The use of epoxypolysiloxanes which are modified with oxyalkylene ether groups and contain, attached to an Si atom of the epoxypolysiloxane, at least one group of the general formula (I) -R3-O-(C n H(2n-m)R4m O-)x R5 (I) in which R3 is a divalent, unsubstituted or substituted alkyl or alkylene radical having 2 to 11 carbon atoms, n is 2 to 8, m is 0 to 2n, x has a value of 1 to 200, and R4 stands for identical or different alkyl radicals having 1 to 20 carbon atoms or for identical or different, unsubstituted or substituted phenyl radicals having up to 20 carbon atoms, R5 is a hydrogen radical, an unsubstituted or substituted alkyl radical having 1 to 0 carbon atoms, an acyl radical or a radical -O-CO-NH-R6, in which R6 is an unsubstituted or substituted alkyl or aryl radical, it being possible for the oxyalkylene segments -(C n H(2n-m)R4m O-) within one oxyalkylene ether radical to be different from one another and for the sequence of the individual oxyalkylene segments -(C n H(2n-m)R4m O-) to be arbitrary, embracing in particular block copolymers, random polymers, and combinations thereof, as additives to cationically radiation-curing coatings, printing inks and/or print varnishes.
