摘要

PROBLEM TO BE SOLVED: To provide a polymerizable composition forming a cured product having weather resistance, restoring property, adhesivity to a substrate and low warpage properties as a formed material.;SOLUTION: The active energy ray-curable resin composition for casting comprises a urethane poly(meth)acrylate (A) synthesized from an aliphatic polyisocyanate, a polyol and a hydroxyalkyl (meth)acrylate, an alkoxyalkyl acrylate (B) and an active energy ray polymerization initiator (C). The optical component, the key sheet and the plunger are obtained by lamination of the cured product of the composition.;COPYRIGHT: (C)2010,JPO&INPIT
