ABSTRACT:
A photopolymerizable composition comprising an addition polymerizable unsaturated compound containing at least two ethylenically unsaturated double bonds in the molecule thereof and photopolymerization initiators, wherein a 4,4'-bis(dialkylamino)benzophenone represented by general formula I below, a benzophenone derivative represented by general formula II below and a compound having a group represented by general formula III below are contained as said photopolymerization initiators: ##STR1## wherein R represents an alkyl, cycloalkyl or hydroxyalkyl group having 1 to 6 carbon atoms or is combined with another R substituted on the same nitrogen atom to form tetramethylene, pentamethylene or oxybisethylene; ##STR2## wherein R.sup.1 represents a hydrogen atom ##STR3## X.sub.1 and X.sub.2 each represents an alkyl group, an alkoxy group, a carboxy group, an alkoxycarbonyl group, an aryloxycarbonyl group or a halogen atom; m and n each represents 0, 1 or 2 and when m and n each represents 2, X.sub.1 and X.sub.2 may be the same or different;
