PURPOSE:To obtain the titled adhesive consisting of an unsaturated monomer, compound having a specific structure, alpha-ketocarbonyl compound and amine, having excellent photocuring properties in low temperature area near ordinary temperature under humid state as well as good water-resisting adhesion of cured product and useful as a dental material. CONSTITUTION:The aimed adhesive obtained by blending (A) a radical polymerizable unsaturated monomer with (B) phosphoric acid hydrogen acryloyl(or methacryloyl)oxyalkylalkoxyphenyl compound expressed by the formula (R1 is H or methyl; R2 is 2-3C alkylene; R3 is 1-2C alkyl), (C) alpha-ketocarbonyl compound and (D) amine. The component B is preferably phosphoric acid hydrogen 2-methacryloyloxyethyl 4-methoxyphenyl.
