An etchant/primer composition is provided which includes (a) a compound having the formula n n RN(CH.sub.2 YCO.sub.2 M).sub.2 (I) n n wherein R=R 1 or R 2 ; n R 1 =an aromatic group; n R 2 =a conjugated aliphatic group; n Y=a single bond, CH 2 , CHCH 3 or C═CH 2 ; and n 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. |
