PROBLEM TO BE SOLVED: To provide a photopolymerizable composition having high sensitivity to laser light in the IR region and handleable under a white light. SOLUTION: The photopolymerizable composition contains (A) an ethylenically unsaturated compound, (B) a photopolymerization initiator, (C) a sensitizing dye and (D) an aromatic cyano compound having a structure of formula (III) as the basic structure. In the formula (III), Z1 and Z2 are each dicyanomethylidene or O, at least one of Z1 and Z2 is dicyanomethylidene, each quinoid ring has a substituent and such substituents may bond to each other to form a condensed ring which may have a substituent. |
