An object of the present invention is to propose a highly sensitive curable composition capable of efficiently generating active radicals by irradiation with energy rays, particularly light, and capable of polymerizing radically curable substances in a short time. . A photo radical polymerization initiator represented by the following general formula (1): General formula (1) [Chemical 1] (However, in the formula, R1 and R2 each independently represent a monovalent organic residue, and R1 and R2 may be bonded together to form a cyclic structure. R3, R4 and R5 may be Each independently represents a hydrogen atom or a monovalent organic residue.) |
