Aqueous polymer dispersions are produced by polymerizing monoethylenically unsaturated monomers bearing acid groups in an acid, partially or totally neutralized form, optionally with other monomers that can be copolymnerized therewith in the presence of hydrophilized vegetable, animal and/or synthetic fats or oils. Also disclosed is a process for preparing the same, their use for preparing oil-in-water emulsions by admixture of another oil phase composed of vegetable, animal or synthetic oils and/of fats and/or non-self-emulsifying silicones, and their use in the field of wet currying of leather or pelts.
