ABSTRACT:
1:1 metal complexes of bis-azomethines of the formula ##STR1## wherein R denotes an alkylene radical which contains 2-8 C atoms and is optionally interrupted by hetero-atoms, X denotes a H or halogen atom or an alkyl, alkoxy, carboxyl, alkoxy-carbonyl or phenylazo group and Y and Z denote H or halogen atoms, or wherein the substituents Y and Z form a fused benzene ring, if R contains a hetero-atom, Y and Z must not be H atoms, and if R contains 2 C atoms, X, Y and Z must not be H atoms, and a metal are valuable pigments coloring plastics and printing inks in fast yellow to range shades.
