Patent ID: 7141298

Claim:
A hard coat film which comprises a hard coat layer formed by coating at least one face of a substrate with a coating fluid which comprises a component for forming a hard coat layer consisting essentially of (A) a compound which is formed by bonding an organic compound having a polymerizable unsaturated group to fine particles of silica, (B) an ester of (meth)acrylic acid having an alicyclic structure and (C) a compound having at least two polymerizable unsaturated groups and at least one aryl group in a molecule, wherein a polymer obtained by curing said compound (C) alone has a refractive index of 1.55 or greater, and curing a layer of the coating fluid formed on the face of the substrate by irradiation with an ionizing radiation, wherein the hard coat layer comprises 20 to 60% by weight of silica and has a refractive index of 1.53 to 1.70.
