Title:
POLYMERIZABLE DENTAL MATERIAL WITH PHASE TRANSFER CATALYST
Document Type and Number:
Japanese Patent JP2016166201
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a polymerizable dental material which achieves sufficient curing and thus an improved adhesive bonding and simultaneously, a long shelf-life of the paste like masses (more than one year, preferably two or more years) at a boundary layer to all adhesives, in particular all-in-one adhesives and priming+bonding systems.SOLUTION: The invention relates to the polymerizable dental material containing a catalyst paste (A) and a base paste (B), wherein the catalyst paste (A) contains at least one organic peroxygen compound, at least one radically polymerizable organic (meth)acrylic monomer and at least one filler, and wherein the base paste (B) contains at least one radically polymerizable organic (meth)acrylic monomer, an amine as co-initiator of the radical polymerization, at least one filler and at least one salt-like, water-soluble, powdery reduction agent dispersed therein, wherein the catalyst paste (A) and/or the base paste (B) contains at least one phase transfer catalyst selected from the group consisting of ammonium, phosphonium and/or sulfonium salts containing an inorganic or organic anion, provided that the phase transfer catalyst--in the event of organic anions--contains only those having 1-4 carbon atoms, and that anions of sulfinic acids are precluded.SELECTED DRAWING: None
