Abstract
Abstract Novel di(meth)acrylic esters represented by general formula (I) wherein m and n each represents an average number of 0 to 5, preferably 0 to 3, with m + n being 1 to 10, preferably 1 to 6, and R represents H or CH 3 . A resin composition containing this di(meth)acrylic ester, polyurethane (meth)-acrylate, monoethylenically unsaturated monomer, and an optional component of a photopolymerization initiator, is also disclosed.
