Provided are a substantially transparent adhesive composition for hard tissue, and a method for producing it. The adhesive composition exhibits good adhesiveness to hard tissue, especially to both enamel and dentin, and has the advantage of improved bonding durability especially in water. This contains (a) a water-insoluble, acid group-containing polymerizable monomer which has, in the molecule, at least one hydrocarbon group selected from an alkylene group having from 8 to 25 carbon atoms an alkyl group having from 8 to 25 carbon atoms and an aromatic group, and/or its salt, and (b) water, and has pH of from 1.0 to 6.0. This is produced by mixing (a) a water-insoluble, acid group-containing polymerizable monomer which has, in the molecule, at least one hydrocarbon group selected from an alkylene group having from 8 to 25 carbon atoms an alkyl group having from 8 to 25 carbon atoms and an aromatic group, (b) a basic compound capable of forming a soluble salt with the acid group-containing polymerizable monomer, and (c) water to thereby give a mixture having pH of from 1.0 to 6.0. |
