of the tetra-oxygen oxyselicin with the acidic hydrazine is not too slow compared with the case of 5 or more, and the time required for dissolution into a uniform aqueous solution becomes more. short. The mass of the organic hydrazine compound of the formula (1) is XI, and the mass of the tetra-oxygen decane is X2. The mass ratio of the tetra-Oxide-based sinter calcined by {X2/(X1+X2) }xl〇〇 is preferably in the range of 20% or more and 95% or less, particularly preferably in the range of 30% or more and 90% or less. By setting the mass ratio of the range, the crosslinking density can be increased, so that the hard coat layer 12 having a sufficiently high hardness and further improving the brittleness can be obtained. When the mass ratio is 20% or more, the crosslinking density is not too low as compared with the case of less than 20%, so that the hard coat layer 26 201127916 36920pif 12 does not become hard. Further, when the mass ratio is 95% or less, the crosslinking density does not become excessively higher than when it exceeds 95%. Therefore, the hard coat layer 12 having good flexibility and no brittleness can be obtained more surely. &lt;Acid water&gt; The acidic water as the third component of the coating liquid is preferably in the range of 6 or less in the hydrogen ion index jpH) or more, and particularly preferably in the range of 2 5 or more and 5 5 or less.疋 because 'when the pH is less than 2 or greater than 6, there is a tendency to: _ * mix the tetra-alkoxy and the organic hybrid of the formula (1) in the acidic water = as an aqueous solution, the oxy-oxygen is burned in the aqueous solution In the middle, that is, after hydrolyzing in the aqueous solution of the alkoxylate, the formation of the linalool, the condensation of the linalool is changed, and the degree of dryness of the aqueous solution is increased. Further, the above positive value is a value under the so-called "room temperature" of 25t:. Acidic water is obtained by dissolving organic acid or inorganic acid in water. There is no specific limitation. Acetic acid, propionic acid, acid, fumaric acid, maleic acid, oxalic acid, malonic acid, succinic acid, citric acid can be used. , malic acid, ascorbic acid and other organic acids, hydrochloric acid, nitric acid, sulfuric acid, dish acid, acid and other inorganic acids.苴 • From the viewpoint of handling, acetic acid is preferred. The octadecyloxy Wei aqueous solution is prepared by combining the amount of the tetra-oxygen oxy-stone and the luminescent compound of the formula (1), that is, when the amount of the methoxy group used is 100 parts by mass, the amount of acidic water is 6 〇. Fine parts or more fine: S: the following range. By setting it as such a composition, it is possible to obtain a hydrolyzed aqueous solution of a oxidic mechanical agent having good hydrolyzability and a turbidity of the resulting material. In addition, the first aqueous solution for hard coating which is obtained by using an aqueous solution, which is obtained by using an aqueous solution, is stable, and is excellent in stability without being limited to water. Therefore, the limitation of the _ hiding time before the start of manufacturing the multilayer film 10, 20, 30, 40 is small, and the multilayer film 10, 20, 30, 40 连续 « Λ- 连续 is also continuously produced without the coating liquid for hard coating. In the case of the amount of acidic water, 100 parts by mass of the tetraalkoxydecane and the organic compound of the formula (1) are more preferably 100 parts by mass or more. It is particularly preferably in the range of 150 parts by mass or more and 1200 parts by weight or less. When the amount of the acidic water is less than 60 parts by mass based on 1 part by mass of the alkoxy decane, there is a tendency that the dehydration condensation of the alkoxy decane is carried out by hydrolysis of the alkoxy decane, thereby facilitating gelation of the aqueous solution, ^ By attacking 6Q parts by mass or more, the gel can be more reliably suppressed. On the other hand, when the acidic water is 2000 parts by mass or less, compared with the case where it exceeds 2000 parts, the coating liquid is oxidized by Wei. The concentration is high, and the coating amount for forming the hard coat layer 12 to a sufficient thickness does not become =: Therefore, it is possible to more reliably prevent the uneven thickness of the coating film for hard coating or the long-term drying time of the coating film. Chemical. The compound is used in a coating liquid for hard coating with a tetrazide-based Wei and a compound of the organic stone of the formula (1). In this case, it is preferable to buy a weight of &lt;colloidal cerium oxide&gt; in a range of less than 2 parts by mass relative to the total amount of the four alkoxy decane and the other Wei compound, 1οϋ, 1).

The average particle size of the colloidal particles is 3 or more, the first! The hard coating does not become too high, so the addition of the (10) state of the dioxin can also form the hard coat layer 12 more hardly. Further, by the average particle diameter of the particles being 5 Q nm or less, a person is irradiated to the hard coat layer. The light scattering does not become excessively large, so that the transparency of the multilayer films 1g, 2g, 3〇 f optical films 25, 45 is not impaired. The average particle diameter of the colloidal particles is preferably in the range of 50 nm or less, more preferably 4 Å or less in the pulmonary ridge, and particularly preferably in the range of 5 nm or more and 35 nm or less. The outer-colloidal dioxide dioxide dream is more preferably adjusted as follows: the pH (hydrogen ion index) at the time of addition to the coating liquid for application is 2 or more in the range of:. When the pH is 2 or more and 7 or less, the hydrolyzate of the alkoxydecane, that is, the stability of the decyl alcohol, is more stable than the case of less than 2 or more, and the dehydration condensation reaction odor by the frequency can be more surely suppressed. The viscosity of the coating liquid caused by the continuous progress increases. 100 parts by mass of the colloidal dioxygen oxide amount relative to the organic cerium compound of the tonoxy group and the formula, preferably 4 〇 mass = 2 GG parts by mass or less 'better (10) The amount of f is more than 15 knives. When the amount of colloidal dioxotomy is 4 parts by mass or less, the volume shrinkage ratio due to dehydration condensation at the time of η heat curing increases, and cracks may occur in the film, but the amount is 4 G f. The above can further suppress the crack. Further, when the amount of addition of the colloidal dioxin exceeds the mass fraction, the film brittleness becomes large, and the multilayer film is bent, 1 〇, 2 〇, 3 〇, 4 〇, and cracked. However, by setting the amount of addition of the colloidal dioxotomy to 200 or less, it is possible to more reliably prevent such a phenomenon. 29 201127916 ^ovzupif <Curing Agent> The curing agent for the fifth component of the first hard coating coating liquid is preferably water-soluble.

The monomers and oligomers are dissolved in water at the molecule +. Further, the monomer and the oligomer are dispersed or dissolved as a polyfunctional ester of the acrylic acid group, and the di-pentaerythritol hexaacrylic acid is self-existing. It is intended to be used as a kind of methacrylate-propylene and propylene propylene solution. The solubility of water is low. Therefore, it is better to use a surface to make a single filature.
