| 摘要 |
The present invention provides for the use of radiation-curable coating compositions comprising at least one radiation-curable organopolysiloxane having (meth)acrylic ester groups and a photoinitiator, wherein said photoinitiator includes at least one compound of the general formula in which R<1 >is a linear or branched alkyl radical having 3 to 18 carbon atoms, preferably 4 to 12 carbon atoms, R<2 >is an alkyl radical having 1 to 4 carbon atoms, preferably hydrogen, R<3>, R<4 >are alkyl radicals having 1 to 6 carbon atoms, which may also have been linked to form a 5- or 6-membered carbon ring or one of these radicals may also be hydrogen, and R<5 >is an alkyl or alkanoyl radical, preferably hydrogen; for preparing abhesive coating materials and producing abhesive coatings.
