Abstract

The present invention relates to the use of metal complex compounds with terpyridine ligands as oxidation catalysts. The present invention relates also to formulations comprising such metal complex compounds, to novel metal complex compounds, and to novel ligands. The metal complex compounds are used especially tor improving the action of peroxides, for example in the treatment of textile material, without at the same time causing any appreciable damage to fibres and dyeings.
