Abstract
A photopolymerizable composition comprising a polymerizable ethylenically unsaturated compound, optionally, a linear organic polymer, and a photopolymerization initiator comprising a combination of a compound represented by the general formula (I) ##STR1## wherein Z represents the non-metal atomic group necessary to form a nitrogen containing heterocyclic nucleus, R.sub.1 represents an alkyl group or a substituted alkyl group, and R.sub.2 represents an alkyl group or an aryl group having a comparatively high photopolymerization initiating ability; and a compound represented by the general formula (II) ##STR2## wherein X represents a halogen atom, Y represents --CX.sub.3, --NH.sub.2, --NHR.sup.1, --NR.sup.1.sub.2 or OR.sup.1, R.sup.1 represents an alkyl group or an aryl group and R represents an alkyl group, an alkyl group substituted with at least one chlorine atom, an aryl group, a substituted aryl group or a substituted alkenyl group.
