Abstract
Disclosed is a dental composition comprising 0.01 to 10 parts by weight of at least one kind of (a) a visible light-photopolymerization catalyst compound and one or more kinds of (b) di(meth)acrylate compounds represented by the general formula (I): wherein R1 and R2 each independently represent hydrogen or a methyl group, and a repeating unit number n of an ethylene oxide group is from 9 to 50.
Claims6
A dental composition comprising 0.01 to 10 parts by weight of (a) at least one visible light-photopolymerization catalyst compound, 5 to 70 parts by weight of (b) one or more di(meth)acrylate compounds represented by the formula (I):
- wherein R1 and R2 each independently represent hydrogen or a methyl group, and a repeating unit number n of an ethylene oxide group is from 9 to 50, and 30 to 95 parts by weight of (c) a polyfunctional monomer having three or more polymerizable functional groups.
