ABSTRACT:
A photopolymerizable composition is disclosed, comprising a polymerizable compound having at least one ethylenic unsaturated double bond and a photopolymerization initiator, where the photopolymerization initiator is a combination of (A) acridine having a substituted or unsubstituted phenyl group at 9-position and (B) a heterocyclic compound having a thiol group connected to a 5- to 7-membered heterocyclic ring containing at least one nitrogen atom. The photopolymermizable composition is useful for preparation of lithographic plates and photoresists and as an adhesive, printing ink or coating material.
