Claim:
Aqueous emulsions comprising: 1) 100 parts by weight of one or more liquid aminoalkyl-containing polyorganosiloxanes comprising at least 80 mol % of units of the formulae Ia, Ib II and III R 1 2 SiO (4−a−b)/2 (Ia), R 2 a R 2 b SiO (4−a−b)/2 (Ib), R 3 3 SiO (1/2) (II), and R 3 2 R 4 SiO (1/2) (III), where a is 0 or 1, b is 1 or 2, a+b is 2, R 1 are monovalent hydrocarbyl radicals having 1-40 carbon atoms optionally substituted with halogens, R 2 are either a) aminoalkyl radicals of the formula IV —R 5 —NR 6 R 7 (IV) where R 5 are divalent hydrocarbyl radicals having 1-40 carbon atoms, R 6 are monovalent hydrocarbyl radicals having 1-40 carbon atoms, H, hydroxymethyl or alkanoyl radicals, and R 7 are radicals of the general formula V —(R 8 —NR 6 ) X R 6 (V) where x is 0 or an integer from 1 to 40, and R 8 are divalent radicals of the formula VI —(CR 9 2 —) y (VI) where y is from 1 to 6, and R 9 are H or hydrocarbyl radicals having 1-40 carbon atoms, or b) in the formula IV, R 6 and R 7 combine with the nitrogen atom to form a cyclic organic radical having 3 to 8 —CH 2 — units, wherein nonadjacent —CH 2 — units are optionally replaced by units selected from —C(═O)—, —NH—, —O— and —S—, R 3 are hydrocarbyl radicals having 1-40 carbon atoms optionally substituted with halogens, R 4 are —OR or —OH radicals, where R is a monovalent hydrocarbyl radical, and wherein, in the polyorganosiloxanes, the average ratio of the sum of units of the formulae Ia and Ib to the sum of units of the formulae II and III is in the range from 0.5 to 500, the average ratio of units II to III being in the range from 1.86 to 100, and the polyorganosiloxanes have an average amine number of at least 0.01 mequiv/g, 2) at least 1 part by weight of one or more silicone resins which each comprise at least 80 mol % of units of the formulae VII, VIII, IX and X R 10 3 SiO 1/2 (VII), R 10 2 SiO 2/2 (VIII), R 10 SiO 3/2 (IX), and SiO 4/2 (X), where R 10 are hydrocarbyl radicals having 1-40 carbon atoms and optionally substituted with halogens, or H, —OR or —OH radicals, at least 20 mol % of the units are selected from units of the formulae IX and X and at most 10% by weight of the R 10 radicals are —OR and —OH radicals, 3) protonating agent, 4) at least 10 parts by weight of water, and 5) at most 5 parts by weight of emulsifier, the aqueous emulsions being storage stable for a period of at least three months at 50° C., wherein the monovalent hydrocarbyl radicals R, R 1 , R 3 , R 6 , R 9 and R 10 are alkyl radicals having 1 to 6 carbon atoms or phenyl radicals.
