Abstract

The present invention relates to inhibiting dye transfer compositions comprising polyamine N-oxide polymers which contain units having the following structure formula: ##STR1## wherein P is a polymerizable unit, whereto the N--group can be attached to or wherein the N--O group forms part of the polymerizable unit or a combination of both. ##STR2## R are aliphatic, ethoxylated aliphatics, aromatic, heterocyclic or alicyclic groups or any combination thereof whereto the nitrogen of the N--O group can be attached or wherein the nitrogen of the N--O group form part of these groups.
