Description of the invention: L. The name of the present invention is related to a low-reflection film, and more specifically to a high refractive index comprising a second layer disposed on a substrate film. The rate of hard coating, as well as the low-reflection film of the low refractive index layer. Compared with the conventional low-reflection film, the low-reflection film can improve the surface hardness, the anti-bracket property and the fingerprint stain removal by lowering the surface roughness of the hard coat layer and the low-refractive-index layer. ability. C iltr ^ BACKGROUND OF THE INVENTION For example, CRT, LCD and PDP display devices display electrical signals on their screens, in which high voltages, which typically generate static electricity and electromagnetic waves, are used, and ambient light is reflected. On the surface thereof, it adversely affects the user's body, reduces the visual effect, and is also prone to eye fatigue. Therefore, a reflective film that can achieve a good anti-reflection effect on an object around the display device is disposed on the surface of the display device to achieve a better image sharpness in image quality, and can A screen that does not let the user's eyes get tired. In general, a low-reflection film in a display device has a multilayer structure (as disclosed in PCT No. JP2003-008535). Specific examples of the low-reflection film disclosed therein include a three-layer structure in which one of the base film is a hard coat layer, a high refractive index layer, and a low refractive index layer (as shown in FIG. 2). a series of hard coating, medium refractive index layer, high refractive index 3 201037348 layer and low refractive index layer 4 layer structure (as shown in Figure 3); and a series of hard coating, high refractive index layer A 5-layer structure of a low refractive index layer, a high refractive index layer, and a low refractive index layer (as shown in FIG. 4). The hard coat layer is provided to improve the hardness of the base film and is placed in contact with the base film. The high refractive index layer, the low refractive index layer, and the medium refractive index layer are used to adjust the refractive index and are disposed on the hard coat layer. In this case, it is important that the refractive index of the low refractive index layer is lower than the refractive index of the low refractive index layer close to the layer of the base film layer, so that the low reflection film can be used for the external environment. The light is completely reflected. Generally, a low reflection film has a multilayer structure which can adjust the refractive index. However, it is advantageous to set a smaller number of layers based on consideration of productivity, cost, and anti-reflection effect of the low-reflection film. At the same time, since the low-reflection film is disposed on the outermost side of a display device, in addition to reducing the reflection of ambient light, it also needs anti-scratch, anti-pollution protection, anti-static ability, etc. to protect The display device and polishing results. Therefore, it is known that the refractive layer has more than one function. Specific examples of the refractive layer include a high refractive index hard coat layer which is antistatic and has a function of a hard coat layer, and an anti-contamination low refractive index layer. However, when a refractive index layer having one or more functions is produced, the materials that can be used thereof are limited, and it is inevitable to select and use a very expensive material, which in turn causes a high production cost. . At the same time, the reduction in optical properties, transmittance, turbidity, and UV-resistant 201037348 line characteristics obtained by the refractive layer is disadvantageous compared to the refractive index layer produced under consideration of only the refractive index. In particular, 'for high refractive index hard coatings, a large number of particles are required' which are selected to achieve the high refractive index and antistatic properties required in a large display device, thus the hard coating The surface roughness is easy to be too large. For the low refractive index layer, a large amount of low refractive index particles are used to lower the reflection coefficient produced by the display device, and thus the surface roughness of the low refractive index layer is liable to be excessive.

The situation of placement is more frequent, and thus there is a strong need for a south surface hardness that is resistant to scratches in contact with other hard and rough materials than in the case of large display devices. [Yun] The contents of the present invention are designed to overcome the above problems and meet the needs of the art.

I [Embodiment 2 201037348 DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, the present invention will be described in more detail with reference to specific examples and drawings of the present invention. It is apparent that those specific examples are intended to exemplify the invention in more detail, and the scope of the invention should not be limited to those specific examples. The inventors of the present invention have tried to overcome the above-mentioned problems of the prior art. As a result, the refractive index of a hard 0 coating is adjusted by adding particles to a hard coating resin component to form the high refractive index hard coating in which the hard coating on the substrate film can be adjusted to have a south refractive index. When layering, we find that „ by controlling the optimum particle size contained in the hard coat layer and its content ratio, and at the same time eliminating excessive formation of the low refractive index layer disposed on the hard coat layer A factor that protrudes from the undercut, which can be produced. A reflection that can easily remove low fingerprint contamination and similar contamination, and can resist the scratching caused by the stylus, etc. Fig. 1 is a cross-sectional view of a low-reflection film according to a specific example of the present invention. The low-reflection film in Fig. 1 is a low-refractive-index hard coat 20 and a low refractive index. The layer 3 is formed by sequentially arranging on the substrate film 1 . The low-reflection film may have a smear film, an adhesive layer and a release film on opposite sides of the substrate film 1 。. According to this It provides a low-reflection film which is excellent in physical properties such as surface hardness and scratch resistance, and can reduce the arithmetic mean coarseness of a high-refractive-index hard coat layer and a low-refractive-index layer. (d) to improve the ability to remove fingerprint contamination. At the same time, according to the present invention, it provides a low-reflection film that can be produced at a lower cost, and the system 9 201037348 is typically changed by the addition of expensive metal oxides. In order to achieve the above object, the inventors of the present invention have studied and found a solution, and thus found that the object can be achieved by an antireflection film having a sequential arrangement on at least one side of a substrate film. a high refractive index hard coat layer 20 and a low refractive index layer 30, and the arithmetic mean roughness (Ra) is controlled between Ο.ΟΟΟμμηη and 〇·〇〇5μπι. According to the low reflection film of the present invention, It can be applied to an image display device by attaching it to the side of the image display side or the front side panel. Preferably, 'in the low according to the present invention The substrate film 10 in the shot film has a high transmittance and a low haze for use as an element of a display device (also referred to herein as a "display element"). For example, The transmittance in the wavelength range of 400 to 800 mn is preferably at least 40%, and more preferably at least 6%. The turbidity value is preferably not higher than 5%, and more preferably The ground system is not higher than 3%. When the film is used as a display element, if one or both of the above conditions are not satisfied, the displayed image > image may not be clear. The upper limit of the transmittance is about 99.5% compared to the range in which the production can be performed, and the lower limit of the turbidity value is about 0.1% to achieve the desired effect. 10 is not limited to a specific type, and it may be suitably selected from a resin material which is generally known as a (iv) base (tetra) film. Specific examples of the resin material of the substrate ruthenium film 10 include, having, selected from the group consisting of esters, ethylene, propylene, diacetate, triacetate, ethylene oxide, carbonate, and decyl pentene. A polymer or copolymer of a sub-monomer of the group consisting of an anthraquinone, an etherethylketone, a quinone imine, a 201037348 fluorine, a nylon 'acrylate, an aliphatic olefin, and the like. It is preferably selected from the group consisting of a terpenoid (for example, polyethylene terephthalate), an acetate (for example, cellulose diacetate), and an acrylate (for example Said polymethyl methacrylate) and the like of the group of sub-monomer polymers or copolymers. The reason for this is that the films produced by the films have good transparency, strength and thickness uniformity. Particularly, in terms of transparency, turbidity value, and mechanical properties, a base film 10 composed of a polymer having a secondary unit of an ester is preferable. Specific examples of such polyester resins include polyethylene terephthalate, poly-2,6-p-naphthalene dicarboxylate, polybutylene terephthalate, poly-", / 5 bis(2-lactyloxy)ethene _4,4'-di-ortho-oxyethylene, and the like, in these polyesters, it can be 2% molar or Less dicarboxylic acid component or diol component is copolymerized. In these typical polyester resins, quality, economic efficiency and similar factors are usually considered, while polyethylene terephthalate is particularly preferred. Preferably, one of the resins or a combination of two or more types may be used. The thickness of the substrate film 10 in the low-reflection film according to the present invention is not limited to a specific value, but It is usually 5 to 8 μm, and preferably 10 to 250 μm. The base film may be a film in which two or more films are bonded in a known manner. The substrate film 1 may be subjected to surface treatment (for example, corona discharge, glow discharge, fire) before forming the high refractive index hard coat layer 20. At the same time, in order to promote the adhesiveness, the high refractive index hard coat layer 20 may be formed by coating the surface of the base film 11 201037348 as a primer layer. (for example, coating with polyamine phthalate, polyester, polyester acrylate, polyurethane acrylate, polyepoxy acrylate, titanate compound, etc.).

Meanwhile, the shape of the cerium oxide particles is preferably spherical or hollow cylindrical. For the cerium oxide particles, it is also possible to use two or more particle components each having a different average particle diameter. The cerium oxide particles may be surface treated.

The decane coupling agent is preferably used in terms of the chemical treatment. In the solid matter ratio, the component derived from the cerium oxide particles is from 3 to 50%, preferably from 3 to 40%, and more preferably from 3 to 15%. If the ratio of the components derived from the cerium oxide particles falls within the preferred range, the resulting low refractive index 30 has a desired surface hardness and scratch resistance rating, and has, for example, transparency, low refraction.

Good optical properties with a refractive index equivalent. In forming the low refractive index layer 3 of the present invention, a hardening agent may be used to promote hardening of the coating liquid. A preferred hardening catalyst is used to effect the condensation of the lithographic coupling agent, for example, an acidic compound. A typical acidic compound of = is a Lewis acid compound. A typical Lewis compound is a metal alkoxide such as aluminum acetate acetate or a metal 21 201037348 conjugate. The content of the hardening catalyst is appropriately selected, but it is about 1 to 1 part by weight based on 100 parts by weight of the decane coupling agent. If necessary, various additives such as a polymerization inhibitor, an antioxidant, a dispersant, a leveling agent, and the like may be added in forming the low refractive index layer 30 of the present invention. In order to produce a highly transparent property in the low reflection thin web according to the present invention, it is preferred to maintain the haze value of the film below 30%, and preferably below 2.7%. If the turbidity value is higher than 3 〇%, the transparency required for the laminated film cannot be obtained. At the same time, in order to make the low refractive index layer 30 have a desired surface hardness, anti-scratch property and the fingerprint stain removal ability level, it is necessary to form fine protrusions and depressions on the surface of the low refractive index layer. Part. It is generally believed that the relationship between surface roughness, surface hardness, and bulging and concave portions is derived from the following mechanism. That means that when a piece of steel wool or the like is slid over the fine convex and concave portions, the steel wool is only in contact with the convex portion to be slid. Therefore, the larger the arithmetic mean roughness Ra is, the higher the convex portion is, and thus the steel wool sliding is hindered, so that the surface hardness and scratch resistance are lowered. As a result, the smaller the arithmetic mean roughness Ra value, the more the surface hardness and the scratch resistance can be improved. The arithmetic mean roughness value Ra of the surface of the low refractive index layer 30 is substantially between Ο.ΟΟΟΙιη and 0.025 μηη. It is preferably between Ο.ΟΟΟΙμηι and Ο.ΟΙΟμιη' and more preferably in the range between 〇 〇〇〇 1 and 0.005 μm. The arithmetic mean rough value of the surface of the low refractive index layer 22 201037348 3〇 above the specific range, for example, causes the turbidity value of the level % to increase, thus causing a decrease in transparency. In the bulge and the lower = the arithmetic mean roughness value Ra is higher than the specific range ° M main 1 will be difficult to change. Surface hardness and scratch resistance. In order to form fine convex and concave portions on the surface of the low refractive index layer of the present invention, it is preferably coated with, for example, colloidal oxygen cutting, dry oxygen (tetra), humid oxygen, and . / - Inorganic particles such as emulsified titanium, glass uncle, oxidized, carbonized stone, nitrite, etc., colloidal oxidized oxide, granules, etc. More preferably, it contains colloidal oxidized oxide particles. In particular, the fine projections and recessed portions are preferably formed of oxidized oxide particles having an average particle size ranging between 0.001 and 0.005 Å. - 4 is to make the surface of the low refractive index layer 30 of the present invention have a low & radiance, and the thickness of the high refractive index hard coat 2G and the product of the low refractive index layer 3 is preferably respectively The ground is 1/4 of the wavelength of the object's light (usually visible light). Therefore, in the hard coat layer 2 and the low refractive index layer %, the thickness and the refractive index n of the product are preferably four times between 380 and 780 nm. That is, the relationship between the refractive index (η) and the thickness (4) of the hard coat layer 2 and the low refractive index layer 3G is preferably in accordance with the range of the following Equation 1: [Equation 1] Nd= again/4, which in turn represents the visible wavelength range, which is usually 38〇nm$A S780nm°. The low-reflection thin crucible of the present invention has low reflectivity, and the thickness of the hard coat layer 2〇 is preferably 1 To 50 μm, and more preferably 2 to 30 μm. The low fold 23 201037348 has a thickness range of the irradiance layer 30 of preferably 〇 丨〇 1 to 丨〇 μηη, and more preferably 0.05 to 0.12 μπι. If the respective thicknesses of the hard coat layer 2 〇 and the low refractive index layer 3 未 do not fall within the specific range, the above formula i cannot be satisfied, and the rich film is on the side of the low refractive index layer 30. The upper surface cannot have a low reflectance. At the same time, in order to make the superimposed sheet on the side of the low refractive index layer 3 of the present invention having a low refence, the refractive index of the degradable layer is smaller than that of the hard coating 20 The refractive index, that is, the refractive index of the low refractive index layer 30 / the hard coat layer, the refractive index, is preferably less than 1.0 and more preferably from G.6 to G.95. The low refractive index layer lion has a refractive index of preferably not more than i.47, and more preferably between 14 and 145. A milk day having a refractive index of less than 14 ' will result in the arithmetic mean city value Ra of the convex and concave portions of the surface, which is increased by the increase in the amount of the granules, thereby disadvantageously reducing the surface hardness. The nature of the scratch-resistant material, in addition to the refractive index of more than 1.47 leads to a high reflectivity. Hereinafter, a method of producing a low-reflection film superior in surface hardness, scratch resistance, and loss of surface loss will be described in detail. The low-reflection film according to the present invention can be sequentially disposed on the base by a high refractive index hard coat layer 2G containing a (meth)acrylic acid vinegar compound, and a low refractive index layer 30 containing a gas compound. It is produced on at least the side of the material. In the present invention, the high-refractive-index hard coat layer 20 and the low-refractive-index layer 3G can be applied to a film on the base film by a solution in which a respective component is preferably dispersed in a -solation film. The 24 201037348 solution piano is then formed by drying and hardening the resulting film.

(Ra). The high refractive index hard coat layer in the low reflection film according to Comparative Examples 1 and 2 respectively contains an indium oxide particle (ΑΤΟ) content equal to and twice the amount in the hard coat layer, The hard coat layer is included in the paint having a hard coat resin and a photoinitiator. After hardening the layer, the arithmetic 35 201037348 average roughness value (Ra) is 〇.〇丨5 division and 〇 〇25哗, respectively. Meanwhile, the arithmetic mean roughness value (Ra) of the low refractive index layer produced by the modified lacquer is 〇〇〇3 pm and 〇〇〇5 μιη, respectively, however, as in the comparative example 1, When the arithmetic mean roughness value (Ra) is increased to 0.015 μm, the surface hardness, scratch resistance and fingerprint stain removal ability are lowered. As in the comparative example 2, when the arithmetic mean roughness value (Ra) is further increased to 〇.37μηι, the reflectance may be remarkably lowered because the refractive index will be hard with the high refractive index. The content of indium oxide particles ΑΤΟ in the coating increases and the refractive index may decrease as the hollow yttrium oxide content of the low refractive index layer increases. However, the applicability of the film as a display element is limited by the reduced sharpness in light transmission and the loss of fingerprint stain removal ability to a reduced quality. As shown in Table 1 above, the low-reflection film according to the present invention has a two-layer structure of a hard coat layer and a low refractive index layer sequentially on a substrate film, and the refraction of the hard paint The rate layer is adjusted to a high refractive index. It can be found that the low-reflection film produced according to the specific example is more resistant to surface hardness, scratch resistance and fingerprint stain removal than the low-reflection film produced according to the comparative examples. Excellent because both the high refractive index hard coat layer and the low refractive index layer have fine convex and concave portions, and the arithmetic mean roughness (Ra) of the portions is controlled. Therefore, the low-reflection film according to the present invention can be improved in physical properties as compared with the conventional low-reflection film having a multilayer structure, since it can avoid the use of expensive indium oxide particles AT〇, 36 The productivity of 201037348 can be improved and can advantageously reduce production costs. Accordingly, the present invention can provide an improved low-reflection film for a display device, which is suitable for use in a front side panel of a large flat-panel television, such as a plasma display panel, an LC TV front side panel, or a High-hardness and low-reflection film for small mobile display devices with touch screens.
