Abstract

The present invention relates to a dental composition comprising a photoinitiator system comprising a particulate carrier supporting a coinitiator covalently bonded to the surface of the carrier. Furthermore, the present invention relates to a use of the particulate carrier in a dental composition.The particulate carrier displays multiple covalently bonded tertiary amino groups and/or tertiary phosphine groups on the surface, for crosslinking monomers, oligomers and/or polymers having one or more polymerizable double bonds.
