Dental adhesive comprising an itaconic acid monoester compound

Abstract

A novel itaconic acid monoester compound represented by the following general formula (1) ##STR1## (R.sub.1 represents --H or --CH.sub.3, and R.sub.2 represents a C.sub.2 -C.sub.10 alkylene group, an oxyethylene group or a derivative thereof). The above compound is ordinarily synthesized from itaconic anhydride and a hydroxyalkyl ester of (meth)acrylic acid. Further, the above compound has hydrophilic groups and hydrophobic groups in appropriate balance, is superior in hardness, compression strength and water absorbability, and is suitable for use particularly in a dental adhesive comprising the compound or a polymer thereof. When the compound is used in a dental adhesive, the dental adhesive shows strong adhesion to the teeth or a composite resin over a long period even under a wet condition inside the mouth, and has excellent durability.
