Abstract:
An anti-glare film is disclosed. The anti-glare film comprises a poly(methyl methacrylate) (PMMA) base film and an anti-glare layer comprising an acrylic binder resin and organic microparticles, wherein the anti-glare layer comprises an miscible sub-layer adjacent to the interface between the anti-glare layer and the base film for urging the organic microparticles toward the upper portion of the anti-glare layer to form an anti-glare sub-layer with an uneven surface and wherein the average thickness of the miscible layer is at least 40 percent of the total thickness of the anti-glare layer and a ratio of the average thickness of the anti-glare sub-layer to the diameter of the microparticle is between 0.45 to 1.1.
