Abstract: The use of water-soluble copolymers which contain (a) 5 to 20 mol % N-vinyl imidazole or 4-vinyl pyridine-N-oxide, (b) 95 to 50 mol % N-vinyl pyrrolidone, N-vinyl oxazolidone, methyl-N-vinyl imidazole or their mixtures and (c) 0 to 30 mol % of other monoethylenically unsaturated monomers, incorporated by polymerization, and have a mean molar mass Mw of over 50,000, as colour transfer inhibitors in detergents.

Abstract: Washing agents based on surfactants, organic co-builders and polymeric dye transfer inhibitors, in which (a) the organic co-builder is a polymeric polycarboxylate with a Mw of up to 25,000 and (b) the dye transfer inhibitor is a water-soluble polymeric dye transfer inhibitor with a Mw of at least 30,000 and/or a water-insoluble crosslinked polymeric dye transfer inhibitor with a particle size of 0.1 - 500 mu m.
