    Abstract: Finely powdered, water-insoluble, cross-linked polymers contain polymerised units of 1-vinyl pyrrolidone and/or 1-vinyl imidazoles having the formula (I), in which R, R1 and R2 are different or the same and stand for H, C1-C4 alkyl or phenyl, or polymerised units of 4-vinyl pyridin-N-oxide. At least 90 % by weight of these polymers have a particle size from 0.1 to 500 .mu.m. These polymers are useful as additives for washing and cleaning agents to prevent colours from migrating during washing. Also disclosed are washing and cleaning agents based on surfactants and if required builders and other usual components, said washing and cleaning agents containing from 0.1 to 10 % by weight of the disclosed water-insoluble, cross-linked polymers.
