Use of transition metal complexes having oxime ligands as bleach catalysts

The present invention relates to the use of certain transition metal complexes for increasing the bleaching action of peroxygen compounds during the bleaching of colored soilings both on textiles and also on hard surfaces, and to laundry detergents and cleaners which comprise complex compounds of this type. Transition metal complexes used as bleach catalysts of the formula (1)whereM is a metal atom from the group Mn, Fe, Co, Ni, Mo, W,L is a ligand of the formulaRis C-C-alkyl, C-C-alkenyl or C-C-aryl,Ris H, C-C-alkyl, C-C-alkenyl, C-C-aryl or where z=0 or 1,X is a neutral or anion ligand from the group consisting of pyridines, imidazolines, methylimidazoles, picolines, lutidines, chloride, bromide, nitrate, perchlorate, citrate, hexafluorophosphate or anions of organic acids having C-Ccarbon atoms, n is a number from 2 to 4 and m is a number from 0 to 4.
