Claim:
Binder-containing colloidal aqueous dispersions, comprising: (a) organopolysiloxane(s) comprising units of the formula R 1 x Si(OR 2 ) y O (4-x-y )/2 (I) where x is 0, 1, 2 or 3 and y is 0, 1 or 2, with the proviso that the sum total x+y is ≦3, x is on average from 1.0 to 2.0, and y is on average from 0 to 0.5, R 1 in each occurrence is the same or different and is an SiC-bonded monovalent hydrocarbyl radical having 1 to 18 carbon atoms per radical, optionally including water-inert substituents, R 2 in each occurrence is the same or different and is hydrogen or a hydrocarbyl radical having 1 to 18 carbon atoms per radical which may be interrupted by one or more non-adjacent oxygen atoms, or is a radical of the formula —COCH 3 , —COC 2 H 5 or —CH 2 CH 2 OH, (b) water-soluble or self-dispersing silane-containing polyvinyl alcohol(s) and/or polyvinyl esters and/or copolymers with the proviso that more than 50 mol % of fully or partially saponified vinyl ester units are present, wherein at least one of the monomer units contains an attached silane, and with the proviso that the silanes used in the preparation of (b) are those of the formula R 3 SiR 4 a (OR 5 ) 3-a , where a is 0, 1 or 2, R 3 is CH 2 ═CR 6 —(CH 2 ) 0-3 — or CH 2 ═CR 6 CO 2 (CH 2 ) 1-3 —, R 4 is C 1 - to C 3 -alkyl, C 1 -to C 3 -alkoxy or halogen, R 5 is a branched or unbranched, optionally substituted alkyl radical having 1 to 12 carbon atoms or is an acyl radical having 2 to 12 carbon atoms, in which case R 5 is optionally interrupted by an ether group, and R 6 is H or CH 3 , or those of the general formula CH 2 ═CR 7 —CO—NR 8 —R 9 —SiR 10 m —(R 11 ) 3-m , where m is 0 to 2, R 7 is either H or methyl, R 8 is H or an alkyl group having 1 to 5 carbon atoms, R 9 is an alkylene group having 1 to 5 carbon atoms or a bivalent organic group in which the carbon chain is interrupted by an oxygen or a nitrogen atom, R 10 is an alkyl group having 1 to 5 carbon atoms, R 11 is an alkoxy group having 1 to 40 carbon atoms, optionally substituted with further heteroatoms, (c) optionally surface-active compounds, and (d) water.
