Abstract

Polymerizable materials which contain (1) 1 to 80 wt.-% of at least one polysiloxane, (2) 0.1 to 5 wt.-% of one or more initiators for radical polymerization, (3) 0 to 60 wt.-% of radically polymerizable monomer and (4) 1 to 50 wt.-% of one or more radically polymerizable monomers which carry at least phosphonic acid group, sulphonic acid group and/or mono- or dihydrogen phosphoric acid ester group, the polysiloxane (1), the monomer (3) or both being substituted by fluorine. The materials are suitable in particular for the coating of natural or artificial teeth.
