Abstract
The present invention relates to inhibiting dye transfer compositions comprising PA0 a) a polymer selected from polyamine N-oxide containing polymers which contain units having the following structure formula: ##STR1## wherein P is a polymerizable unit, whereto the N--O group can be attached to or wherein the N--O group forms part of the polymerizable unit or a combination of both. PA1 A is ##STR2## X is or 0 or 1; 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. PA0 b) a builder.
