ABSTRACT:
New metal-complex disazomethine compounds of the formulae ##STR1## WHEREIN R is a single bond, a straight-chained or branched alkylene radical which may be interrupted by one or more hetero atoms, such as 1, 2, 3 or 4 moieties selected from a group consisting of isocyclic and heterocyclic ring and other bivalent group, or is a cycloalkylene radical, an arylene or a heterocyclic radical, Z is a group capable of forming metal complexes, X is a carboxylic acid group, carboxylic acid ester group, an optionally substituted carboxylic acid amide or carboxylic acid hydrazide group and M is a bivalent metal atom, had been found which are very well suitable as colorants, especially as pigments, for example, for coloring plastic masses, paints, lacquers, for the use in spin-dyeing of viscose and cellulose acetate, for coloring printing pastes in graphic industry and paper masses, and have a high tinctorial strength, a good transparency, pure shades, excellent fastness to migration, to overvarnishing to light, to weather, to solvents and to heat, corresponding to the material colored with them.
