Polymerizable dental composition

Abstract

A polymerizable composition for dental use, containing monomer (a) with a polymerizable olefinic unsaturated group, acylphosphine oxide (b), organic peroxide (c), tertiary amine (d) and aromatic sulfinic acid and/or a salt thereof (e). The polymerizable composition for dental use exerts excellent curability by any of photo-polymerization and chemical polymerization, having a good color for dental use, with less color change between prior to and after polymerization, and excellent light resistance, producing a cured product with a smaller thickness of the unpolymerized layer on the surface, having larger curing depth and excellent adhesion to teeth and metals and the like and great color fastness in hot water and in darkness. By taking advantages of these excellent properties, the polymerizable composition can effectively be used for utilities, for example as a bonding agent, a composite resin, an adhesive agent, a primer and an opaque primer and the like, for dental use.
