Abstract:
1. A dental material comprising (a) 1 to 95 wt. % of at least one polymerizable N,O functionalized acrylic acid hydroxamide of the general Formula (I): in which A is an n+m valent linear or branched aliphatic C 1 to C 50 radical, in which the carbon chain can be interrupted by O, S, —CO—O—, CO—NH, O—CO—NH or NH—CO—NH, an n+m valent aromatic C 6 to C 18 radical or an n+m valent cycloaliphatic or heterocyclic C 3 to C 18 radical, wherein the radicals can carry one or more substituents, Y is not present, or is O, S, an ester, amide or urethane group, R 1 is hydrogen, an aliphatic C 1 to C 20 alkyl or C 3 to C 8 cycloalkyl radical which can carry one or more substituents, R 2 is H or a C 1 to C 10 alkyl radical, R 3 is not present or is a C 1 to C 16 alkylene radical which can be interrupted by O, HG is not present, or is —COOH, —P═O(OH) 2 ; —P═O(OH)(OR 4 ); —O—P═O(OH) 2 , —SO 2 OH or —O—P═O(OH)(OR 4 ), R 4 is a C 1 to C 15 alkyl radical, phenyl or benzyl radical, n is a number from 2-5 and m is 0, (b) 0 to 70 wt. % diluent monomer, (c) 0 to 70 wt. %, cross-linker monomer, (d) 0.1 to 5.0 wt. % polymerization initiator and (e) 0 to 80 wt. % filler, (f) 0 to 70 wt. % solvent, and (g) 0 to 70 wt. % adhesive monomer.
