Abstract

Abstract Disclosed herein are (i) a resin composition comprising (A) a di-(meth)acrylic acid ester of a carbonate diol having an average molecular weight of 500 to 3000 or of an addition compound of the carbonate diol with an ε-caprolactone, (B) a monoethylenically unsaturated monomer and optionally, (C) an initiator of photopolymerization, (ii) a di-(meth)acrylic acid ester of an addition compound of a carbonate diol having an average molecular weight of 500 to 3000 with an ε-caprolactone and (iii) a di-(meth)acrylic acid ester represented by the formula: ##STR1## wherein R 1 represents an alkylene group having 4 to 10 carbon atoms, R 2 represents a hydrogen atom or a methyl group, the mean values of a and b are 0 to 5, respectively, the mean sum of a plus b is 0.5 to 5 and the mean value of l is 1 to 10.
