Date Aug. 24, 1995Leather and skins are water repellent in aqueous emulsion in the presence of emulsifiers with polysiloxanes which are functionalized with carboxyl groups in a comb-like manner and in which the carboxyl groups are bonded to the polymer main chain via spacer groups in the form of linear or branched C2-C40-alkylene groups which may be interrupted by up to 8 non-neighboring oxygen atoms or groups of the formula -NR1-, CO- [sic] or -CO-NR1- and in addition may carry up to 5 carboxyl groups or carboxamido groups of the formula -CO-NR1R2-, where R1 and R2 are each hydrogen or C1-C4-alkyl, the spacer groups being bonded to the polymer main chain via a direct bond or via an oxygen atom or a group of the formula -NR1-, -CO-, -CO-NR1- or -CO-O-.
