<p><P>PROBLEM TO BE SOLVED: To provide a curable sheet composition, which is capable of following a metal mold shape by heating and pressurizing and of polymerizing to cure by means of photoirradiation and of fixing an optical element molding pattern, and which can mold a lens pattern directly on a glass substrate or the like and is excellent in the adhesiveness to the substrate, and further has the high transparency and weatherability. <P>SOLUTION: The curable sheet composition capable of following a metal mold shape by heating and pressurizing, of polymerizing to cure by means of photoirradiation, and of fixing an optical element molding pattern, is characterized by containing 50-94% of a polycarbonate diol-modified urethane acrylate oligomer, 5-40% of a (meth)acrylate having in the molecule at least one carboxyl group and 0.5-5% of a photopolymerization initiator. <P>COPYRIGHT: (C)2009,JPO&INPIT</p> |
