摘要

aqueous formulation, copolymer, process for the preparation of copolymers, and use of copolymers and aqueous formulations. The invention relates to a process for the production of leather, characterized in that hides, stripped skins or semi-finished products are treated with at least one copolymer (a), which is obtained by copolymerizing the following comonomers: (a) by at least one ethylenically unsaturated c3-c10-carboxylic acid or at least one ethylenically unsaturated c4-c10-dicarboxylic acid or anhydride thereof, (b) at least one (meth) acrylate of a branched c3-c10-alkanol, (c ) at least one (meth) acrylate of a primary c 4 -C 20 alkanol.
