Abstract: Pigment preparations useful for pigmenting or delustering finishes for leather and leather substitutes consist essentially of pigments or delusterants or a mixture thereof, binders, water and if desired further customary dispersants and auxiliaries, the binders used being copolymers of A) from 40 to 80% by weight of at least one aromatic vinyl compound of the general formula I (* CHEMICAL STRUCTURE *) I where R1, R2 and R3 are each hydrogen, methyl or ethyl and n is 1 or 2, B) from 20 to 60% by weight of acrylic acid or methacrylic acid or a mixture thereof, and C) from 0 to 10% by weight of further copolymerizable monomers, in the form of their salts.

Abstract: A process for dressing leather by layerwise application to the leather of 2 to 6 coats of an aq. compsn. comprising (by wt., as solids) 2-15% of one or more polymeric binders, 2-10% casein, 2-15% of a crosslinking agent and a remainder to 100% water, to give a total amt. of 10-100g solids/m2 of the leather surface, drying at 20-80 deg.C and fixing the finish by a 1- to 3 times heat treatment at 150-220 deg.C with a total contact time of 0.1-5 sec.
