Abstract

The invention provides radiation-curing coating materials composed of at least one silicone resin modified with vinylalkoxysilane and vinylcyclohexene oxide and of at least one epoxy-functionalized polysiloxane and of a cationic photoinitiator. Furthermore, coinitiators may also be a constituent of the mixture, in order to obtain increased reactivity of the formulation.
