Patent ID: 7129281

Claim:
A one-bottle dental self etching bonding composition comprising, phosphoric ester and/or pyrophosphoric ester as a radical polymerizable monomer (A) having an acidic group in the molecule thereof, the radical polymerizable monomer (A) being at least one selected from the group consisting of tetra(meth)acryloxyethyl pyrophosphate and di(meth)acryloxylethyl pyrophosphate, a radical polymerizable monomer (B), a photopolymerization initiator (C), and a water-soluble organic solvent (D), wherein the bonding composition is substantially free of water, and wherein the bonding composition comprises 20 to 90 parts by mass of said water-soluble organic solvent (D) with respect to 100 parts by mass of the total sum of said radical polymerizable monomers (A) and (B).
