The present invention relates to dye transfer inhibiting compositions comprising: a) a polymer selected from polyamine N-oxide containing polymers which contain units having the structure formula (1) 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 0 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 form part of these groups; b) a bleaching agent.

La présente invention concerne des compositions inhibant le transfert de teintures, comprenant: a) un polymère choisi parmi des polymères contenant des oxydes azotés de polyamine et qui contiennent des unités de formule (I) dans laquelle P représente un motif polymérisable, le groupe N-O pouvant être fixé à ladite unité, constituer une partie de ladite unité, ou bien à la fois constituer une partie de cette unité et y être fixé; A représente (a), (b), (c), -O-, -S-, (d); x vaut 0 ou 1; R représente des groupes aliphatiques, aliphatiques éthoxylés, aromatiques, hétérocycliques, ou alicycliques, ou bien une combinaison de ceux-ci, l'azote du group N-O pouvant être fixé à ceux-ci ou pouvant constituer une partie de ceux-ci; et b) un agent de blanchiment.
