Self-etching dental materials based on (meth)acrylamidophosphates

摘要

A polymerizable dental material contains one or more types of (meth)acrylamide phosphate (I). A polymerizable dental material contains one or more types of (meth)acrylamide phosphate of formula (I). R 1>H or CH 3; R 2>H or 1-4C alkyl radical, and R 2>forms heterocyclic ring together with nitrogen atom and one or more atoms which belong to R 3>or R 3>'; R 3>,R 3>' : linear or branched 1-50C aliphatic radical with valency of m+n or p+n, 6-18C aromatic radical with valency m+n or p+n, or cycloaliphatic, araliphatic or 3-13C heterocyclic radical with valency of m+n or p+n, carbon chains of radical are interrupted by O, S, CONR 4>, OCONH, and R 3>, R 3>' form heterocyclic ring together with one or more atoms which belong to R 2>and nitrogen atom to which R 2>is bonded; R 4>H, 1-10C alkyl, 6-12C aryl, 6-10C aralkyl or 4-12C bicyclic radical; X : O or S; m : 1, 2, 3, or 4;and p : 0, 1, 2, 3 or 4. When p is 0, R 3>' is H. When p is 0, n is 1, 2, 3, or 4, and when p is not 0, n is 1 or 2. [Image].
