Description

  

      Yerfaliren    zur Herstellung     eines    neuen     Farbstoffes.       Es wurde gefunden, dass man einen neuen  Farbstoff erhält, wenn man     diazotierte        5-          Nitro-2-amino-l-phenol-4-sulfosäure    mit 3  Aminonaphthalin-1,8-dikarbonsäure     vereinigt.     Der neue Farbstoff bildet ein braunschwar  zes Pulver, das sich in Wasser mit violett  roter, in Schwefelsäure mit gelbbrauner  Farbe löst. Er färbt Wolle aus saurem Bade  in roten Tönen, welche beim     Nachchromie-          ren        nach        gelbgrün    umschlagen.

   Im Chrom  druck auf Baumwolle erzeugt er gelbgrüne  Töne.  



       Beispiel:     10,7 Teile     3-Aminonaphthalin-1,8-dikar-          bonsäureanhydrid    werden mit Hilfe von 10  Teilen 30     %iger        Nationlauge    in 150 Teilen  Wasser heiss gelöst, mit 10 Teilen Soda. ver  setzt, abgekühlt und mit der aus 11,7 Tei  len     5-Nitro-2-amino-l-phenol-4-sulfosäure    her-    gestellten     Diazaverbindung    versetzt. Nach  erfolgter Kupplung wird der Farbstoff aus  gesalzen, filtriert und getrocknet.



      Yerfaliren to make a new dye. It has been found that a new dye is obtained when diazotized 5-nitro-2-amino-1-phenol-4-sulfonic acid is combined with 3-aminonaphthalene-1,8-dicarboxylic acid. The new dye forms a brownish-black powder that dissolves in water with a violet-red color and in sulfuric acid with a yellow-brown color. He dyes wool from an acid bath in red tones, which turn to yellow-green when chromium-plating.

   In the chrome print on cotton, it creates yellow-green tones.



       Example: 10.7 parts of 3-aminonaphthalene-1,8-dicarboxylic acid anhydride are dissolved in 150 parts of hot water with 10 parts of 30% strength sodium hydroxide solution, with 10 parts of soda. offset, cooled and mixed with the diaza compound prepared from 11.7 parts of 5-nitro-2-amino-1-phenol-4-sulfonic acid. After coupling, the dye is salted out, filtered and dried.

PATENTANSPRUCH: Verfahren zur Herstellung eines neuen Farbstoffes, dadurch gekennzeichnet, dass man diazotierte 5-Nitro-2-amino-l-phenol-4- sulfosäure mit 3-Aminonaphthalin-1,8-dikar- bonsäure vereinigt. Der neue Farbstoff bil det ein braunschwarzes Pulver, das sich in Wasser mit violettroter, in Schwefelsäure mit gelbbrauner Farbe löst. PATENT CLAIM: A process for the production of a new dye, characterized in that diazotized 5-nitro-2-amino-1-phenol-4-sulfonic acid is combined with 3-aminonaphthalene-1,8-dicarboxylic acid. The new dye forms a brownish-black powder that dissolves in water with a violet-red color and in sulfuric acid with a yellow-brown color. Er färbt Wolle aus saurem Bade in roten Tönen, welche beim Nachchromieren nach gelbgrün um schlagen. Im Chromdruck auf Baumwolle erzeugt er gelbgrüne Töne. It dyes wool from acid baths in red tones, which turn to yellow-green when they are chromed. In the chrome print on cotton it creates yellow-green tones.
