Patent ID: 7833622

Claim:
An optical film, comprising a transparent substrate and a resin coating having a convex-concave structure on one surface of the transparent 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 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 ±5% of the mean particle size; and the organic particles are in an amount from about 180 to about 320 parts by weight per 100 parts by weight of the solids content of the binder.
