  Verfahren zur Darstellung eines     Polyazofarbstoffes.       Es wurde gefunden, dass man zu einem  wertvollen grünen     Direktfarbstoff    gelangt,  wenn man die dianotierte     Aminoazoverbin-          dung        aus    dianotierter     4-Amirroacetariilid-3-          sulfosäure    und     1-Amir)o-2-oxyriaphtalin-ox-          iith3-läther@schwefelsäureester    mit dem Konden  sationsprodukt aus     molaren    Mengen     Cyanur-          phlorid,

          1-Äthylamino-8-oxynaphtalin-3.6-          disulfosärrre,    4-Arnino-4'-oxyazobenzol-2.3'-         dicarbonsäure    und     4-Methyl-l-thiopherrol    kup  pelt.  



  <I>Beispiel</I>  Die in bekannter     Weise    hergestellte     Diazo-          verbindung    aus 524 Gewichtsteilen des     Azo-          farbstoffes    aus     4-Aminoacetanilid-3-sulfosäure     und     1-Amino    - 2 -     oxynaphtalin    -     oxäthylschwe-          felsäureester    von der Formel:

    
EMI0001.0027     
    wird mit Eiswasser     verpastet    und zu der  zweckmässig mit     Pyridin    versetzten Lösung  des Kondensationsproduktes aus     molaren    Men  gen     Cyanurchlorid,        1-Äthylamino-8-oxynaph-          talicr-3.6-disulfosiiure,        4-Amirro-4'-oxyazoben-          zol-2.        3'-dicarbonsäure    und     4-Methyl-l-thiophe-          nol    bei 5-10   gegeben.

      Der wie üblich aufgearbeitete Farbstoff  stellt in trockenem Zustand ein dunkles bronze  glänzendes Pulver dar, das sich mit grüner  Farbe in Wasser löst und aus-dem Glaubersalz  Sodabad in leuchtend grünen Tönen von sehr  guter Lichtechtheit auf die pflanzliche Faser  zieht.



  Process for the preparation of a polyazo dye. It has been found that a valuable green direct dye is obtained if the dianotated aminoazo compound of dianotated 4-amirroacetariilide-3-sulfonic acid and 1-amir) o-2-oxyriaphtalin-oxyith3-ether @ sulfuric acid ester is used with the condensate cation product of molar amounts of cyanuric chloride,

          1-Ethylamino-8-oxynaphthalene-3.6-disulfosärrre, 4-amino-4'-oxyazobenzene-2.3'-dicarboxylic acid and 4-methyl-1-thiopherrole kup pelt.



  <I> Example </I> The diazo compound prepared in a known manner from 524 parts by weight of the azo dye from 4-aminoacetanilide-3-sulfonic acid and 1-amino-2-oxynaphthalene-oxethylsulfuric acid ester of the formula:

    
EMI0001.0027
    is pasted with ice water and added to the solution of the condensation product of molar amounts of cyanuric chloride, 1-ethylamino-8-oxynaphthalicr-3,6-disulfonic acid, 4-amirro-4'-oxyazoben-zol-2. 3'-dicarboxylic acid and 4-methyl-1-thiophenol added at 5-10.

      The dye, processed as usual, is a dark, shiny bronze powder when dry, which dissolves in water with a green color and draws from the Glauber's salt soda bath in bright green shades of very good lightfastness onto the vegetable fiber.
