Abstract
A photopolymerization initiator comprising (A) an α-diketone compound such as camphorquinone, (B1) an aliphatic amine compound such as triethanolamine or N-methyldiethanolamine, (B2) an aromatic amine compound such as ethyl p-dimethylaminobenzoate or N,N-dimethyl p-toluidine, and (C) a triazine compound substituted with a trihalomethyl group, such as 2,4,6-tris(trichloromethyl)-s-triazine or 2-phenyl-4,6-bis(trichloromethyl)-s-triazine. The photopolymerization initiator remains stable against the environmental light such as the indoor illumination light from a fluorescent lamp or the dental light illuminating the interior of the oral cavity, is excellently handled, is quickly cured by the irradiation with an intense light emitted from a light irradiator for polymerization, provides a cured body having excellent properties, can be stably preserved even at high temperatures, and is very useful as a dental composite resin.
