PURPOSE:To obtain the titled composition having a high sensitivity by incorporating a photopolymerizable initiator consisting of at least three components in which each components are at least one of specific compds. respectively. CONSTITUTION:In the photopolymerizable composition contg. a polymerizable compd. having an ethylenically unsatd. compd., and optionally a binder, and the photopolymerization initiator, the photopolymerization initiator comprises at least three components in which each component is at least one of the specific compds. of (a) merocyanine compds. shown by formula I, (b) hexa-aryl bi-imidazole or a sulfonyloxy compds. shown by formula II, and (c) alpha,beta- dicarbonyl compds. or N-phenyl glycine or thiol compds. shown by formula III respectively. The compounding ratio of preferable constituting components is the photopolymerizing initiator of 0.01-50pts.wt. each component (a), (b) and (c) respectively, 0-1,000 binder 0-10pts.wt. thermal polymerization inhibitor, 0-50pts.wt. dye or pigment and 0-200pts.wt. plasticizer on the weight basis of the composition, thereby obtaining the titled composition having a high sensitivity. |
