USE OF BLEACHING CATALYST COMBINATIONS AND BLEACHING AGENT COMPOSITIONS CONTAINING THEM

摘要

The invention relates to the use of bleaching catalyst combinations containing a transition metal complex (i) and an imine compound (ii) in order to enhance the action of peroxy compounds. The combination according to the invention contains (i) an Mn, Fe, Co or Cu complex with a ligand of the general Formula (1) and (ii) an iminium salt, oxaziridinium salt, sulfanimine or sulfonimine. A preferred combination contains 1,3,3-tris(2-pyridyl)-3H-imidazole[1,5-a]pyridiyl-4-ium tetrachlorocobaltate and cobalt-bis[di(2-pyridyl)ketone hydrate].
