UV-curable fresnel lens resin composition, fresnel lens, and back projection screen

摘要

The invention relates to a UV-curable Fresnel lens resin composition comprising a (meth)acrylate containing a hydroxyl group and an aromatic ring (A1), a urethane group-containing (meth)acrylate (A2) comprising an aromatic diol, an aromatic ring-containing monofunctional (meth)acrylate (A3), and a photopolymerization initiator (B) for the formation of a Fresnel lens on a sheet or plate made of a methyl methacrylate (co)polymer ; to a Fresnel lens formed by UV cure of said composition ; and to a rear projection screen including a sheet or plate carrying said Fresnel lens. The Fresnel lens has high refractive index, antistatic properties and is satisfactory in adhesion to a sheet or plate.
