ABSTRACT:
A photocurable composition comprises a radical polymerizable unsaturated group-bearing compound, a metal allene compound, and a squalilium compound. The composition is cured by application of low energy visible light or near infrared light having a long wavelength. In the composition, the metal allene compound and the squalilium dye serve as photopolymerization initiators, which are able to produce radicals by application of the long wavelength light and to polymerize the radical polymerizable unsaturated group-bearing compound.
