Abstract
A self-etching, priming dental adhesive composition comprises an olefinically unsaturated monomer having an --SO.sub.3 functionality; a copolymerizable multi-functional (meth)acrylate adhesive; and a curing system. The self-etching, priming dental adhesive may further comprise a copolymerizable adhesion promoter containing an acid functionality, the adhesion promoter being different from the olefinically unsaturated monomer having an --SO.sub.3 functionality and the copolymerizable multi-functional (meth)acrylate adhesive, and a solvent system in an amount effective to dissolve the adhesive and/or the adhesion promoter. The adhesive composition provides even further advantages over the art, as all etching, priming, and application of an adhesive can be performed in one step.
