ABSTRACT:
A mixed metal complex compound that contains for every atom of a trivalent metal one molecule of an azo or azomethine compound which contains a complex-forming group in the ortho, ortho'-positions to the azo or azomethine bridge, and one molecule of an azo or azomethine compound acting as trifunctional ligand which contains a complex-forming group in the ortho-position to the azo or azomethine bridge and contains two non-ionisable co-ordination positions. These mixed metal complexes dye nitrogenous fibers such as wool in level shades which are stable to acids and alkalis and have good fastness to light, rubbing, perspiration and water.
