Description

200844476 IX. INSTRUCTIONS: I [No. No. shanghai huji ^_才支冬好冷页] Field of the Invention The present invention relates to an anti-glare property of a transparent substrate which can be imparted to various transparent plastic films, transparent plastic sheets, and 5 glass. An anti-glare coating composition and an anti-glare film having an anti-glare layer formed by coating the composition with the anti-glare property. L '才支冬恃】 BACKGROUND OF THE INVENTION Liquid crystal display devices (liquid crystal displays) have the advantages of thinness, light weight, low power consumption, etc., and can be used in various computers, word processors, televisions, mobile phones, personal digital assistants, and the like. In the field. In such liquid crystal display devices, an anti-glare (AG: Anti Glar > e) film which roughens the surface is provided on the surface of the display. By providing an anti-glare film on the surface of the display, the external light can be diffusely reflected by the irregularities on the surface of the anti-glare film, thereby blurring the outline of the image reflected on the display surface 15. According to this, the visibility of the reflected image on the surface of the display can be reduced, and the visibility of the picture caused by the reflection of the reflected image when the display is used can be eliminated. As a method for producing an anti-glare film for improving the display performance of a liquid crystal display device, a method of roughening the surface by processing such as cutting, press molding, or 20-bonding during film production is generally mentioned, or A method in which a layer containing a resin particle is placed on a film to coarsen the surface of the film, and the like. The latter is widely used, that is, a method of providing a layer containing resin particles on a film. Japanese Patent Laid-Open Publication No. Hei 2-2216 (Patent Document No. 5 200844476, which contains an anti-glare film having an anti-glare layer containing a light-transmitting resin and a light-transmitting fine particle, which is light-transmitting. When the refractive index difference between the resin and the light-transmitting fine particles is 0.3 or less, and the light-transmitting resin protrudes from the surface of the anti-glare layer 〇·1μιη to 〇.3, 111, when the anti-glare film is produced, For example, the microparticles used in 5 are not uniformly dispersed. In order to make the resin evenly divided into months; in the solution, it is necessary to control and adjust the viscosity of the solution, etc. If the microparticles are not uniformly dispersed, they are agglomerated, and the surface is agglomerated. The uneven shape on the upper surface will exceed the desired range, and the sharpness of the penetrating image is lowered, resulting in an undesired condition such as whitening. 1) On the other hand, when the film is manufactured, it is cut, pressed, and attached. When the surface is roughened by the processing of the surface, it is not easy to randomly set the rough unevenness, and thus the unevenness is generated according to a certain rule. The concave and convex follow a certain rule, and the light reflected on the concave surface will interfere with each other. However, the reflection light or the ridge pattern may be enhanced to cause an undesired shape 15 on the display of the display. That is, the arrangement direction of the fine concavo-convex structure of the anti-glare layer is repeated with the pixel secret direction of the display device. The reason why the texture pattern is generated. When the pixels are regularly arranged, the fine concavo-convex structure has a tendency to easily occur in the place where the rule is repeated. Further, when the anti-glare layer is formed by press forming, it is necessary to prevent The procedure for pressing the glare layer and the procedure for cleaning the peppers used for the pressing of the glare layer are complicated, and it is necessary to pay attention to not allowing foreign matter to adhere to the molding surface of the mold used for the pressing procedure. In Japanese Laid-Open Patent Publication No. Hei 2 No. 4,917, the entire disclosure of which is incorporated herein by reference, which is incorporated herein by reference, which is incorporated herein by reference to the entire disclosure of the entire disclosure of The arrangement direction of the structure, 6 200844476 is 2 2 · 5 r ± 12.5 ° C with respect to the absorption axis direction or the transmission axis direction of the polarizer. As shown here, the fine concave is set by processing. In the case of a convex structure, it is necessary to finely adjust the angle of the arrangement direction, which complicates the manufacturing process. It is also considered that the pixels of the display element become smaller and the ripples are generated due to the high definition and colorization of the display surface. The probability of the pattern will become higher. Therefore, there is a need to have a technique for solving the problem.

The reflector is constructed by disposing at least one type of wax portion in a dispersed manner to include a resin layer formed by forming irregularities. However, these substrates or reflectors are not considered to be completely reflective of the image reflected on the surface of the display, 15 penetrating image sharpness, white turbidity, and the anti-glare film that pays attention to such performance. The topics are not the same. With the advancement of technology in recent years, liquid crystal display units have been mounted on various devices that do not have a liquid crystal display unit in the past. These devices are excellent in antifouling properties and the like depending on their use. Therefore, in addition to the image-preventing function of the reflected image, etc., an anti-glare film excellent in antifouling property is increasingly required.

Therefore, in the presence of each of the azo polyoxyalkylene compound and various vinyl monomers, the heating or irradiation of the active energy ray can be supplied to the sessile group from the basal species. It is thereby possible to easily prepare a copolymer comprising a polysecond oxygen burnt section. The photoreactive oxiranic acid acrylic copolymer can be easily prepared by using the above-mentioned azo-containing (tetra)-containing compound. The content of the 1% compound and/or the compound of the compound of the privately-applied coating composition is preferably relative to the total amount of the first domain component and the second component-rereading. Fine material [weight 2 factories may not be able to find anti-fouling doubts. And the content exceeds i. Although the weight can be obtained, the antifouling property can be obtained, and the optical properties and the physical properties of the coating film are lowered. In addition to the first component and the second component, the coating composition of the present invention can improve the antifouling property of the obtained antiglare film by containing a fluorine compound and/or a siloxane compound. Further, the coating composition of the present invention further has such an amazing characteristic that the unevenness on the surface naturally generated in the obtained antiglare film is more fine and dense. The anti-glare film obtained by the coating composition of the present invention has fine unevenness by this, and thus has excellent performance without causing speckle, in addition to preventing reflection of reflected images. In addition, the so-called speckles are visible in the white enamel surface due to the whiteness of the whiteness 10 . In the fine-grained liquid crystal display device, the distance between the light rays generated by the liquid crystal becomes finer. Therefore, due to the uneven portion of the display device, diffuse reflection of light is caused, which causes a change in the amount of light to cause generation of speckle. The speckle has a problem that causes the viewer's eyes to view the display device to be tired. 15 The reason why the anti-glare film having finer and dense unevenness can be obtained by the anti-glare coating composition of the present invention is not limited to the theory, and the inventors of the present invention believe that there are fluorine-based compounds and/or oxoxane. Since the compound is separated, the phase separation state of the first component and the second component changes, whereby the formed irregularities can be further finely densified. 20 Nanoparticles The coating composition of the present invention may contain, in addition to the first component and the second component, a fluorine-based compound and/or a siloxane-based compound, and may be selected from the group consisting of inorganic nanoparticles. And at least one nanoparticle of organic nanoparticle. Examples of the nanoparticles include inorganic nanoparticles 22 200844476 particles such as glutinous nanoparticles, and organic nanoparticles such as acrylic acid and polyester. The generation of speckles can be further suppressed by adding the nanoparticles in the call. In this specification, the L-series is based on the meaning of ultra-fine particles in the super-fourth column. It is more commonly referred to as "microparticles", that is, particles having a particle diameter of several to ΙΟΟμηη, and the particle diameter is smaller. The metal oxide nanoparticles preferably have an average particle diameter in the range of (8) nm. The average particle size can be obtained by calculating the particle diameter by averaging two images obtained by a transmission electron microscope (TEM) or the like. In addition, the unevenness on the surface of the anti-glare film obtained by the coating of the composition of the first group is caused by the difference in physical properties between the second component and the second component, and is naturally generated unevenness. The shape of the nanoparticles of the erecting component is not due to the unevenness formed by precipitation on the surface of the film. Method for controlling anti-glare coating composition The coating composition of the present invention can be prepared by reacting a third component, a second and eight fluorine-based compound and/or a siloxane compound with a solvent.

These photopolymerization initiators can also be used in combination with a photosensitizer which is generally used. For example, when the second component and the second component have an unsaturated double bond, it is preferred to use a monohydroxy-cyclohexyl phenyl ketone or a 2-methyl-1 [4-(indolyl)phenyl]-2 Morphine_propane-i-ketone, benzyl 5-alkylacetone, i-(4-dodecylphenyl)-2-hydroxyl-2-methylpropane-1-one, 2-hydroxy-2-indenyl Photo-radical polymerization initiation of 1-phenylpropane-i-dione, i-(4-isopropylphenyl)-2-hydroxyl-2-ylpropanepropanone, diphenyl fluorenone, etc. Agent.

Antimony film, polyacrylic resin film, polyurethane resin film, polyester film, polycarbonate film, polysulfone film, polyether film, polymethylpentene film, polyether methyl ketone film, (meth) acrylonitrile Membrane and the like. Trivinyl cellulose is preferably used as the transparent substrate. The refractive index of trivinyl cellulose is about 148. Trivinyl or retinoic acid can be widely used as a protective film for protecting a polarizing layer of a polarizing plate. 25 200844476 Therefore, an anti-glare film obtained by using a transparent substrate can be directly used as a protective film. Further, the thickness of the transparent substrate can be appropriately selected depending on the use, and is generally used in an amount of from 25 μm to ΙΟΟΟμηι. The anti-glare layer can be formed by coating the above-mentioned anti-glare coating group on the transparent substrate. The coating method of the coating composition can be selected in a timely manner according to the conditions of the wave composition and the coating procedure, and each of the Gekoukou J fine is coated by dip coating, air knife coating, curtain coating. The method, the roll coating method, the wire (wirebar coating method, the gravure coating method, and the extrusion coating method (this method is described in the method of U.S. Patent No. 2,681,294), etc. are applied. The thickness of the glare layer is not particularly limited, and can be set in a timely manner in consideration of various requirements. For example, the coating composition can be coated to have a dry film thickness of Ο.ΟΙηηι to 20μηι. Coating film coated on a transparent substrate It can be directly hardened, or it can be dried before it is hardened, and the phase is separated before being hardened. 15 When the film is dried before being hardened, it can be 30 ° C ~ 20 (TC, It is preferably 40C to 150C' and 0. 1 to 60 minutes, and preferably dried in minutes to remove the solvent and pre-separate.

The wavelength of the irradiation light is not particularly limited and can be used. 26 200844476 Irradiation light of wavelengths below 360 nm. For example, when 2-methyl-ι[4 - (methylthio)phenyl b 2,throne ketone-dipyridinium is used as a photoinitiator, the irradiation light should be irradiated. It is preferable to have light having a wavelength near M 〇 nm and further to illuminate light having a wavelength of around 36 〇 coffee. Such light can be obtained by using an ultrahigh pressure mercury lamp or the like 5. By irradiating such light, phase separation can be produced. Hardening. Phase separation by irradiation of light has the advantage of avoiding surface shape unevenness caused by drying spots of the solvent contained in the coating composition. Thereby the coating film obtained by coating the coating composition is obtained. Hardening, or hardening of the coating film, can form an anti-glare layer. When the mixture of the bismuth component and the second component is thermosetting, it can be 4 (TC to 280 ° C, preferably 80 ° C to 250 C, and 0.1 to 180 minutes, and preferably 1 to 60).

In particular, in the invention of the present invention, since the resin particles are not contained, a high total light transmittance can be achieved as described above. The total light transmittance (Tt (%)) is measured by measuring the incident light intensity (τ 〇 ) with respect to the anti-glare film and the total transmitted light intensity ( Τ 1 ) of the anti-glare film, and can be obtained by the following formula. A schematic illustration of the full light transmittance is shown in Fig. 2. 27 200844476 [Number 4] Τΐ (%) = -ί1χ1〇〇

When the irregularities on the film are formed by the shape of the resin particles or the like, a large number of resin particles are generated during the preparation of the anti-glare film, and the value of Ra is increased due to the aggregation. When the Ra of the anti-glare film exceeds Ιμηι, the sharpness of the image penetrating the anti-glare film is lowered, and there is a concern that the white spot is unsatisfactory, which is not preferable. The arithmetic mean coarseness (Ra) of the roughness curve is the parameter specified in 〇8 β〇6〇1 5 — 2001. The arithmetic mean roughness (Ra) of the thick chain curve is obtained by taking only the reference length in the average line direction of the roughness curve, and taking the γ-axis in the direction of the average line of the taken-out portion and the direction of the longitudinal magnification to When y=f(x) represents a roughness curve, the value obtained by the following formula is expressed in micro/meter (μηι).
