Patent ID: 8114499

Claim:
An optical film, comprising a substrate and a resin coating having a convex-concave structure on at least one surface of the substrate, wherein the resin coating comprises a plurality of organic particles and a binder, the organic particles being formed from a polyacrylate resin comprising at least one mono-functional acrylate monomer and at least one multi-functional acrylate monomer as the polymerization units, wherein the multi-functional acrylate monomers are in an amount from about 30 wt % to 70 wt % based on the total weight of the monomers; the organic particles have a single mean particle size; the particle size distribution of the organic particles ranges within about ±30% of the mean particle size; and the organic particles are in an amount from about 110 to about 360 parts by weight per 100 parts by weight of the solids content of the binder.
