<P>PROBLEM TO BE SOLVED: To provide a resin composition which is excellent in releasability, mold reproducibility, and adhesion to a substrate film, has high durability, and is suitable for an optical lens to be molded on a base. <P>SOLUTION: An energy ray-curable resin composition to be molded on a base contains: 30 to 70 parts by mass of a polyethylene oxide modified bisphenol-A di(meth)acrylate (A) represented by the following general formula (1) (in the formula, R<SB POS="POST">1</SB>and R<SB POS="POST">2</SB>each represents a hydrogen atom or a methyl group independently and m and n each represents a positive integer of 5 to 10 independently); 3 to 50 parts by mass of a mono(meth)acrylate (B) having a phenyl ether structure; 3 to 20 parts by mass of a polyfunctional (meth)acrylate (C) which has three or more (meth)acryloyl groups and is modified by caprolactone or ethylene oxide; 3 to 20 parts by mass of an urethane (meth)acrylate oligomer (D) having a tetramethylene glycol structure; and 1 to 10 parts by mass of a photopolymerization initiator (E). <P>COPYRIGHT: (C)2013,JPO&INPIT |
