<P>PROBLEM TO BE SOLVED: To provide a photopolymerizable composition having high sensitivity, generating active radicals in high efficiency by the application of energy rays, especially light, improving the compatibility with solvents, monomers, etc., and quickly polymerizing a radically curable substance. <P>SOLUTION: The photopolymerization initiator is expressed by general formula (1) (R1 to R5 are each H or a univalent organic residue; and at least one of R1 to R5 is a (substituted)alkoxyl group or a (substituted)aryloxy group). <P>COPYRIGHT: (C)2007,JPO&INPIT |
