Abstract: The invention concerns the use of aqueous solutions or dispersions of copolymers which are obtained by the radical copolymerization of: (a) between 20 and 90 wt % of at least one monoethylenically unsaturated C4-C6 dicarboxylic acid or its anhydride as component A; (b) between 5 and 50 wt % of at least one C2-C6 olefin as component B; (c) between 5 and 50 wt % of at least one hydrophobic comonomer selected from the group comprising the long-chain olefins, esters of long-chain alcohols with acrylic acid or methacrylic acid, amides of long-chain amides with acrylic acid or methacrylic acid and the long-chain alkylvinyl ethers as component C; and (d) between 0 and 40 wt % of further comonomers which can be copolymerized with the above monomers as component D; the total of the amounts of components A, B, C and optionally D being 100 wt %. This copolymerization process is followed by at least partial esterification or hydrolysis and neutralizing and/or reaction with bases of the carboxyl groups which occur during hydrolysis. These solutions or dispersions are used for treating leather and/or furs.
