ABSTRACT:
A photopolymerizable composition is described, comprising a polymerizable compound having an ethylenically unsaturated bond and a photopolymerization initiator represented by formula (I) ##STR1## wherein Z represents a non-metallic atomic group forming a nitrogen-containing heterocyclic ring; and R represents a substituted or unsubstituted aryl group or a substituted or unsubstituted heterocyclic ring. The photopolymerization initiator (I) greatly improves the sensitivity of the composition.
