Abstract
The invention provides a light-curable dental material comprising a polymerizable compound having at least one ethylenically unsaturated bond and a hexaaryl bisimidazole as a photopolymerization initiator.
Claims15
A light-curable dental material comprising
- (i) a polymerizable compound having at least one ethylenically unsaturated bond and
- (ii) a hexaaryl bisimidazole.
Use of a hexaaryl bisimidazole in a light-curable dental material as a photoinitiator.
Light-curable dental material such as dental composite comprising a solid particulate filler and a polymerizable matrix, wherein the polymerizable matrix comprises:
- (i) one or more polymerizable compounds each having at least one ethylenically unsaturated bond and
- (ii) a hexaaryl bisimidazole.
