Abstract:
A water-soluble or water-dispersible polyurethane or a salt thereof comprisingA) a water-soluble or -dispersible polyurethane prepolymer having terminal isocyanate groups formed from a) at least one compound containing two or more active hydrogen atoms per molecule selected from diols, diamines, aminoalcohols, polyetherdiols, polyesterdiols each with a number average molecular weight of up to 3000, or mixtures thereof, wherein if the at least one compound of component a) comprises a polyesterdiol then the polyesterdiol is the reaction product of an aromatic dicarboxylic acid and an aliphatic dicarboxylic acid and an aliphatic diol, b) at least one compound different from the at least one compound of component a), containing two or more active hydrogen atoms and at least one ionogenic or ionic group per molecule which is a carboxylate group or nitrogen-containing group, wherein if the at least one compound of component b) contains a nitrogen-containing group, then the at least one compound of component b) is selected from the group consisting of whereR1 and R2 are identical or different and are C2-C8-alkylene, R3, R6 and R7 are identical or different and are C1-C6-alkyl, phenyl or phenyl-C1-C4-alkyl, R4 and R5 are identical or different and are H or C1-C6-alkyl, o is 1, 2 or 3, and Xâˆ’ is chloride, bromide, iodide, C1-C6-alkyl sulfate or SO42âˆ’/2, and c) at least one diisocyanate selected from isophorone diisocyanate, methylenediphenyl diisoscyanate or toluylene diisocyanate, and B) at least one primary or secondary amine having at least one ionogenic or ionic group; wherein component a) comprises an amount up to 50% by weight, based on the overall weight of components a) and b), of a silicone compound of the formula where R8 and R9 are identical or different and are C1-C4-alkyl, benzyl or phenyl, the radicals X are identical or different and are OH or NH2, m is 2-8, and n is 3-50.
