US 5,690,840 A · Method and composition for promoting improved adhesion to substrates

Abstract

An etchant primer composition is provided which includes (a) a compound hng the formula RN (CH.sub.2 YCO.sub.2 M).sub.2 (I) wherein R=R.sup.1 or R.sup.2 ; R.sup.1 =an aromatic group; R.sup.2 =a conjugated aliphatic group; Y=a single bond, CH.sub.2, CHCH.sub.3 or C.dbd.CH.sub.2 ; and each M is independently H, an alkali metal, an alkaline earth metal, aluminum, a transition or redox metal or an alkyl group having 1 to 18 carbon atoms, with the proviso that when both M groups are alkyl groups, the compound corresponding to formula I be capable of being easily hydrolyzed, displaced or exchanged with other reagents present in the etchant/primer composition and (b) a polar solvent system. An etchant/primer/adhesive monomer composition is also provided which includes the etchant/primer composition and an adhesive monomer system. One and two step simplified methods for adhering and for preparing a substrate surface, such as a dental substrate surface, to a polymeric material are also provided. Kits which may be used with these compositions and methods are also provided.
