USE OF COPOLYMERS BASED ON VINYL MONOMERS AND CARBOXYLIC ACID AMIDES AS A DETERGENT ADDITIVE

摘要

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) <IMG> in which R is a hydrogen atom or a methylol radical, R1 is a hydrogen atom or a C1-C3-alkyl radical and R2 is a hydrogen atom or a methyl radical and if appropriate together with not more than 5% by weight of a copolymorizable unsaturated carboxylic acid, as a detergent additive for preventing the reabsorption of detached dyestuffs and dyestuff degradation products.
