Photopolymerizable composition

摘要

A photopolymerizable composition for image formation, which comprises 30 - 95 wt. % of an unsaturated polyester having an acid value of 5 - 100 which is the condensation product of a carboxylic acid component containing more than 40 mole % of a carboxylic acid compound having the formula [I] <IMAGE> wherein R1 represents hydrogen or a C1-4 lower alkyl with a polyol component containing more than 30 mole % of a polyol having the formula [II] HO(R2O)nH wherein R2 represents C2-4 alkylene or a derivative thereof and n is an integer of 2 - 5 and 70 - 5 wt. % of a photopolymerizable unsaturated monomer and a photosensitizer.
