(57) [Summary] [Problem] Without performing any pretreatment on the tooth material, Achieves high initial adhesive strength and excellent adhesive durability. SOLUTION: [A] A polymerizable monomer having a dihydrogen phosphate group such as mono (2-methacryloyloxyethyl) dihydrogen phosphate, and a monomer such as bis (2-methacryloyloxyethyl) monohydrogen phosphate Consisting of a mixture with a polymerizable monomer having a hydrogen phosphate group, the mixing ratio of these phosphate group-containing polymerizable monomer, And a polymerizable monomer including a polyvalent carboxylic acid group polymerizable monomer such as 11-methacryloyloxy-1,1-undecanedicarboxylic acid, and [B] a polymerization initiator. |
