Abstract
The present invention relates to a catalytic composition for photopolymerization, which comprises an alpha-diketone and a hydrazone or a silane compound which has a silicon atom carrying a hydrogen, and also relates to a photopolymerizable composition which comprises a vinyl compound capable of radical polymerization and the above catalytic composition. The catalytic composition is markedly improved in photopolymerization activity and the photopolymerizable composition uniformly cures.
