PURPOSE:To give strong adhesive property and its durability between both a compound and a material without processing acidification or the like in the case of adhesively attaching a dental adhesive correcting material e.g. bonding material, PMMA resin, etc., by mixing prescribed amounts of a polymer compound having a hydroxyl group, polymer compound having an acid radical, and an amino compound. CONSTITUTION:A primer composition contains 0.5 to 90wt.% water, 5 to 90wt.% polymer compound having a hydroxyl groups, 0.1 to 90wt.% polymer compound having an acid radical and 0.01 to 30wt.% amino compound having an acid radical. The water in use is preferable distilled water (or purified water) or ion exchange water (or deionized water). The polymer compound, having a hydroxyl group, is especially preferably polymerized monomer having unsaturated radical polymerizable with the hydroxyl group, for instance, acryloil radical or allyl radical. The polymer compound in use having the acid radical is especially preferably polymerized product of monomer having, for instance, unsaturated radical polymerizable with carboxyl radical phosphoric acid radical, etc., for instance, acryloyl radical or allyl radical. The amino compound having the acid radical is an amino compound, for instance, having carboxyl radical and carboaldehyde radical or the like. |
