Abstract:
A curable composite comprising a homogeneous mixture that has been applied to a dental surface, wherein said homogeneous mixture comprises the following components:a) an ethylenically unsaturated functional and hygroscopically functional monomer chosen from the group consisting of N-vinyl-2-pyrrolidone, vinyl acetate, vinyl methyl ether, glycidyl (meth)acrylate, N-(meth)acryl-2-imidazolidone, and acrylic monomers having the following structure:R'R""C.dbd.CR.sup.2 --CO--X--(R.sup.1 -Y).sub.q Z.sub.pwherein R' and R"", individually, are hydrogen, an alkyl of 1 to about 4 carbon atoms, monocyclic aryl or a cycloalkyl; R.sup.2 is hydrogen or an alkyl of 1 to about 3 carbon atoms; X is O, S or N--R.sup.3 wherein R.sup.3 is hydrogen, an alkyl of 1 to about 4 carbon atoms, or --R.sup.1 --Y; R.sup.1 is a divalent radical connecting Y to X; Y is OH, NR.sup.5, SH, OR.sup.6, wherein R.sup.5 is hydrogen, methylol, or methylol methyl ether, and R.sup.6 is an alkyl of 1 to about 3 carbon atoms; q is 0 or 1, provided that p is 0 when q is 1 and p is 1 when q is 0; and Z is hydrogen;b) an ethylenically unsaturated functional and hygroscopically functional coupling agent that is capable of (i) chemically reacting with and through the ethylenic bond of the ethylenically unsaturated-functional monomer of a) and (ii) chemically bonding to a surface to which the mixture is applied, wherein said coupling agent is chosen from the group consisting of aromatic substituted amino acid alkali metal salts and alkali metal salts of carboxylic acids containing at least on amino group;c) a poly-ethylenically unsaturated functional crosslinking agent that is capable of reacting with the monomer of a) above;d) a photoinitiator that induces addition polymerization of ethylenically unsaturated compounds; ande) an aqueous containing organic solvent present in the amount of 35 to 90 weight percent based on the weight of the mixture.
