    • A one-pact type adhesive composition for dental use which is obtained by compounding as essential ingredients a hydrophobic polymerizable monomer (a) having an acid group, a water-soluble polymerizable monomer (b), water (c), a photopolymerization initiator (d), an aromatic tertiary amine (e) having an electron-attracting group, a crosslinking polymerizable monomer (f), and a basic compound (g) which reacts with part of the hydrophobic polymerizable monomer (a) having an acid group to generate a water-soluble salt. The composition has excellent bonding strength in the bonding of a tooth, especially enamel or dentine, to a dental repairing material, especially a resinous material, and has excellent storage stability. Because the composition is of the one-pact type, no mixing operation is necessary in preparation for bonding. Furthermore, the composition has excellent bonding strength even without conducting pretreatments (etching and priming). The composition is hence suitable for use as a one-step type dental adhesive composition for conducting a tooth repair treatment through one bonding operation.
    • 通过将具有酸基的疏水性可聚合单体(a),水溶性可聚合单体(b),水(c),光聚合引发剂(d))作为必要成分配合得到的单粘合型牙科用粘合剂组合物 ),具有吸电子基团的芳族叔胺(e),交联聚合性单体(f)和与具有酸基的一部分疏水性聚合性单体(a)反应的碱性化合物(g) 水溶性盐。 该组合物在牙齿,特别是牙釉质或牙质的粘合中具有优异的粘合强度,与牙齿修复材料,特别是树脂材料的粘合,并且具有优异的储存稳定性。 因为组合物是一体型,所以在制备粘合时不需要混合操作。 此外,即使不进行预处理(蚀刻和起泡),组合物也具有优异的接合强度。 因此,该组合物适合用作通过一次接合操作进行牙齿修复处理的一步式牙科用粘合剂组合物。
