FILM FOR IMPROVING COLOR SENSE AND METHOD FOR PREPARING THE SAME

摘要

The present invention relates to a color improvement film which is made by depositing a base layer, a high refractive optical diffusion layer which includes an optical diffusion agent; a high refractive resin layer; and a low refractive resin layer on which an optical pattern is formed in order wherein the optical pattern is formed on one surface of the low refractive layer which faces the high refractive resin layer. A manufacturing method of the color improvement film includes: a step of coating a resin which includes a diffusion agent on one surface of the base layer, curing and forming the high refractive optical diffusion layer; a step of forming a high refractive resin layer, on which a plurality of optical patterns are formed in intaglio, on one surface of the high refractive optical diffusion layer; and a step for forming a low refractive resin layer on which an optical pattern is formed on one surface by coating a low refractive transparent resin on the high refractive resin surface on which the optical patterns are formed in intaglio. The color improvement film of the present invention has a low discoloration depending on a viewing angle, has excellent optical transmittance and optical diffusion property, and the manufacturing method has excellent productivity and economic evaluation.
