Description

  

      Zusatzpatent    zum Hauptpatent Nr. 145448.    Verfahren zur Herstellung eines neuen metallhaltigen     Farbstoffes.       Es wurde gefunden, dass man einen neuen  metallhaltigen Farbstoff erhält, wenn man  den     Disazofarbstoff    der Formel:  
EMI0001.0004     
    der durch Kuppeln von dianotierter     Anthra-          nilsäure    in saurem Medium mit     2-Arnino-5-          oxynaphtalin-7-sulfosäure    und Einwirkung von  dianotiertem     4-Chlor-5-nitro-2-amino-l-phenol     auf den entstandenen     Monoazofarbstoff    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 violetter Farbe löst und Viskose    in egalen, kräftig     grünstichiggrauen    Tönen  färbt.

      <I>Beispiel:</I>    6,1 Teile des     Disazofarbstoffes,    erhalten  durch alkalische Kupplung von dianotiertem  4 -Chlor- 5 -     nitro    -2-     amirro    -1- Phenol mit dem  durch saure Kupplung aus dianotierter An  thranilsäure und     2-Amino-5-oxynaphthalin-7-          sulfosäure    erhältlichen     Monoazofarbstoff,    wer  den in 600 Teilen heissem Wasser gelöst und  nach Zugabe von 11,2 Teilen kristallisiertem       Natriumacetat    und einer     Fluorchromlösung,     entsprechend 3 Teilen     Crz0s,    längere Zeit  rückfliessend gekocht.

   Nach beendeter     Chro-          mierung    wird die blaue     Farbstofflösung    fil  triert und zur Trockne eingedampft.



      Additional patent to main patent no. 145448. 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:
EMI0001.0004
    obtained by coupling dianotized anthranilic acid in an acidic medium with 2-amino-5-oxynaphthalene-7-sulfonic acid and the action of dianotated 4-chloro-5-nitro-2-amino-1-phenol on the resulting monoazo dye in an alkaline medium can be treated with a chromium-releasing agent.



  The metal-containing dye obtained is a dark-colored powder that turns blue in water, in concentrated sulfur. Dissolves rock acid with a violet color and dyes viscose in level, strong greenish gray tones.

      <I> Example: </I> 6.1 parts of the disazo dye, obtained by alkaline coupling of dianotated 4-chloro-5-nitro -2-amirro-1-phenol with the acidic coupling of dianotated anthranilic acid and 2-amino -5-oxynaphthalene-7-sulfonic acid available monoazo dye, who dissolved in 600 parts of hot water and refluxed for a long time after the addition of 11.2 parts of crystallized sodium acetate and a fluorochrome solution, corresponding to 3 parts of Crz0s.

   When the chroming has ended, the blue dye solution is filtered and evaporated to dryness.
