Abstract:
1. An antiglare film comprising a substrate; and an antiglare coating composition coated on the substrate, the antiglare coating composition comprising: a) acrylate binder resin; b) 2 to 30 wt % of inorganic fine particles selected from a group consisting of alumina, aluminum hydroxide, magnesium oxide, antimony oxide, and silica having an average particle size ranging from 0.4 μm to less than 1 μm, wherein the refractive index of the fine particles varies between 0.2 to 0.5 from the refractive index of the acrylate binder resin, based on the weight of acrylate binder resin; and c) 1 to 20 wt % of inorganic fine particles selected from a group consisting of alumina, aluminum hydroxide, magnesium oxide, antimony oxide, and silica, having an average particle size of 1 to 3 μm, wherein the refractive index of the fine particles varies within 0.1 from the refractive index of the acrylate binder resin, based on the weight of acrylate binder resin, and wherein the internal diffusion haze of the film ranges from 15 to 40 and surface haze of the film is less than 15.
