An aqueous dispersion of a copolymer having an average molecular weight of between 2,000 and 100,000, and formed between more than 10% by weight and less than 50% by weight of a monomer of acrylic acid or methacrylic acid and between more than 50% in weight and less than 90% by weight of at least one of the following hydrophobic monomers: C10-22 alkyl (meth) acrylates, C8-22 alkoxy- or C6-12 alkyl phenoxypoly (ethylene oxide) (meth) acrylates, C12 -22 primary alkanes, and vinyl esters of C12-22 alkyl carboxylic acids useful in a leather treatment process. |
