The present invention relates to the the use of water-soluble copolymers based on acrylamidoalkylenesulfonic acid, vinylacetamide and, if appropriate, other monomers, comprising

Use of a water-soluble copolymers based on acrylamidoalkylenesulfonic

Use of copolymers based on vinyl monomers and carboxylic acid amides as a detergent additive The present invention relates to the use of copolymers comprising 75-95% by weight of the total amount of the monomer of at least one vinyl monomer which is free from carboxyl and amide groups, 5-20% by weight of at least one carboxylic acid amide of the formula (I) ##STR1## in which R is a hydrogen atom or a methylol radical, R.sup.1 is a hydrogen atom or a C.sub.1 -C.sub.3 -alkyl radical and R.sup.2 is a hydrogen atom or a methyl radical and if appropriate together with not more than 5% by weight of a copolymerizable unsaturated carboxylic acid, as a detergent additive for preventing the reabsorption of detached dyestuffs and dyestuff degradation products.

Use of copolymers based on vinyl monomers and carboxylic acid amides as
