Abstract
A photopolymerizable composition developable with an alkali aqueous solution which comprises a carboxyl group-containing high polymer binder, a photopolymerizable monomer, a photopolymerization initiator system and a compound of a specific structure is disclosed. The photopolymerizable composition shows a good keeping stability in a state of lamination on a metal board and thus is highly useful in the production of, for example, dry films for print basic boards, photoresists, photomasks, lithograph boards and resin relief boards.
