Abstract
The present invention relates to dye transfer inhibiting compositions comprising: a) a polymer selected from polyamine N-oxide containing polymers which contain units having structure formula (I), wherein P is a polymerisable unit, whereto the N--O group can be attached to or wherein the N--O group forms part of the polymerisable unit or a combination of both; A is (a), (b), (c), --O--, --S--, (d); x is O or 1; R are aliphatic, ethoxylated aliphatic, 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 forms part of these groups; b) a polymeric dispersing agent.
Claims9
