Optical film containing organic particles having narrow particle size distribution

Abstract

The subject invention provides an optical film comprising a substrate and a resin coating having a convex-concave structure on at least one surface of the substrate, wherein said resin coating comprises a plurality of organic particles and a binder, the organic particles being formed from a polyacrylate resin which comprises at least one multi-functional acrylate monomer as polymerization units, and said multi-functional acrylate monomer is in an amount from 30 wt % to 70 wt % based on the total weight of the monomers, and wherein 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.
