Patent ID: 8877287

Claim:
A method for manufacturing an anti-reflective coating film, comprising the steps of: providing an anti-reflective coating composition comprising a binder composition comprising a first (meth)acrylate-based compound and a second (meth)acrylate-based compound having a higher molecular weight than the first (meth)acrylate-based compound, inorganic nanoparticles, hollow particles, an initiator, and a solvent; applying the coating composition onto at least one surface of a substrate; drying the coating composition applied to allow at least a part of the first (meth)acrylate-based compound and inorganic nanoparticles to infiltrate into the substrate; and curing the composition to form a first layer that corresponds to the infiltrated region of the substrate, and a second layer comprising hollow particles, which covers the first layer, wherein a percentage of the cross-sectional area of the hollow particles to any cross-sectional area of the second layer is 70 to 95%, wherein the inorganic nanoparticles have a number average diameter of 5 to 50 nm, wherein the hollow particles have a number average diameter of 5 to 80 nm, wherein the refractive index of the second layer is 1.45 or less.
