ABSTRACT:
New valuable metal complex disazomethine compounds of the formula ##STR1## had been found wherein R is hydrogen, an alkyl, aralkyl, cycloalkyl, aryl or heterocyclic radical, an amino group which may be substituted by alkyl or aryl radicals, or a guanidino group, X stands for a -CO- or -SO.sub.2 -group, Y stands for hydrogen, a halogen atom, an alkyl, alkoxy or nitro group, R.sub.1 stands for hydrogen or an alkyl radical, Z stands for hydrogen, a halogen atom, an alkoxy or nitro group and M is a bivalent metal atom.
The new compounds are very well suitable as dyes, especially good pigments, and can be used, for example for the dyeing of masses of synthetic materials, for pigmenting paints and lacquers, for spin-dyeing viscose and cellulose acetate and for pigmenting polyethylene or similar polymers, caoutchouc or synthetic leather.
Their dyeings have excellent fastnesses as, for example, to migration, light, weather and solvents.
Furthermore, the compounds themselves have an excellent heat stability, a high color intensity and high degree of purity of the shades.
