Patent ID: 7592121

Claim:
An antireflection film comprising a transparent support, at least one hard coat layer and a low refractive index layer, in this order, wherein the hard coat layer includes a polymerized product of (A) at least one ethylene oxide or propylene oxide adduct of a tri- to hexa-functional acrylate monomer and (B) at least one tri- to hexa-functional acrylate monomer having no oxide adduct, wherein the total content of (A) and (B) is from 30 to 100% by weight, based on a total binder polymer content used to form the polymerized product, wherein the ratio by weight of (A) to (B) is from 20/80 to 80/20, and wherein the at least one monomer (B) is a mixture of dipentaerythritol hexa(meth)acrylate and dipentaerythritol penta(meth)acrylate.
