UV CURING RESIN COMPOSITION FOR OPTICAL DISK, AND CURED MATERIAL THEREOF

摘要

PROBLEM TO BE SOLVED: To provide a strong substrate for an optical disk having excellent mass productivity in substrate molding by a 2P method, satisfactory releasability from a stamper and a small warpage variation, upon curing and after a multilayer disk is left in a high temperature and high humidity condition by a UV curing resin.

SOLUTION: The UV curing resin composition for the multilayer optical disk contains (A) a (meth)acrylate having a fatty chain, (B) a (meth)acrylate monomer and/or (C) a urethane (meth)acrylate and (D) a photopolymerization initiator.
