Zusammenfassung: | The novel compounds of the general formula I I where A is a radical of a coupling or diazo component which, if necessary after conversion, is capable of complex formation, Ar is an unsubstituted or substituted aromatic or heterocyclic radical, D is a radical of a diazo component and Me is a Co2+, Cu2+, Zn2+, Mn2+ or Ni2+ ion, and the ring B can be further substituted, are very useful for dyeing cellulose fibers, polyesters and blends of cellulose fibers and polyesters. The present dyes are lightfast and fast to washing and to solvents. |
