Adhesive composition for dental use

A dental adhesive composition, comprising:

• a phosphoric acid group-containing polymerizable monomer,
• wherein the phosphoric acid group-containing polymerizable monomer comprises:
• a dihydrogen phosphate monoester group-containing polymerizable monomer represented by formula (1);
• a hydrogen phosphate diester group-containing polymerizable monomer represented by formula (2);
• and
• a phosphoric acid tetraester group-containing polymerizable monomer represented by formula (3),
• where R1, R2, R3, R4, R5, R6, and R7 each independently represent a hydrogen atom or a methyl group, and X1, X2, X3, X4, X5, X6, and X7 each independently represent a linear or branched hydrocarbon group having 8 to 16 carbon atoms, wherein the hydrocarbon group optionally has a hydrocarbon chain with one or more groups selected from the group consisting of an oxy group, a sulfide group, and a phenylene group.
