However, the dry coating process is too expensive to commercially manufacture the anti-reflective film in parallel. Disadvantages, the recent wet coating process has been attempted for the manufacture of 5 s anti-reflective film and its practical commercial use. However, the reflective film produced by the wet coating process is dry coated. The scratch resistance of the manufacturer of the process will be deteriorated.

Since the reflection comes from outside The main characteristics of the light, the poor anti-reflection, the anti-pollution of external pollutants, the scratching caused by external mechanical friction, etc. In addition to these main characteristics, the surface sliding properties Recently, it has become important. If the surface sliding property is poor, when the display device is cleaned or 15 is moved to adjust a viewing angle, it is caused by friction between the frame and the antireflection film. The sound is rolled, so the user may complain. Therefore, in addition to the above-mentioned main characteristics, the antireflection film must have good surface sliding properties, and thus a further antireflection film will be required. 20 [Summary of the Invention] The present invention has been conceived to solve the above problems, and it is an object of the present invention to provide an antireflection film having excellent scratch resistance and surface sliding properties, which has excellent scratch resistance and surface.

Therefore, the antireflection film having excellent resistance to rubbing resistance and surface sliding property according to the specific example of the present day is applied to a large-sized television using, for example, an electric display panel, a liquid crystal display or the like. Side surface 5 faces. Fig. 2 is a cross-sectional view showing an antireflection film which schematically shows a stacked structure of the antireflection film. As shown in the drawing, the hard coat layer 110, the refractive index layer (hereinafter also referred to as "the conductive layer ιυο and a low refractive index layer (hereinafter also referred to as "resin layer") 13〇 The substrates are sequentially stacked on the ❹ 10 substrate film 1 (hereinafter, 100+110+120+130 is also referred to as, stacked film "). At the same time, a protective film 14 〇 and on the substrate One of the adhesion layers 15A and the release film 16A on the other side of the film 1 can be stacked. According to a specific example of the present invention, the surface slidability of the low refractive index layer is reduced by 15 In order to make the antireflection film excellent in a reflective appearance, the scratch resistance can be improved and the rubbing noise can be suppressed when the viewing angle is adjusted. Meanwhile, the reflective film is reflective The 〇 is excellent in appearance and has low surface reflectance and neutral color. 2 In order to achieve this goal, the inventors of the present invention have repeatedly conducted research and found a hard coating layer 110 and a high refractive index layer. (hereinafter also referred to as "" The electrical layer ") and the low refractive index layer (hereinafter also referred to as "resin layer") 130 are sequentially stacked on the at least one side of the base film 100 of the antireflection film, wherein at the low Among the surface friction coefficients of the refractive index layer 130, 10 200946949 has a static friction coefficient of 0.5 or less and a dynamic friction coefficient of 〇7 or less. Meanwhile, the present invention also intends to bond the above-mentioned antireflection film to one. The display device is covered by the side surface of the image or a front side panel. 5 According to a specific example of the present invention, the hard coating layer 110 containing the methacrylic acid compound includes conductivity. The high refractive index layer 120 of inorganic particles, and the low refractive index layer 130' containing the fluorine compound and/or the hollow ceria particles are stacked to form a stacked tantalum film on the base film, and The surface of the stacked film has a coefficient of dynamic friction (μΐ) of 0.7 or less, and a coefficient of static friction (μs) of 0.5 or less, whereby formation of the surface sliding property and the scratch can be improved. Resistance And a good mechanical anti-reflection film. Further, the coefficient of friction is lowered to improve the sliding property, so that the friction noise can be suppressed when the display device is moved to adjust the viewing angle. For example, the anti-reflection film It is applied to the front side surface of a large-sized television such as a flat panel of a plasma display panel, a liquid crystal display, etc. ® This is used for the excellent scratch resistance and surface sliding property according to the present invention. The base film 100' of the antireflection film preferably has a high transmittance and a low haze value to use the base film 100 as an element of the display 20 device (hereinafter referred to as ' Display element '). For example, the transmittance in the wavelength range of 400-800 nm is preferably 4 〇 0 /.戍 More ‘more preferably 60% or more. At the same time, the haze value is preferably 5% or less, more preferably 3% or less. When one or both of the above conditions are not satisfied, the resulting film used as a display element is liable to be lacking image sharpness. Meanwhile, in order to achieve the effect of satisfying the sharpness, the upper limit of the transmittance of the produceable range is about 99 5% and the lower limit of the haze value is about 0.1%. The base film 100 is not limited to a specific type. It can be suitably selected from the resin material used for the known plastic substrate film. A typical resin material for the substrate film 100 is a polymer or copolymer having the following units selected from the group consisting of esters, ethylene, propylene, diacetic acid 'triacetic acid, styrene, carbonate, A group consisting of methylpentene, sulfone, ethyl ether, quinone, fluorine, nylon, acrylic acid, aliphatic cyclic 10 olefin, and the like. Preferably, a polymer or copolymer having the following units is selected from the above-mentioned resins, and the units are selected from the group consisting of, for example, polyethylene terephthalate, such as cellulose acetate diacetate. A group consisting of, for example, polyacrylic acid methyl vinegar, acrylic acid, and the like. They are preferred because they have a very uniform light transmission, strength and thickness. In particular, the base film 100 is preferably made of a polymer having a unit of an ester, depending on light transmittance, haze value, and mechanical properties. Specific examples of such polyester resins include polyethylene terephthalate, polyethylene-2'6-naphthalene dicarboxylic acid, polybutylene terephthalate, and polyethylene-α,β-double 20 (2 gas base) Ethylene burning _4, 4, _ dinonanoic acid, and so on. Meanwhile, as long as the components do not exceed 20 mol%, the di- ortho-acid components or the diol components may be copolymerized with the poly-S. Among them, polyethylene terephthalate is generally particularly preferable in terms of quality economic efficiency and the like. It can only use one type of these constituent resin components or a combination of two or more 200946949 types. Meanwhile, the thickness of the base film 100 used for the antireflection film having excellent scratch resistance and surface 'moon 14 quality according to the present invention is not limited to a specific value. However, based on the transmittance, haze value and mechanical properties, the thickness generally falls between 5 and 800 μm, preferably between 10 and 250 μm. At the same time, the base film 1 can be produced by joining two or more films by a known method. Meanwhile, the base film 1 〇〇 may be subjected to surface treatment before forming the hard coat layer 11 (for example, by corona discharge, glow discharge, combustion 10, residual action, or coarse rotation) ,and many more). Meanwhile, in order to enhance the adhesion, the hard coat layer 11 can be applied with a coating as an initial layer (for example, polyurethane, polyester, polyester acetate, polyurethane acrylate). A coating of a polyepoxy acrylate, a titanate compound, or the like) is then formed on the surface of the substrate film. In particular, 15 can improve adhesion by applying a composition as an initial layer, and durability such as heat resistance, water repellency, and the like can be improved, and the composition contains grafted with a propylene compound to have A copolymer of the polyester resin and a crosslinking agent of a hydrophilic group to use the resulting film as a substrate film 100. The hard coat layer 110 in the antireflection film having excellent scratch resistance and surface slidability according to the present invention is produced on the base film 100. This level 110 should essentially comprise a (meth) acrylate compound. The acrylate compound is subjected to radical polymerization by irradiation with an actinic ray, and thereby the solvent resistance of the resulting film is improved or hardness. Specifically, one specific example of the mercapto acrylate compound is a monofunctional acrylate compound such as mercapto (mercapto) acrylate, n-butyl (meth) acrylate. , polyester (meth) acrylate, lauryl (mercapto) acrylate, ethyl (mercapto) acrylate, propyl (methyl) propane 5 dibasic acid ester and the like. Meanwhile, since the polyfunctional acrylate compound has two or more (meth)allyl groups which can improve solvent resistance in one molecule, it is particularly suitable for the present invention. A specific specific example of the polyfunctional acrylate compound is pentaerythritol tris(meth)acrylic acid vinegar, pentaerythritol tetra(meth)acrylate, diisopentaerythritol tris (a) Acrylate, ❹ 10 diisopentyl alcohol tetra (meth) acrylate, diisopentaerythritol penta (indenyl) acrylate S 曰, monoisodecyl hexa(hexa) acrylate, Three 曱 曱 丙 院 三 三 三 (meth) Acrylic vinegar and so on. It can only use one type of these monomers or a combination of two or more types. The constituent resin 15 for forming the hard coat layer 110 of the present invention may contain, for example, an alkyl phthalate and a hydrolyzate thereof, colloidal cerium oxide, dry cerium oxide, wet cerium oxide, or The titanium oxide or the like, and the inorganic particles of the cerium oxide particles dispersed in the colloid, improve the hardness of the hard coat layer 110 by 4. The thickness of the hard coat layer 110 is appropriately determined according to the use thereof, but is typically 1 to 5 〇μηι, preferably if the thickness of the hard coat layer is less than - Μιη, the surface hardness of this layer 11〇 will be insufficient, so the layer 11〇 may be easily damaged and therefore is not preferred. At the same time, if the thickness of the layer u 是 is more than 50 哗, the transmittance will be reduced to cause an increase in the haze value. ^The cured film 14 200946949 film will also be fragile' and will break when the hard coat layer 110 is bent. Therefore, the thickness of less than 1 μm or more than 5 〇μη is not preferable. The conductive layer 120' in the antireflection film having excellent scratch resistance and surface slidability according to the present invention is formed on the hard coat layer 120. The conductive layer 120 basically contains conductive particles - and a binder component. The electroconductive particles of the present invention include metal particles or metal oxide particles. Among them, metal oxide particles are preferred because of their © light transmission (four). Preferred metal oxide particles are 10 oxide tin (ruthenium) particles, zinc oxide particles, oxidized steel tin (yttrium) particles, oxidized/alumina particles, and cerium oxide particles. More preferably, it is indium tin oxide (yttrium) particles and antimony tin oxide (yttrium) particles. Preferably, the average primary particle size of the above-mentioned conductive particles used is not more than 〇·5 μΓη (the relative diameter of the sphere measured by the ΒΕΤ method) c 疋 more preferably between 0001 and 〇3 More preferably, it is between G.GG5 and 0.2μη1. If the average primary particle size is larger than the above size, the particles will reduce the light transmittance of the resulting film (conductive layer 120). If the size is smaller than the above size, the particles may be easily concentrated, so that the haze value of the resulting film (conductive * layer (3)) will increase. It is therefore difficult in any case to obtain the desired haze value. The binder component contained in the *H conductive layer 12G is an acrylic compound. The (meth)acrylic compound can be radically polymerized by irradiation of an active ray and is preferred because it can advantageously improve the solvent resistance or hardness of the resulting film. The one in the molecule 15 200946949

A polyfunctional (meth)acrylic compound having two or more (meth)allyl groups can improve solvent resistance and is therefore particularly preferred in the present invention. A specific example of the compound includes isopentaerythritol tris(meth)acrylic acid s, dipyridyl propyl tris(methyl) acrylate vinegar, glycerol tris(meth) acrylate, Modified tris(meth)acrylate, tris-(2-ethyl)-isocyanate tri(methyl) acrylate, etc.曰, and four including isopentaerythritol tetra(methyl) acrylate vinegar, diisopentaerythritol penta (meth) acrylate, diisopentaerythritol hexa(meth) acrylate, and the like - or more functional (meth) acrylate. 10 the binder component contained in the conductive layer 120 may have

An acidic functional group such as a carboxylic acid group, a phosphate group, a sulfate group or the like is used to improve the dispersibility of the particles. Specifically, the specific example of the monomer having the acidic functional group is, for example, acrylic acid, methyl acrylic acid, crotonic acid, 2-mercapto acetophenoxyethyl succinate, and 2-mercapto Allyl oxyethyl benzene di 15 carboxylic acid, for example, mono (2-dipropyl oxyethyl) acid sulphate and diphenylmethyl) sulphide oxyethyl y acid salt and sulphur Acetic acid from the purpose of acid (soil) acrylic acid g day and so on. In addition, it can be used - with a polar chemical bond ~ (meth) acrylic acid brewing compound, such as a chiral amine bond, a urethane bond, a bond, a stem, a °, and the like. At the same time, for example, the amino phthalate (meth) acrylate has a lysine-based resin which is particularly preferably dispersible, has a high polarity and can cause good granules, i.

In the present invention, the mixing ratio of the components of the conductive layer 12〇 The ratio of the binder component to the particles required is from 10/90 to 30/70', preferably from 15/85 to 25/75, based on the weight of 15%. If less than the above specific value is used, In the case of particles, the resulting film will have sufficient light transmission but will have a poor conductivity. When less particles than the above specified values are used, the resulting film will disadvantageously have poor physical and chemical strength. Phase '° for 100 parts by weight of the binder component, the added photopolymerization initiation The content of the agent is usually from 0.1 to 20 parts by weight, preferably from 1.0 to 15.0 parts by weight. If the amount is less than 1 part by weight, the photopolymerization process will be slow and need Long-term illumination to meet the required hardness and abrasion resistance, and the resulting thin enamel sometimes remains uncured in 200946949. On the other hand, if the added content is more than 20% by weight, the conductivity, abrasion resistance, weather resistance and the like of the film are reduced. The basic composition of the conductive layer 120 in the antireflection film having excellent scratch resistance and surface slidability '5 f according to the present invention is an adhesive component, conductive particles, and photopolymerization Starting agent. If necessary, additives such as a polymerization inhibitor, a curing catalyst oxidation inhibitor, a dispersing agent, a leveling agent, and a cerium oxide coupling agent may be added. In the present invention, the conductive layer 120 may further contain a conductive polymer such as poly-lalo and poly-amine, and the like, and an organometallic compound such as a metal complex and a chelate. The composition of the conductive layer 120 is provided with conductivity. Meanwhile, the conductive layer 12〇 may further comprise, for example, an alkyl citrate and a hydrolyzate thereof, a colloidal ruthenium oxide, a dry ruthenium oxide, a wet ruthenium dioxide or a titanium oxide, etc. Inorganic particles such as cerium oxide particles in the medium to improve surface hardness. In order to provide a desired degree of antistatic ability in the manner of a conductive layer, the surface resistance of the conductive layer 120 is preferably 20 x 1 〇 U 〇 hm / sq or less. More preferably, it is lxlO'hm/sq or less. The total transparency of the electroconductive layer 120 of the present invention is preferably 40% or more, more preferably 60% or more in terms of sharpness and light transmittance. Meanwhile, the resin layer 130 of the antireflection film having excellent scratch resistance and surface slip according to the present invention is provided on the conductive layer 120 and substantially contains fluoride. The fluorides used in the present invention are preferably those which are crosslinked by thermal energy or free radiation. The crosslinked fluoride may be a fluoropolymer having a crosslinked-5 group or a fluorine monomer having an unsaturated group, or a fluoromonomer and a crosslinking group. Fluoropolymer of monomer units. Specifically, the vapor compound is preferably composed of a fluoropolymer having a - structure in the main chain. Preferably, the fluoropolymer has a gas smouldering chain wherein the fluorine content is 3% by weight or more, i. The number of dilute conversions is one or more average molecules, preferably one. 〇 or more. These fluoropolymers are obtained by polymerizing a cured composition having a fluorine-compound and a sulphur compound, preferably by including the fluoro-glycol compound, and the fluoroolefin compound. The cured component of the copolymerized vinyl ether compound and the reaction-modified emulsifier to be mixed if necessary are obtained by polymerization. The cured composition is preferably used to form the fluoropolymer having 3 as a reactive emulsifier. By making it. The hydrazine reaction emulsifier is applied to the gas polymer contained in the coating liquid, and is applied in a flat manner. One of the reactive emulsifiers is particularly preferred as a nonionic reactive emulsifier. The unit derived from the dilute composition component of the (4) polymer in the transesterified layer η() towel is from 2〇 to 7〇 mol%, preferably from 25 to 65 mol%, more The good land is 30-60 mol%. If the ratio of the unit derived from the fluoroolefin compound component is 20 mol%, the gas content 20 200946949 ° in the obtained final copolymer will be too v. Therefore, the refractive index of the resin layer 13〇 will then become insufficient. (10) In one aspect, if the ratio of the single-derived from the fluoroolefin compound component is greater than 7Q mol%, the uniformity in the coating liquid will also deteriorate j, and thus the system is less likely to form. _ Uniform coated film. At the same time, it is also disadvantageous in that it is difficult to achieve the desired light transmittance and adhesion to the shawl substrate. In the fluoropolymer, it is derived from the formation of the ether ether structure. The unit of the substance is 10 i 70 mol %, preferably I5 to : mol / 〇, more preferably 3 〇 to 6 〇 mol %. If the unit derived from the compound containing the S-key, ', and the structure is less than 10 mol%, the uniformity in the liquid of the coating 10 will be deteriorated, so that it is not easily formed - uniform Coating the thin medium. The resin layer 130' obtained with a coating liquid having a ratio of more than 70 mol% does not have the optical properties of the desired light transmittance and antireflection. For the component of the compound containing the monovinyl ether structure, the 15 system preferably uses a monomer containing a reactive functional group such as a hydroxyl group or an epoxy group, and thus the resulting cured resin When the composition is used as a coating liquid, the strength of the cured film can be improved. The ratio of the entire monomer to the monomer comprising the hydroxyl or epoxy group is from 0 to 20 mol%, preferably from 1 to 20 mol%, and more preferably from 3 to 15 mol%. If the ratio is more than 20 mol%, the resulting resin layer will have poor optical properties, and the cured film will become weak. For a copolymer containing a reactive emulsifier, the ratio of the unit derived from the reactive emulsifier component is usually from 〇 to 丨〇 mol%, preferably from 0.1 to 5 mol%. . If the ratio is more than 1% by mole, the resin layer 130 produced by the 21 200946949 is adhesive, so it is difficult to handle the layer 130' and because the moisture resistance of the coating liquid is lowered, it will not be - a preferred resin layer. Meanwhile, the low refractive index layer 130 contains a binder resin in an amount of from 5 to 5 parts by weight based on the weight of the binder resin, and is 15 to 25 parts by weight of hollow cerium oxide. If the hollow cerium oxide particle content is less than 15 parts by weight, the refractive index is thereby increased to deteriorate the antireflection property, that is, the reflectance will increase. On the other hand, if the hollow cerium oxide particle content is more than 25 parts by weight, the roughness of the surface is thus increased to reduce the surface sliding property, and the expensive hollow cerium oxide is also caused. Increase in production costs. In addition to the fluoropolymer, it is preferred to mix a crosslinking compound to produce the resin layer 130 according to the present invention. This is because it can effectively provide some curing ability to improve the curing properties. 15 For example, 'a specific example of the above cross-linking compound is an amine-based compound' or a hydrogen-containing compound such as isopenic tetraol, polyphenol, diol, alkyl sulphuric acid, and the like A compound of an oxy group.
