Abstract
Abstract PCT No. PCT/JP85/00509 Sec. 371 Date Jan. 21, 1987 Sec. 102(e) Date Jan. 21, 1987 PCT Filed Sep. 12, 1985 PCT Pub. No. WO87/01697 PCT Pub. Date Mar. 26, 1987.Disclosed herein are novel diesters of (meth)acrylic acid represented by the following formula: <IMAGE> <IMAGE> wherein the mean values of m and n are respectively 0 to 5, preferably 0 to 3, the mean value of m+n is 1 to 10, preferably 1 to 6, and R represents H or CH3. Also, disclosed herein are resin compositions comprising said diester(s) of (meth)acrylic acid, polyurethane (meth)acrylate(s), monoethylenically unsaturated monomer(s) and initiator(s) of photopolymerization as an optional component.
