Photopolymerizable dental composition with suppressed change in hue by monomer

摘要

A dental composition comprising 0.01 to 10 parts by weight of at least one kind of a VIS light photopolymerization catalyst compound (a) based on 100 parts by weight of a radically polymerizable monomer containing one or more kinds of di (meth) acrylate compounds (b) and a polyfunctional monomer (c) wherein the one or more kinds of di (meth) acrylate compounds (b) are compounds represented by the general formula (I), wherein R1 and R2 each independently represent hydrogen or a methyl group and a repeating unit number of n of an ethylene oxide group 9 to 50, and wherein the VIS light photopolymerization catalyst compound (a) is 2,4,6-trimethylbenzoyldiphenylphosphine oxide, and wherein the polyfunctional monomer (c) is dipentaerythritol hexaacrylate.
