CA 2490095

Transition metal complexes are used as bleaching catalysts for peroxy compounds. Transition metal complexes to be used according to the invention contain a ligand of the general formula (I) wherein B is a bridge member, such as o-phenylene or pyridine-2,6-diyl, and A represents the group -NH-CO-R1 or formula (II).

La présente invention concerne des complexes de métaux de transition utilisés comme catalyseurs de blanchiment pour des composés peroxy. Les complexes de métaux de transitions selon l'invention contiennent un ligand représenté par la formule générale (I) dans laquelle B est un pont et notamment un o-phénylène ou un pyridine-2,6-diyle, A étant le groupe -NH-CO-R¿1? ou étant représenté par la formule (II).
