schwarzer walk- und lichtechter Wollfarbstoffe durch die Vereinigung diazotierter 5-Nitro- -2-aminophenoläther mit Aryl-2.8-aminouaphtol-6-sulfosäure in saurer Lösung.
Es hat sich nnn herausgestellt, dass man zu Farbstoffen mit ganz ähnlichen Eigenschaften gelangt, wenn man die 5-Nitroaminophenyläther durch andere unsulfierte Nitroamino-

Beispiel 10 138 Teile o-Nitranilin werden wie üblich diazotiert. Die überschüssige Säure wird

Ersetzt man das o-Nitranilin durch ein Derivat, wie 2-Nitro-4-acetphenylendiamin und die Phonyl-2. 8-aminonaphtol-6-sulfosiiure durch die Tolyl- oder Anisidyl-2 8.6-Aminonaphtolsnlfosäure etc., se bleiben die Eigenschaften im wesentlichen dieselben.

Process for the preparation of monoazo dyes for wool.
EMI1.1
black milled and lightfast wool dyes by combining diazotized 5-nitro- -2-aminophenol ethers with aryl-2.8-aminouaphthol-6-sulfonic acid in acidic solution.
It has now been found that dyes with very similar properties are obtained if the 5-nitroaminophenyl ethers are replaced by other unsulfated nitroamino-

Example 10 138 parts of o-nitroaniline are diazotized as usual. The excess acid will

If the o-nitroaniline is replaced by a derivative such as 2-nitro-4-acetphenylenediamine and the phonyl-2. 8-aminonaphthol-6-sulfonic acid by tolyl- or anisidyl-2,6-aminonaphthol-sulfonic acid, etc., the properties remain essentially the same.
