ABSTRACT:
For coloring in the mass and spin dyeing water-insoluble thermoplastic polymers and polycondensates, especially polyesters, nickel complex disazomethine compounds are used having the general formula (1) ##STR1## in which A and B have the same meaning or are different from each other and each is an isocyclic or heterocyclic residue. The coloring compounds can be added to the polymeric material without previous dispersion. They are dissolved in said material in molecular disperse form so that generally brilliant and clear colorations are obtained. In spin dyeing the filaments substantially retain their high strength and drawing properties; abrasion and clogging of the nozzles or filters do not occur. The colorations are distinguished by a high color strength as well as by high fastnesses to light and to weather and by a good stability in thermofixation.
