Abstract

An aqueous organopolysiloxane-containing composition comprising organopolysiloxanes of formula I: EQU HOSi(A) (CH.sub.3).sub.z (OH).sub.1-z O!.sub.a Si(B) (R.sup.2).sub.y (OH).sub.1-y O!.sub.b Si(C) (CH.sub.3)O!.sub.c Si(D) (OH)O!.sub.d H.multidot.(HX).sub.e (I), wherein A is an aminoalkyl group of formula II: EQU H.sub.2 N(CH.sub.2).sub.f (NH).sub.g (CH.sub.2).sub.h Si(OR).sub.3-z (CH.sub.3).sub.z (II), in which 0.ltorsim.f.ltorsim.6, g=0 if f=0 and g=1 if f>0, 0.ltorsim.h.ltorsim.6 and 0.ltorsim.z.ltorsim.1; B is a fluoroalkyl group of formula III: EQU R.sup.1 --Y--(CH.sub.2).sub.2 Si(R.sup.2)y(OR).sub.3-y (III), wherein R.sup.1 is a mono-, oligo- or perfluorinated alkyl group having 1-9 C atoms, or a mono-, oligo- or perfluorinated aryl group, Y is a CH.sub.2, O or S group, R.sup.2 is a linear, branched or cyclic alkyl group having 1-8 C atoms or an aryl group and 0.ltorsim.y.ltorsim.1; C is an alkyl group of formula IV: EQU R.sup.3 --Si(CH.sub.3) (OR).sub.2 (IV), and D is an alkyl group of formula V: EQU R.sup.3 --Si(OR).sub.3 (V), wherein R.sup.3, in each case is identical or different, and is a linear, branched or cyclic alkyl group having 1-8 C atoms, and R, in each case is …
