CURABLE DENTAL COMPOSITION
Document Type and Number:
WIPO Patent Application WO/2019/054507
Kind Code:
A1
Abstract:
This curable dental composition is characterized in that: the composition contains a radical-polymerizable monomer component (A), a polymerization catalyst (B), and inorganic particles (C); the radical-polymerizable monomer component (A) contains a difunctional monomer (A-1) represented by formula (α): RP-SP1-RP (in the formula (α), RP is a radical-polymerizable group represented by CH2=C(R)-COO- or CH2=C(R)-CONH-, with R being a hydrogen atom or a hydrocarbon group having 1-3 carbon atoms, and SP1 being a hydrocarbon group having 5-15 carbon atoms), and the content of the difunctional monomer (A-1) in the radical-polymerizable monomer component (A) is 5-40 mass% on the condition that the content of a diluting monomer (A-2) represented by formula (β): RP-SP2-RP (in the formula (β), RP is as defined in the formula (α), SP2 is an aliphatic hydrocarbon group other than SP1, an oxygen-containing aliphatic hydrocarbon group having 2 or more oxygen atoms or an oxygen-containing aromatic hydrocarbon group having 3 or more oxygen atoms) is 0 or 10 mass% or less.
