Patent ID: 8449666

Claim:
An aqueous dispersion comprising: (A) at least one organosilicon compound (A1) or a mixture of at least one of (A1) and one of (A2) where silane (A1) is of the formula RaR 2 bSi(OR 1 ) 4-a-b (I), in which R are identical or different and are monovalent, SiC-bonded, optionally substituted hydrocarbon radicals having at least 4 carbon atoms, R 1 are identical or different and are monovalent, optionally substituted hydrocarbon radicals, R 2 are identical or different and are monovalent, SiC-bonded, optionally substituted hydrocarbon radicals having 1 to 3 carbon atoms, a is 1, 2 or 3 and b is 0, 1 or 2, with the proviso that the sum of a and b is 1, 2 or 3, and/or the partial hydrolysis products thereof, and siloxane(s) (A2) comprise units of the formula R 3 c (R 4 O) d SiO (4-c-d)/2 (II), in which R 3 are identical or different and are hydrogen or a monovalent, SiC-bonded, optionally substituted hydrocarbon radical, R 4 are identical or different and are hydrogen or a monovalent, optionally substituted hydrocarbon radical, c is 0, 1, 2 or 3 and d is 0, 1, 2 or 3, with the proviso that the sum of c and d is less than or equal to 3, (B) at least one nonionic emulsifier having an HLB value greater than or equal to 14, and with one or more nonionic emulsifiers having an HLB value of less than 12, (C) at least one cationic surfactant selected from the group consisting of (C 1) compound(s) of the formula (CH 3 ) 3 R 6 (4-e) N + X − (III), and (C2) compound(s) of the formula in which R 5 are optionally substituted hydrocarbon radicals, R 6 are identical or different and are optionally substituted aliphatic hydrocarbon radicals having at least 10 carbon atoms or optionally substituted aromatic hydrocarbon radicals having at least 6 carbon atoms, R 7 are optionally substituted aliphatic hydrocarbon radicals having at least 10 carbon atoms or optionally substituted aromatic hydrocarbon radicals having at least 6 carbon atoms, R 8 are optionally substituted hydrocarbon radicals, and X − is a monovalent organic or inorganic anion, and (D) water.
