The present invention relates to a bleaching composition comprising: a) a monomer ligand or transition metal catalyst thereof of a ligand having the formula (I); wherein each R is independently hydrogen, F, Cl, Br, hydroxyl, C1- C4-alkylO-, -NH-CO-H, -NH-CO-C1-C4-alkyl, -NH2, -NH-C1-C4-alkyl, and C1-C4- alkyl; R1 and R2 are independently selected from: C1-C4-alkyl, C6-C10-aryl, and, a group containing a heteroatom capable of coordinating to a transition metal, wherein at least one of R1 and R2 is the group containing the heteroatom; R3 and R4 are independently selected from hydrogen, C1-C8 alkyl, C1-C8-alkyl-O-C1-C8-alkyl, C1-C8-alkyl-O-C6-C10-aryl, C6-C10-aryl, C1-C8- hydroxyalkyl, and -(CH2)nC(O)OR5 wherein R5 is independently selected from: hydrogen, C1-C4-alkyl, n is from 0 to 4, and mixtures thereof; and , X is selected from C=O, -[C(R6)2]y- wherein Y is from 0 to 3, each R6 is independently selected from hydrogen, hydroxyl, C1-C4-alkoxy, C1-C4-alkyl; and b) the balance carriers and adjunct ingredient.

La présente invention concerne une composition de blanchiment comprenant : a) un ligand monomère ou un catalyseur métallique de transition d'un ligand de formule (I) : dans laquelle chaque R est indépendamment hydrogène, F, CI, Br, hydroxyle, C1-C4-alkyleO-, -NH-CO-H, -NH-CO-alkyle C1-C4, -NH2, -NH-alkyle C1-C4 et alkyle C1-C4 ; R1 et R2 étant indépendamment sélectionnés entre : alkyle C1-C4, aryle C6-C10, et, un groupe contenant un hétéroatome pouvant se coordonner à un métal de transition, dans lequel au moins un élément entre R1 et R2 représente le groupe contenant l'hétéroatome ; R3 et R4 étant indépendamment sélectionnés entre hydrogène, alkyle C1-C8, alkyle C1-C8-alkyle O-C1-C8, alkyle C1-C8-O-aryle C6-C10, aryle C6-C10, hydroxyalkyle C1-C8, et (CH2)¿n?C(O)OR5, R5 étant indépendamment sélectionnés entre : hydrogène, alkyle C1-C4, n représente 0 à 4, et des mélanges desdits éléments ; et, X étant sélectionné entre C=O, -[C(R6)2]¿y?- où Y représente 0 à 3, chaque R6 étant indépendamment sélectionné entre hydrogène, hydroxyle, alcoxy C1-C4, alkyle C1-C4 ; et b) le solde étant constitué par des supports et des ingrédients d'adjonction.
