DENTAL MATERIAL AND COMPOSITION
Document Type and Number:
WIPO Patent Application WO/2002/034207
Kind Code:
A1
Abstract:
A dental material containing a sulfur-bearing unsaturated carboxylic acid ester compound which bears both a sulfur -containing substituent and at least two (meth)acrylic acid residues bonded to secondary or tertiary carbon atoms through oxygen, more specifically, a dental material containing a polymerizable monomer represented by the general formula (1): (1) [wherein R¿11? is a divalent organic group; X¿11? is oxygen, sulfur, -COOH-, or (CH¿2?)¿q?X¿12?- (wherein X¿12? is oxygen or sulfur; and q is an integer of 1 to 3); R¿12? is hydrogen or alkyl; R¿13? is a sulfur-containing substituent; and R¿14? is hydrogen or methyl]. The dental material and dental compositions containing the same are excellent in X-ray opacity, transparency, curing properties and stain resistance, and little cause volume shrinkage during polymerization.
