The invention relates to a process for the fat liquoring/softening of leathers and furs by treatment with an aqueous dispersion of a copolymer obtainable by polymerization of a) maleic anhydride, b) C12-C30 alpha-olefins, esters of (meth) acrylic acid and/or maleic acid with C12-C30 alcohols and c) optionally, further hydrophilic, ethylenically unsaturated monomers which are copolymerizable with a) and b), reaction of the anhydride groups with monovalent alcohols comprising at least one ether functionality, and partial neutralization or hydrolysis of the resdual acid or anhydride groups and manufacture of a flowable dispersion having an active substance content of at least 40%-wt.
