三乙酸酯、苯乙烯、碳酸酯、曱基戊烯、颯、醚、乙酮、 醯亞胺、氟、尼龍、丙烯酸酯、脂肪酯、烯烴等所組成之 5 組群中之一個亞單元之聚合物或共聚物。 較佳為具有選自於酯類諸如聚對苯二曱酸伸乙酯、乙 酸酯類例如三乙醯基纖維素及丙烯酸酯類例如聚曱基丙烯 酸甲酯等中之一個亞單元之聚合物或共聚物。原因在於就 所形成之薄膜之透明度、強度及均勻厚度等性質良好。特 10 別,就透明度、濁度值及機械性質而言,較佳為由具有一 個自旨亞單位之聚合物所組成之基材薄膜100。 此種聚酯樹脂之實例包括聚對苯二甲酸伸乙酯、聚伸 乙基-2,6-萘二甲酸酯、聚對苯二曱酸伸丁酯、聚伸乙基-α, yS-貳(2-氯苯氧基)乙烷-4,4’-二羧酸酯等。於此等共聚酯中 15 可共聚合20莫耳%或更小量之二羧酸組分或二醇組分。於 聚酯樹脂實例中,通常考慮品質、經濟效益等,以聚對苯

200923406 化等)。此外’為了協助黏著,於被覆基材薄膜表面作為广 層後可形成高折射率層110 (例如使用聚胺基曱酸I旨、$ 酯、聚酯丙烯酸酯、聚胺基甲酸酯丙烯酸酯、聚環氣式 烯酸酯、鈦酸酯化合物等被覆)。特定言之,就改良黏著性 良好对用性諸如耐熱性、防濕性等方面而言,基材薄 寸之 醏樹 較佳實例係經由施用一種組成物作為底劑而製造,該組成 物包含經由將丙烯酸系化合物接枝至具有親水基之聚

Field of the Invention This invention relates to a stacked film for optics, and more particularly to a stacked film for optical use which has good antireflection performance and corrosion resistance and can be manufactured cost effectively. BACKGROUND OF THE INVENTION In the PDP, CRT, and LCD displays, light reflected on the screen 10 makes it difficult to view the displayed image. In particular, as the size of the flat panel display becomes larger, solving the aforementioned problems becomes an important issue. In order to solve the aforementioned problems, anti-reflection treatment or glare reduction treatment has been employed, for example, an anti-reflection film is used for the display. The method for preparing such an anti-reflection film is formed by applying a low refractive index material (MgF2) to a substrate film by a conventional dry coating method such as deposition, sputtering, or the like to form a film or a further high refractive index via stacking. Materials (ribs: tin-tin oxide steel, fine: tin-doped oxide, Zn, y, etc.) and low-refractive-index materials (MgF2, Si〇2, etc.) are manufactured. However, the antireflection film produced by the dry coating method is not cost effective in commercial production. 2〇 This attempt to solve the aforementioned problem by using an anti-reflection film by a wet coating method, which is actually used for mass production. However, the antireflection film using the wet coating method has a problem that the antireflection film produced by the dry coating method is disadvantageously low in corrosion resistance. 200923406 t SUMMARY OF THE INVENTION: j SUMMARY OF THE INVENTION The present invention is intended to solve the aforementioned prior art problems. SUMMARY OF THE INVENTION An object of the present invention is to provide a stacked film for optical use which can effectively eliminate light reflection on the surface of an image display element, is highly corrosion-resistant, and requires low manufacturing cost.

BRIEF DESCRIPTION OF THE DRAWINGS The features and advantages of the present invention will become more apparent from the detailed description of the preferred embodiments illustrated in the accompanying drawings in which: FIG. 1 shows the principle of the anti-reflection film; A cross-sectional view of a stacked structure of a stack for optics according to the present invention. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, further details of the present invention will be described with reference to the embodiments and the accompanying drawings. It is obvious that the examples are intended to illustrate the details of the invention, but are not intended to limit the scope of the invention. The inventors have studied a method for producing an anti-reflection film which has good anti-reflection performance and anti-sexuality and can be manufactured at a right cost, and thus found that it is suitable for use in a stacking method for optical use. The film is wet-coated*, the method comprises stacking a metal oxide and a refractive index layer containing one compound on the substrate, and then stacking a low refractive index hard coating layer having a given phase, thereby completing the present invention . Further, the method of stacking the wire twisting system of the present invention utilizes a wet breaking method by stacking (4) a high refractive index layer (hereinafter referred to as a "conducting layer") on at least one side of a substrate film, and Then (B) a stack-low refractive index f-side cladding layer is formed. The stacked film for optics according to the present invention can be applied to an image display device by adhering the film to the image display side or its front panel. Preferably, the stacked thin and medium 4 substrate film having good anti-reflection performance according to the present invention has a high light transmittance and a low haze value, and the substrate film is used as a member of the display device. (also referred to herein as "display member"). For example, the light transmission in the wavelength range from nanometer to nanometer is preferably at least 40% and more preferably at least 6G%. The haze value is preferably not higher than 5%' and more preferably not higher than 3%. If one of the aforementioned conditions is not satisfied or the film is used for the display member, the displayed image may not be sharp. In terms of the range of repeatable reproduction, the upper limit of the light transmittance is about 99.5%, and the lower limit of the turbidity value is about 11% to achieve the desired effect. The base film 100 is not limited to a specific type, and may be appropriately selected from the resin materials commonly used in the known plastic substrate film of 200923406. Examples of the resin material for the base film 10 include a material selected from the group consisting of esters, ethylene, propylene, diacetate, triacetate, styrene, carbonate, decylpentene, anthracene, ether, and ethyl ketone. a polymer or copolymer of one of the five subgroups consisting of quinone imine, fluorine, nylon, acrylate, fatty ester, olefin, and the like. It is preferably a polymer having one subunit selected from the group consisting of esters such as ethyl terephthalate, acetates such as triethylsulfonyl cellulose, and acrylates such as polymethyl methacrylate. Or a copolymer. The reason is that the properties of the formed film are good in transparency, strength and uniform thickness. Specifically, in terms of transparency, turbidity value and mechanical properties, it is preferably a substrate film 100 composed of a polymer having one subunit. Examples of such a polyester resin include polyethylene terephthalate, polyethylene-2,6-naphthalate, polybutylene terephthalate, polyethylidene-α, yS - Anthracene (2-chlorophenoxy)ethane-4,4'-dicarboxylate or the like. The copolyester 15 may copolymerize a dicarboxylic acid component or a diol component in an amount of 20 mol% or less. In the case of the polyester resin, quality, economic efficiency, and the like are generally considered, and polyethylene terephthalate ethyl ester is particularly preferred. Any of these resins or a combination of two or more of the classes may be used. The thickness of the base film 20 100 in the stacked film for optics according to the present invention is not limited to a specific value, but is usually from 5 μm to 800 μm and more preferably from 10 μm to 250 μm. The substrate film 100 may be a film formed by joining two or more films in a known manner. Further, before the formation of the high refractive index layer 110, the substrate film 100 may be subjected to surface treatment (e.g., corona discharge, glow discharge, flame treatment, etching or roughing, etc.). In addition, in order to assist adhesion, a high refractive index layer 110 can be formed on the surface of the coated substrate film as a wide layer (for example, using a polyamine phthalic acid, an ester, a polyester acrylate, a polyurethane acrylate) , polycycloolefin acid ester, titanate compound, etc.). In particular, in terms of improving adhesion, such as heat resistance, moisture resistance, and the like, a preferred example of a eucalyptus substrate is produced by applying a composition as a primer, and the composition comprises A copolymer prepared by grafting an acrylic compound to a polyester having a hydrophilic group and a cross-linking binder. Next, a high refractive index layer 110 for a stacked film for optics according to the present invention is formed on a substrate sheet 100. The high refractive index layer 11 〇 mainly contains a conductive particle and a binder component. In the present invention, the conductive particles are metal particles or metal oxide particles. However, in terms of high transparency, metal oxide particles are preferred. Particularly preferred for the metal oxide particles are tin-doped oxide (ΑΤΟ) particles, zinc-doped cerium oxide particles, tin-doped indium oxide (IT〇) particles, oxygen 15 zinc oxide/oxidized granules, and cerium oxide particles. More preferably, it is tin-doped oxide (ΑΤΟ) particles and tin-doped indium oxide (ιτο) particles. Preferably, the conductive particles of the present invention have an average primary particle diameter of 〇 5 μm (the sphere equivalent diameter measured according to the BET rule), but more particularly from 0.001 μm to 0 2 μm. If the average primary particle diameter is higher than the range, 20 the transparency of the produced film (conductive layer 120) is lowered. If the average straight warp system is below this range, the particles may agglomerate, thereby causing an increase in the haze value of the formed film (high refractive index layer 110). Therefore, in both cases, it is difficult to achieve the desired turbidity value. The binder component in the inward refractive index layer 110 is (meth)acrylated 200923406. The (fluorenyl) acrylate compound is subjected to radical polymerization by irradiation with actinic rays, and it is preferred that the solvent resistance or hardness of the produced film can be improved. A polyfunctional (fluorenyl) acrylate compound having two or more (meth) acrylonitrile groups in the molecule is particularly preferable because the solvent resistance is improved. Examples of the polyfunctional (meth) acrylate compound include 3-polyfunctional (meth) acrylates such as pentaerythritol tri(meth) acrylate, trimethylolpropane tri(meth) acrylate, glycerol triterpene (曱) Acrylate, modified ethyltrihydroxymercaptopropane tri(meth)acrylate, bis(2-hydroxyethyl)-isocyanurate tri(meth)acrylate and 4- or more - Polyfunctional (fluorenyl) acrylates such as pentaerythritol tetra(meth)acrylate, dipentaerythritol penta(meth)acrylate, dipentaerythritol hexa(meth)acrylate, and the like. The low refractive index hard coating layer 120 for a film for optical use according to the present invention is formed on the high refractive index layer 110, and mainly contains a (meth) acrylate compound. The (meth) acrylate compound is subjected to radical polymerization by irradiation with actinic rays to improve the solvent resistance or hardness of the produced film. In particular, examples of the (meth) acrylate compound include monofunctional acrylate compounds such as decyl (meth) acrylate, n-butyl (meth) acrylate, polyester (meth) acrylate, (methyl) Lauryl acrylate, hydroxyethyl (meth) acrylate, hydroxypropyl (meth) acrylate. Further, since the solvent resistance of the thin film produced by Machi is improved, it is particularly preferable to use a polyfunctional (meth) acrylate compound having two or more (meth) acrylonitrile groups in the molecule. Specific examples of the polyfunctional (meth) acrylate compound include pentaerythritol tri(meth)acrylate, pentaerythritol tetra(meth)acrylate, dipentaerythritol tris(meth)acrylate, pentaerythritol tetra(meth)acrylate , pentaerythritol penta (meth) acrylate, hexa-11 200923406 (methane) propylene from the pentaerythritol ester, tris (meth) acrylate trimethylol propyl ester and the like. The monomers may be used separately or in combination with two or more types thereof. In the present invention, the configuration for forming the low refractive index hard coating layer 120 is in the form of a stalk, and the knives comprise inorganic particles such as alkyl sulfite and hydrolyzate thereof, j-oxygen cut, dry sulphur dioxide The wet silica sand and the titanium oxide or the silica dioxide particles are dispersed in the colloid or the like to improve the hardness of the hard coating layer. In the stacked film for optical use of this (4), the low-refractive-index hard coating layer contains the Qianyuan polymer. Each of the 10 layers of the layer of the oxygen-containing polymer comprises an inorganic sulfur dioxide compound (also containing a polysilicate), a polyorgano compound, or a mixture thereof. The formation of the layers of the dioxide dioxide or polyorganosiloxane compound can be made in a known manner. Depending on the application, the thickness of the low-refractive-index hard coating layer 12 can be suitably selected, but the car is preferably from 0.05 μm to 10.0 μm. If the thickness of the low refractive index hard coating layer 20 is greater than 1 Å, the transparency of the film produced is lowered, thus resulting in a higher haze value and a more fragile cured film. Under such circumstances, when the film is bent and folded, the defect of the low refractive index hard coating layer 12 is likely to cause cracks. The low refractive index hard tantalum coating layer 120 for a stacked film for optics according to the present invention is formed on the high refractive index layer 110, and mainly contains a fluorine-containing compound. The ruthenium fluoride compound used in the present invention is preferably crosslinked by heat crosslinking or free light crosslinking. The crosslinked fluorine-containing compound may be a fluorine-containing monomer having an unsaturated group or a fluorine-containing polymer having a crosslinking group, or a fluorine-containing monomer subunit and 12 200923406 to produce a crosslinking-based monomer. Copolymer. Particularly preferred is a fluorine-containing copolymer having a structure of ethylene s. Preferably, the fluorinated copolymer has a fluorine content of at least 30% by weight, and the amount of the fluorinated olefin is at least 5 Å and preferably at least 5 〇〇〇 5 average molecular weight in terms of polystyrene. Such a fluorine-containing copolymer is obtained by polymerizing a hardenable composition containing one of a fluorine-containing compound and a vinyl ester compound. Preferably, the obtained form is obtained by polymerizing a hardenable composition comprising a fluorine-containing olefin compound, a vinyl ester compound polymerizable with the fluorine-containing olefin compound, and a desired reactive emulsifier. The hardenable composition preferably used to form the gas-containing copolymer K) comprises a reactive emulsifier as a component. The use of the reactive emulsifier component allows for good application of the fluoropolymer with superior coating and leveling effectiveness. Preferably, the reactive emulsifier is in particular a (iv) reactive emulsifier. The proportion of the structural unit derived from the fluorine-containing olefin compound containing fluorine in the fluorine-containing copolymer 15 contained in the low refractive index hard coating layer 120 is 20 mol% to 7 mol%, preferably 25 Molar% to 65% by mole and more preferably % by mole to 60% by mole. If the ratio of the structural unit derived from the (tetra)hydrocarbon-containing compound is less than 2 mol%, the amount of fluorine in the obtained gas-containing copolymer may be too low, and thus the refractive index of the obtained low refractive index hard coating layer 120 is obtained. The rate failed as follows: 20 Expectations are low enough. At the same time, if the single-tethered horse is derived from the gas-containing dilute compound, the hard coating layer is not good, because the homogenization of the coating liquid is inferior, so it is difficult (four) to reduce The film, and the transparency of the hard coating layer 120 is lowered, and cannot be adhered to the substrate shell as desired. In the far-inclusive murine copolymer, the proportion of the structural unit derived from the compound 13 200923406 component having an ethyl acetate composition is from 10 mol% to 7 mol%, preferably from 15 mol% to 65 wt%. More preferably, the amount of the structural unit of the compound having a vinyl ether structure is less than 1% by mole, and the homogeneity of the coating liquid is inferior, so that it is difficult to form a homogeneous coated film. . 5 10 15 20 If the ratio is higher than 7 〇 mol %, the hard coating 12 g of the ship-bending material is not preferable because optical properties such as transparency are lowered and a low refractive index is obtained. The use of a compound having a reactive official such as a record or a county-based monomer having a compound of ethylene (tetra) is divided into a touch, which is a hardenable tree of the hardened tree, and the product can be cured by a coating material. The strength is improved. The ratio of the monomer to the total amount of monomers having a trans group or an epoxy group is from G to 20 mol%, which is a molar amount. /〇 to 2〇% by mole and more preferably 3% by mole to 15% by mole. If the ratio is in the % of moles, the resulting low refractive index hard coating layer (10) has an optical property = inferior and may cause the film to be weak after hardening. In the fluorinated copolymer comprising a reactive emulsifier, the proportion of subunits derived from the reactive emulsifier component is usually fine moiré such as ◦ mol % and preferably 0.1 mol % to 5 mol % . If / ratio: at 1 G mol%, the resulting low refractive index hard coating layer 12 may be viscous', which is not preferable because the moisture resistance of the treatment is lowered. Preferably, the low refractive index hard coating layer (3) of the present invention contains the compound of (4) in addition to the sharp copolymer because it specifically exhibits a given degree of hardening energy and can effectively improve the hardening efficiency. Examples of the crosslinking compound include an amine compound, pentaerythritol, various ages, a ruthenium salt, and a silk-containing compound such as a hydrolysis product thereof. The amine compound as a crosslinking compound is a compound having an amine group such as a trans group 14 200923406 5 10 15 20 succinyl group or an alkoxyalkyl group and reacting with a group or an epoxy group containing a compound I The compound has two or more groups and is derived from either or both of the other amine groups. Specific examples of the amine compound include a melamine compound 'urea compound, a benzoguanamine compound, and a glycoluril compound. The melamine compound is a compound known to have a framework in which a nitrogen atom is bonded to a triple ring, such as melamine, alkyl melamine, hydroxydecyl melamine, alkoxymercapto melamine or the like. Among them, a compound in which two or more groups are shared by one molecule is preferable, and the group may be either or both of a methylol group and an alkoxymethyl group. Particularly preferred is a supermethylamine, alkoxymercapto melamine or a derivative thereof obtained by reacting melamine with formic acid under an assay condition. In particular, alkoxymethylmelamine is preferred in that it can be cured to obtain a good preservation stability and a good reaction. There are no special restrictions on methyl melamine and alkoxymethyl melamine used as cross-linking compounds, and can be used in the document "Plastic materials with melamine 黯" (Nicole _) High School Press Press) A variety of resins obtained in the manner described. Examples of urea compounds are methylurea-mediated silk-based methylurea, having poly(tetra)-based urine, merging from it, and having a urea group in addition to urine. As for the urinary derivative compound, a plurality of resins described in the foregoing documents can be used. Using #A heavy to 3 fluorocopolymer as the benchmark 'The amount of such cross-linking compound is not more than 7 parts by weight 卟 5 to 30 彳 8 会 μ μ ^ compared with alumina 3 to 50 parts by weight and more difficult If you get the «« ratio, the dosage is higher than 70 parts by weight. If the gelation occurs, the copolymer reacts and the hardened phase does not have a low refractive index, so that the resulting cured film is not as strong as expected. Further, it is preferable that the low refractive index hard coating layer 120 contains a cerium oxide particle coupling agent, and/or a fluorine-containing resin having an oxygen-seeking residue = body anti-residue. The 5 10 15 20 and gasification (four) particles preferably comprise dry dioxo, I oxygen, and bismuth particles dispersed in the colloid. The average of the cerium oxide particles - secondary = straight (bad body equivalent diameter: BET rule) is usually G to micron to 02 micro 隹 嶋 micron to G. 15 micron. If the average particle diameter is within the crucible, the transparency of the low-fold_hard# coating layer 12() is not lowered and the hardness is easily improved. Further, the shape of the diced particles is preferably ^ V or a hollow cylindrical shape. As the (4) particles, two or more components each having particles having a non-particle diameter can be used. Dioxo pellets: surface treatment. For surface treatment, physical surface treatment such as / electric or corona discharge, or chemical surface treatment with a coupling agent may be used for chemical treatment. As for chemical treatment, it is preferred to use a time-matching coupler. The component of the V self-oxygen dicing particles is expressed as a solid content ratio of 5% to 50%, preferably 5% to 5% and more preferably to 30%. If the slave oxygen ratio of the oxygen-cut particles is in the preferred range, the low-refractive-index hard-f coating layer 12 has a good surface and good optical properties such as low transparency, low refractive index, and the like. — The composition of the Shi Xitong coupling agent is the chemical formula 1 R(1), bSlX4-(4), or the VIII hydrolyzate.

The component derived from the fluorine-containing resin 15 having an alkoxyalkylene group is from 90%, preferably from 25% to 80%, and more preferably from 30% to 70%, in terms of the solid ratio. When the proportion of the component derived from the fluorine-containing resin having an alkoxyalkyl group is in the above preferred range, the obtained low refractive index hard coating layer 12 has a desired surface hardness and good optical characteristics such as low transparency. Reflectivity, etc. When the low refractive index hard coating layer 120 is formed in the present invention, a hard bismuth catalyst can be used to assist in accelerating the hardening of the coating liquid. Preferably, the hardening catalyst is a hardening catalyst which can assist in the condensation of a decane coupling agent such as an acidic compound. A preferred example of the acidic compound is a Lewis acid compound. Examples of Lewis acidic compounds are metal alkoxides such as ethyl ethoxide or metal chelates. The amount of the hardening catalyst can be appropriately selected, but it is 1 part by weight to 10 parts by weight based on 100 parts by weight of the stone smelting 17 200923406 coupling agent. In the present invention, a low refractive index hard f coating layer (10) is added, and various additives such as a polymerization inhibitor are added. "Chemical agent, dispersant, film ==: high transparency and good anti-reflection effect of the bright film. The turbidity value of the film is improved. ==::r high, _ period 10 15 In order to obtain the present invention The low-refractive-index hard coating layer 12 is well-preserved on the surface of the 'low-refractive-index hard coating layer (3). There must be fine wrinkles on the surface. The relationship between the surface roughness and the anti-retention property of the fine wrinkle surface is considered to be affected by the following machine In other words, for the finely pleated surface, when the steel wool is slid on the surface of the enamel, the steel wool contacts only the convex portion and slides, so that the contact area with the low refractive index hard coating layer 12 () is minimized as needed. As a result, the anti-surname improvement is particularly improved. The arithmetic mean roughness (Ra) of the wrinkled surface of the low refractive index hard coating layer 12 is substantially from 0.0003 μm to 〇〇25 μm, more preferably from 4 μm to 〇. _ 〇 22 μm and more preferably 004 004 μm to 〇 2 〇 micrometer. If the arithmetic mean roughness (Ra) of the pleated surface is higher than the above preferred range, the turbidity of the low refractive index hard coating layer 120 The value of the degree increases, resulting in a decrease in transparency. If the wrinkle surface is arithmetically averaged (Ra It is difficult to improve the anti-friction property in the range below the stated range. In order to form the fine wrinkle surface of the low-refractive-index hard coating layer 12 of the present invention, it is preferred that the hard coating layer 120 contains inorganic particles such as colloidal Cerium oxide, dry cerium oxide, wet cerium oxide, titanium oxide, glass beads, aluminum oxide, cerium carbide, cerium nitride, cerium oxide particles dispersed in a colloid, etc. More preferably, the hard coating 20 200923406 coating layer 120 comprises The two a bismuth telluride particles are dispersed in the colloid. In particular, it is preferred to use two or more kinds of diathenium particles of the plate diameter divergence component. For example, 丄 has an average particle diameter of 〇〇〇1 μm to 0.02. A mixture of micron and 二2 micrometers to 〇2 micrometers of dioxo-cut particles can form a fine wrinkle surface. 5 In order to allow the stacked film of the present invention to have a low reflectance on the side surface of the low refractive index hard coating layer 120, The maximum reflectance of the stacked film is required to be no more than 4.0%, and the small reflectance is not less than. If the reflectance is higher/lower than the specified range, the external light can be irradiated, and the surface of the stacked film cannot be made to have Low anti In order to make the stacked film of the present invention have a low reflectance on the side surface of the low refractive index hard coating layer 120, the product of the refractive index and the thickness of the high refractive index layer (10) and the low refractive index hard coating layer 12G is targeted. The ray (usually visible light) has a wavelength of 1/4. Therefore, four times the product of the thickness and the refractive index n of the high refractive index layer 11 and the low refractive index hard coating layer 12G is preferably 38 to 15 meters to 780. The relationship between the refractive index n and the thickness d of the preferred high refractive index layer 110 and the low refractive index hard coating layer 120 is in accordance with the following equation: (1) η · d = λ /4 > 20 where η indicates that the wavelength of visible light is usually 380 nm and $780 nm. In order to produce a stacked film of the present invention having a low reflectance, it is preferred that the thickness of the ytterbium refractive index layer 110 be from nanometers to 1 nanometer. The thickness of the low refractive index hard coating layer 120 is preferably from 0.5 to 5 μm to 1 μm, and more preferably from 0 to 07 to 0.12 μm. If the 咼 refractive index layer 11 〇 and the low refractive index hard 200923406 coating layer 12 〇 individual thickness is not within the range of the indication, the above formula cannot be satisfied. The stacked film is on the surface of the low refractive index hard coating layer 12 on the side. Does not have a low reflectance. In addition, in order to make the stacked film of the present invention have a low reflectance on the low-refractive-index hard surface of the 5-coated country side surface, the refractive index of the low-refractive-index hard f-cladding layer 12 is smaller than that of the high-refractive-index layer 110. That is, the refractive index/high refractive index layer m of the low refractive index hard coating layer 120 is preferably less than ι and more preferably from 0.6 to 0-95. The refractive index of the low refractive index hard coating layer 12 is preferably not more than 1.47 Å and more preferably 138 and 丨48. It is currently difficult to form a low refractive index hard coating having a refractive index of less than H) 1.38, and a refractive index greater than 148 results in a high reflection ratio. * When the high refractive index layer 110 and the low refractive index hard coating layer 120 are formed in the present invention, an initiator may be used to assist in the hardening of the applied binder component. 15 The initiator is used to initiate or assist the applied binder component to carry out the polymerization reaction and/or the crosslinking reaction by a radical reaction 'anion reaction, cationic reaction, etc.'. A conventional photopolymerization initiator can be used in the present invention. invention. Examples of specific initiators include sulfides such as sodium thiodithiocarbamic acid sulfonate, diphenyl monosulfide, dibenzoxazole monosulfide, disulfide, etc.; sulfur 20 ketone derivatives For example, sulfur " ketone, 2-ethyl sulphate, ketone, 2-oxathione, 2,4-diethylsulfanthene, etc.; azo compounds such as hydrazine, azobisisobutyronitrile, etc.; Diazo compounds such as diazonium salts; aromatic carbonyl compounds such as benzoin, benzoin methyl ether, benzoin ethyl ether, benzophenone, dimethylaminobenzophenone, and Michler's ketone 'benzyl Base, third butyl 20 200923406 5 10 15 20 Onion, 2-methyl fluorene, 2-ethyl hydrazine, 2-amino onion, 2 chloro onion, etc.; Amino S for benzoic acid _ for example: methylaminomethyl benzoic acid vinegar, p-dimethylaminoethyl benzoic acid s, D_methylaminobutyl phthalic acid vinegar, p-diethyl Amino isopropyl benzoyl (tetra), etc.; peroxides such as benzamidine peroxide, di-tert-butyl peroxide, dicumyl peroxide, iso-benzene benzene oxime YU pair Oxyphenyl phenyl decandyl, 9 ethionylamine amide, stupid; morphine (10) organisms such as 9,10-dimethylbenzophenone, 9-methylbenzophenone, 1 〇曱 苯 苯 啤 啥 ; ; ; ; ; ; ; ; ; ; ; ; ; ; ; ; ; ; ; ; ; ; ; ; ; ; ; ; ; ; ; ; ; ; ; ; ; ; ; ; ; ; ; ; ; ; ; ; ; ; ; ; ; ; ; ; ; ; ; ; ; ; ; ; ; ; ; ; ; ; ; ; ; ; ; ; ; ; ; ; ; Base $, 2, 4, 6_ triphenyl % read 4 fluorinated benzene, 2, 4, 6 ginseng (trichloromethyl)] # trimorphine, 3, 3, - county cold vanillin, thiometh Ketone, 2,4,6-trimethylphenylnonyldiphenylphosphine oxide, oligo(2-carbo-2-methyl-small (4-methylethyl)phenyl)-propyl n-group 2-Dimethylamino group small (4-indolyl) phenyl. butyl _ and the like. Further, when the high refractive index layer 11 and the low refractive index coating layer 120 are formed in the present invention, the amine compound can coexist in the photopolymerization initiator to prevent the initiator sensitivity from being lowered by oxygen inhibition. The amine compound is not limited to the (4) type, and may be an aliphatic amine compound or an aromatic amine compound as long as it is non-existent. Examples of the amine compound are triethanolamine, methyldiethanolamine and the like. In the present invention, the mixing ratio of the components of the weight ratio of the binder component to the particle/refractive index layer 110 is required to be from coffee to chest and from 15/85 to 25/75. If the particle content is below this range, the resulting thin chess is not very conductive, but has a desired transparency. If the content is higher than the range of #, the resulting film does not conform to f because of the physical strength of the film and the poor chemical strength of 21 200923406. The photopolymerization initiator of the present invention is usually used in an amount of from 0.1 part by weight to 20 parts by weight, based on 100 parts by weight of the binder component, and preferably from 1.0 part to 15.0 part by weight. If the content of the photopolymerization initiator of the present invention is less than 0.1 part by weight, the photopolymerization process is slow, and it may take 5 hours to obtain the desired hardness and corrosion resistance, and the film may not be completely cured.
