[New content] The main purpose of this creation is to provide an optical film with optical anti-glare and mechanical strength. Another purpose of this creation is to provide an optical film that expands the range of reflectance of inorganic oxides to cover more different applications of inorganic oxides. The purpose of this creation is to provide a kind of photoluminescence film, which can be used for the diameter of inorganic oxide particles. Another purpose of this creation is to provide an optical film to increase the light-dark contrast of its anti-glare film to provide better anti-glare contrast strength and anti-glare function. 'In order to achieve the above purpose, the present invention proposes an optical anti-glare film including: a transparent substrate; and, an anti-glare compound is coated on the transparent substrate, and the anti-glare character composition is included in the transparent which can be hardened by UV light In the resin solution, an organic-non-nucleus particle made of an inorganic oxide particle as the main body and coated with an organic acrylic monomer silanol coupling agent is added.

Many patent documents have used the scattering characteristics of light sources inside the light source to achieve optical anti-glare functions, such as Dainippon Printing and Parkhurst & Wendel φ LLP etc., they use more than one type The dispersible transparent organic particles or transparent inorganic particles are doped and added to the transparent organic resin plating solution and prepared after UV baking process. The added transparent organic particles or inorganic particles are hardened for commercial use. (sintering) processed particles, the particle diameter range is between 丨 to. In order to achieve an effective anti-glare function, the difference in reflection coefficient between each particle, The difference between the reflection coefficient of fine particles and organic resin is limited to the range of 0.03 to 0.2. Generally, the reflectance range of acrylic organic resin is generally between 149 and 153. Therefore, the reflection coefficient of organic fine particles or inorganic fine particles If the difference between the reflection coefficient of the light-transmitting particles is less than G. Q3, the number of reflection coefficients is less than G. Q3, the anti-glare effect caused by the scattering of light particles is not good, and the reflection coefficient of light-transparent particles The difference value is greater than 0.20 '. Light-transparent particles are likely to form filaments, and mist-like defects will be formed after coating. · This creation is based on the light-transparent acrylic resin nanoparticle solution, added to the view. 7 f Ming inorganic-organic mixed particles. Inorganic 'organic ready-made particles are composed of inorganic oxide micro-appearance particles', such as TiO. 2 · 2), the diameter of the mixed particles should not be designed to be too large, so as to avoid the formation of haze after the mineral film. If the scale of the inorganic oxidized particles is small, for example, = 3 (n = 1.65) ′ SiO 2 (㈣ · 42), the diameter range of the mixed particles will have a wide sigh space. Most of the electroless plating solutions used in Meguro's commercially available AG (anti-glare) films are prepared by hydrolysis of metal compounds. The refractive index range of inorganic oxides is in the range of 1.45 to 2.20, and the diameter of inorganic oxides is in the range of 2Qnm to m. The difference in reflectance between inorganic oxides is in the range of g.qi to q · 75. The range of the reflectance of the mixed particles in the range of _nm to 丨 _ is in the range of 1.5G to 1.8G. Commercial inorganic fine particles with a high reflectivity of inorganic oxides with a solid content of 61% to _ or more are used. The particle diameter distribution of _ to 3 / zm is the most common. Inorganic particles make up the majority of the cost of the ag electroless plating solution. The composition of the AG chemical plating solution created by this invention, the solid content of inorganic particles only occupies the range of 10% to 60%, and most of them are distributed in the range of 10% to 20%. The type of inorganic oxide particles used is also wide. AG film The coating thickness is thinner, which has great market competitiveness for reducing the cost of the electroless plating solution.
