PURPOSE:To provide a photo-polymerization initiator containing an aminobenzylidenecarbonyl compound and an N-aryl-alpha-amino acid as essential components and giving a photo-polymerizable composition having high sensitivity to visible light. CONSTITUTION:The objective photo-polymerization initiator contains (A) an aminobenzylidenecarbonyl compound of formula I (R1-R4 are 1-6C alkyl; R5 and R6 are H, cyano, 2-8C alkoxycarbonyl, 1-12C alkyl or aryl; R7-R14 are H, Cl, Br, 1-12C alkyl, aryl or alkoxy; X is O, S, 1-12C alkyl, aralkyl, acyl, etc.) and (B) an N-aryl-alpha-amino acid of formula II (R15-R19 are H, 1-12C alkyl or halogen; R20 is H, 1-12C alkyl, aryl, etc.; R21 and R22 are H or 1-8C alkyl). The photo-polymerization initiator forms a photo-polymerizable composition together with an addition polymerizable compound having a boiling point of >=100 deg.C under normal pressure.
