1. A dental adhesive composition, comprising:
(A) a dihydrogen phosphate monoester group-containing polymerizable monomer of formula (1):

OG Complex Work Unit Chemistry
R1 being H or a methyl group, and X1 being an optionally substituted, linear or branched hydrocarbon group having 8 to 16 carbon atoms; and
(B) a dihydrogen phosphate monoester group-containing compound of formula (2):

OG Complex Work Unit Chemistry
being an optionally substituted, linear or branched hydrocarbon group having 8 to 16 carbon atoms,
wherein the hydrocarbon group of X1 and/or X2 optionally has a hydrocarbon chain comprising an —O—, —S—, and/or a phenylene group, and
wherein the dihydrogen phosphate monoester group-containing compound (B) is present in a range of from 0.05 to 5.0 parts by mass, relative to 100 parts by mass of the dihydrogen phosphate monoester group-containing polymerizable monomer (A).
