Abstract: The invention relates to an initiator system for curing a dental composition, the initiator system comprising a hydroperoxide component, a transition metal component, a polymerizable thiourea component, the polymerizable thiourea component comprising a thiourea moiety which is attached to a (meth)acrylate moiety through a C3-11 alkyl chain. The invention also relates to a dental composition comprising such an initiator system, and curable components, in particular curable components comprising acidic moieties.

Abstract: The invention relates to a microcapsule comprising a hollow or porous core, the hollow or porous core being composed of a polymeric material and containing a component of a redox-initiator system, a shell, the shell being composed of a pH-sensitive material. The microcapsule can be used for formulating dental materials.
