CA 2140289

The present invention relates to inhibiting dye transfer compositions comprising polyamine N-oxide 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 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 forms part of these groups.

Les compositions décrites comprennent des polymères de polyamine N-oxyde contenant des unités de la formule (I), où P représente une unité polymérisable, à laquelle le groupe N-O peut être lié, et/ou dans laquelle le groupe N-O fait partie de l'unité polymérisable. A représente (a), (b), (c); -O-, -S-, (d); x vaut O ou 1; R représente des groupes aliphatiques, des groupes aliphatiques éthoxylés, aromatiques, hétérocycliques ou alicycliques ou toute combinaison de ceux-ci, auxquels l'azote du groupe N-O peut être lié ou dans lesquels l'azote du groupe N-O fait partie de ces groupes.
