A photopolymerizable composition containing a polymerizable compound having an ethylenically unsaturated bond, a photopolymerization initiator, and if necessary, a linear organic hibh molecular weight polymer. The photopolymerization initiator comprises a combination of (a) at least one organic boron compound anion salt of an organic cationic dye, andd (b) a compound represented by formula (I): <IMAGE> (I) wherein x represents a halogen atom; Y represents -CH3, -NH2, -NHR', -N(R')2, or -OR' wherein R' represents an alkyl group, a substituted alkyl group, an aryl group, or a substituted aryl group; and wherein R represents -CX3, an alkyl group, a substituted alkyl group, an aryl group, a substituted aryl group, or a substituted alkenyl group.
