Abstract

Radiation-curing printing inks which comprise organopolysiloxanes of the general formula ##STR1## in which R.sup.1 =an alkyl radical having 1 to 8 carbon atoms, PA1 R.sup.2 =a group of the formula EQU --CH.sub.2 --CH.sub.2 --C(O)O--R--(OC(O)--CH.dbd.CH.sub.2).sub.x-1 and/or EQU --CH.dbd.CH--C(O)O--R--(OC(O)--CH.dbd.CH.sub.2).sub.x-1 in which x is an integer and is at least 2, and R is a hydrocarbon radical which optionally has alkoxy groups, PA1 R.sup.3 =R.sup.1 or R.sup.2, PA1 n=30 to 150, PA1 m=0 to 3, preferably 0, PA1 in quantities of from 0.01 to 3% by weight, based on the ink formulation.
