Formulations containing pigments and/or delustrants, a solution of a pigment binder and, if appropriate, additives, characterized in that the pigment binder is a copolymer of, relative to the weight of the copolymer, 10-40% by weight of an acrylic acid ester having 1-12 C atoms in the alcohol chain, 10-40% by weight of a methacrylic acid ester having 1-4 C atoms in the alcohol chain, 10-30% by weight of N-vinylpyrrolidone, 5-15% by weight of acrylic acid and 10-20% by weight of a vinyl ester having 1-4 C atoms in the acid chain, which have been prepared in an organic solvent which is miscible with water in the presence of a regulator and of a per-compound or an azo compound which donates free radicals at the polymerization temperature, and the use of these formulations for pigmenting and/or delustring dressing agents for leather and leather imitations. |
