Description

  

  Verfahren zur Herstellung eines neuen     metallhaltigen    Farbstoffes.    Es wurde gefunden, dass man einen neuen  metallhaltigen Farbstoff erhält, wenn man  den     Disazofarbstoff    der Formel:  
EMI0001.0003     
    der durch Kuppeln von     diazotierter        Anthra-          nilsäure    in saurem Medium mit     2-Amino-5-          oxynaphthaliri    - 7 -     sulfosäure    und Einwirkung  von     diazotierter        6-Nitro-2-amino-l-phenol-4-          sulfosäure    auf den entstandenen     Monoazofarb-          

  stoff    in alkalischem Medium erhalten werden  kann, mit einem chromabgebenden Mittel  behandelt.  



  Der erhaltene metallhaltige Farbstoff 'stellt  ein dunkel gefärbtes Pulver dar, das sich in  Wasser mit blauer, in konzentrierter Schwe  felsäure mit rotvioletter Farbe löst und Vis  kose in egalen, graublauen Tönen färbt.    <I>Beispiel:</I>  6,8 Teile des Farbstoffes aus     diazotierter          6-Nitro-2-amino-l-phenol-4-sulfosäure    und dem       Monoazofarbstoff,    erhalten durch saure Kupp  lung von     diazotierter        Anthranilsäure    mit 2  Amino-5-oxynaphthalin-7-sulfosäure, werden  in 600 Teilen Wasser gelöst und nach     Züi-          gabe    einer     Fluorchromlösung,    entsprechend  3 Teilen     Cr20s,

      längere Zeit rückfliessend  gekocht. Die Farbe der Lösung geht von  Rot bald nach Blau über. Die Lösung wird  nötigenfalls filtriert und der Farbstoff durch  Eindampfen der Lösung gewonnen.



  Process for the production of a new metal-containing dye. It has been found that a new metal-containing dye is obtained by using the disazo dye of the formula:
EMI0001.0003
    by coupling diazotized anthranilic acid in acidic medium with 2-amino-5-oxynaphthaliri - 7 - sulfonic acid and the action of diazotized 6-nitro-2-amino-1-phenol-4-sulfonic acid on the resulting monoazo

  substance can be obtained in an alkaline medium, treated with a chromium donating agent.



  The metal-containing dye obtained is a dark-colored powder which dissolves in water with blue, in concentrated sulfuric acid with a red-violet color and colors viscose in level, gray-blue tones. <I> Example: </I> 6.8 parts of the dye from diazotized 6-nitro-2-amino-1-phenol-4-sulfonic acid and the monoazo dye, obtained by acid coupling of diazotized anthranilic acid with 2 amino-5- oxynaphthalene-7-sulfonic acid, are dissolved in 600 parts of water and, after adding a fluorochrome solution, corresponding to 3 parts of Cr20s,

      Boiled back for a long time. The color of the solution soon changes from red to blue. If necessary, the solution is filtered and the dye is obtained by evaporating the solution.
