(57) 【Abstract】 PROBLEM TO BE SOLVED: To develop a visible light polymerization initiator that is extremely sensitive to visible light, The polymerizable composition combined with the acrylate-based monomer improves the adhesiveness between the dental filling material and the tooth structure, and exhibits high adhesive strength. SOLUTION: A coumarin-based dye such as 3,3'-carbonylbis (7-diethylamino) coumarin, 2,4,6- Visible comprising photoacid generators such as tris (trichloromethyl) -s-triazine, diphenyliodonium hexafluorophosphate, and arylborate compounds such as tetraphenylboron sodium salt, tetrakis (p-fluorophenyl) boron sodium salt A visible light-polymerizable composition containing a photopolymerization initiator, an acidic group-containing (meth) acrylate monomer having an acidic group such as a carboxyl group and a phosphoric acid group, and the visible light polymerization initiator. |
