Title:
POLYMERIZABLE MONOMER COMPOSITION FOR DENTAL MATERIAL
Document Type and Number:
WIPO Patent Application WO/2015/152220
Kind Code:
A1
Abstract:
[Problem] To provide a polymerizable monomer composition for dental material with which a hardened material having both the properties of high toughness and rigidity can be achieved, and also provide a dental material composition containing said polymerizable monomer composition for dental material, and a hardened material thereof having high mechanical properties. [Solution] A polymerizable monomer composition for dental material, said composition containing: a urethane acrylate compound (A) obtained by reacting a specific hydroxyacrylate (a1) with a diisocyanate (a2) in which two isocyanate groups are joined, via a methylene group in which a hydrogen atom may be substituted with a hydrocarbon group, with a divalent C6-9 aromatic hydrocarbon group or a divalent C6-9 cross-linked cyclic hydrocarbon group; and a polymerizable compound (B) containing at least one polymerizable group selected from a methacryloyl group and an acryloyl group, wherein the ratio of number of acryloyl groups contained in said urethane acrylate compound (A) with respect to the total number of methacryloyl groups and acryloyl groups contained in said polymerizable monomer composition for dental material is at least 10% and less than 90%. A dental material composition containing said polymerizable monomer composition for dental material.
