USE OF TRANSITION METAL COMPLEXES WITH NITROGEN-CONTAINING POLYDENTATE LIGANDS AS A BLEACHING CATALYST AND BLEACHING AGENT COMPOSITION

摘要

Transition metal complexes are used as a bleaching catalyst for peroxy compounds. Transition metal complexes to be used according to the invention contain a polydentate ligand of the general formula (I), wherein B preferabl y denotes a heterocyclic or heteroaromatic member of the formula (II), in particular pyridine-2,6-diyl, R1-C=N-R4 and R2-C=N-R4 represent a heterocycl ic or heteroaromatic ring or R3 and/or R4 represent a heteroaryl, aryl or heteroarylmethyl radical.
