Abstract
A photocurable composition comprising a copolymer of maleic acid monoester with .alpha.-olefine compound, a vinylurethane compound obtained by urethanation reaction of a polyisocyanate compound with a photopolymerizable ethylenically unsaturated alcohol having a number average molecular weight of less than 3,000 or by urethanation reaction of 1 mole of diisocyanate compound with about 1 mole of the photopolymerizable ethylenically unsaturated alcohol and about 1/m mole of m-valent alcohol (wherein m is an integer of 2 to 6) having a number average molecular weight of less than 3,000, and a photosensitizer.
