PROBLEM TO BE SOLVED: To obtain a photopolymerizable resin compsn. which cures by exposure to light at a higher rate than a vinyl ether compd, and is excellent in flow properties, physical properties after curing, adhesion to a metal, etc., by compounding a compd. having properly ether groups with a cationic photopolymn. initiator. SOLUTION: This compsn, is prepd. by compounding a propenyl ether compd. having propenyl ether group represented by the formula: CH3 -CH=CH-O- and a number average mol.wt. of 500 or higher with a cationic photopolymn. initiator. pref. the compd. has at least five propenyl ether groups and a main chain selected from among polyether, polyvinyl, polyester, polyurethane, polyamide, polycarbonate, and novolak main chains. Pref. the initiator is an onium salt (e.g. triarylsulfonium salt). |
