A photopolymerizable composition is provided containing a polymerizable compound having an ethylenically unsaturated bond, a photopolymerization initiator, and if necessary, a linear organic high molecular weight polymer. The photopolymerization initiator comprises a combination of (a) an organic compound represented by formula (I): [Figure] (I) wherein R1, R2, R3, and R4, which may be the same or different, each represents a substituted or unsubstituted alkyl group, a substituted or unsubstituted aryl group, a substituted or unsubstituted alkenyl group a substituted or unsubstituted alkynyl group, or a substituted or unsubstituted heterocyclic group, and at least two of said R1, R2, R3, and R4 may combine to form a cyclic structure, with the proviso that at least one of R1, R2, R3, and R4 is an alkyl group, and wherein Z�represents an alkali metal cation or a quaternary ammonium cation, and (b) an organic dye having no counter anion.

A photopolymerizable composition comprising: (i) a polymerizable monomer compound in an amount such that a light-exposed portion thereof will separate from a light-unexposed portion thereof when treated with a developer, said compound having at least one ethylenically unsaturated group, which is capable of being photopolymerized by active light, and (ii) a photopolymerization initiator in an amount effective to initiate polymerization of said polymerizable monomer compound wherein said initiator comprises a combination of (a) an organic compound represented by formula (I): [Figure] (I) wherein R1, R2, and R3, and R4, which may be the same or different, each represents a substituted or unsubstituted alkyl group, a substituted or unsubstituted aryl group, a substituted or unsubstituted alkenyl group, a substituted or unsubstituted alkenyl group, or a substituted or unsubstituted heterocyclic group, and at least two of said R1, R2, R3, and R4 may combine to form a cyclic structure, with the proviso that at least one of R1, R2, R3, and R4 is an alkyl group, and where Z�represents an alkali metal cation or a quaternatry ammonium cation, and (b) an organic non-ionic dye.
