PROBLEM TO BE SOLVED: To provide a dental adhesive composition exhibiting strong and stable adhesiveness to any of enamel and dentine.SOLUTION: A dental adhesive composition is obtained by mixing (A) a dihydrogenphosphate mono(meth)acrylic acid ester group-containing polymerizable monomer represented by the formula (1), (B) a hydrogenphosphate di(meth)acrylic acid ester group-containing polymerizable monomer, and (C) a polyvalent metal compound selected from at least any of polyvalent metal alkoxides, multivalent metal fluorides, polyvalent metal carbonates, polyvalent metal hydrides and alkyl polyvalent metals. [In the formula, R1 represents either of a hydrogen atom or a methyl group, and X represents a hydrocarbon group having a carbon number of 4 or more which may be straight or branched.]COPYRIGHT: (C)2015,JPO&INPIT【課題】エナメル質及び象牙質のいずれに対しても強固で安定的な接着性を示す歯科用接着性組成物の提供。【解決手段】(A)下記式(1)で表されるリン酸二水素モノ(メタ)アクリル酸エステル基含有重合性単量体と、(B)リン酸水素ジ(メタ)アクリル酸エステル基含有重合性単量体、(C)多価金属アルコキシド、多価金属フッ化物、多価金属炭酸塩、多価金属水素化物及びアルキル多価金属の少なくともいずれかから選ばれる多価金属化合物、を混合して得られる歯科用接着性組成物。[式中、R1は、水素原子及びメチル基のいずれかを示し、Xは、直鎖又は分岐していてもよい炭素数4以上の炭化水素基を示す。]【選択図】なし
