  Verfahren zur Herstellung eines     Polyazofarbstoffes.       Es wurde gefunden, dass man einen  neuen     Polyazofarbstoff    erhalten kann, wenn  man auf 2     Mol        Cyanurchlorid    2     Mol    des       Monoazofarbstoffes    aus     diazotierter    2 -     (4'-          Aminobenzoylamino)    -     naplhthalin    - 4,8 -     disul-          fonsäure    und     1-Methyl-3-aminobenzol,

      2     Mol          4-Amino-4'-oxyazobenzol-3'-carbonsäure    und  1     Mol        1,4-Diaminobenzol    derart einwirken  lässt, dass je ein     Mol        Cyanurchlorid    mit den       Aminogruppen    von einem     Mol    des     Monoa.zo-          farbstoffes    aus     diazotierter    2- (4'-     Amino-          benzoylamino)    -     naphthalin-    4,

   8 - dis     ulfonsäure     und     1-Methyl-3-aminobenzol    und von einem       Mol        4-Amino-4'-oxyazobenzol-3'-carbonsäure     und beide     Mol        Cyanurchlorid    mit je einer       Aminogruppe    von 1     Mol        1,4-Diaminobenzol     reagieren. Der neue     Polyazofarbstoff    färbt  Baumwolle in schwach     alkalischem    Badebei  Gegenwart von Kupfersulfat und     weinsaurem     Natrium in waschechtem gelbem Tone an.

    <I>Beispiel:</I>  54 Gewichtsteile des     Monoazofarbstoffes     aus     diazotierter    2-(4'-Aminobenzoylamino)-         naphthalin-4,8-disulfonsäure    und     1-Methyl-3-          aminobenzol        werden    in neutraler     wässeriger     Lösung zu einer kalten wässerigen     An-          schlämmung    von 18,4     Gewichtsteilen        Cyanur-          chlorid    gegeben.

   Die dabei     entstehende    Salz  säure wird durch die entsprechende Menge       Natriumcarbonat        neutralisiert.    Hernach wer  den 5,4 Gewichtsteile     1,4-Diaminobenzol,    die  in Wasser :gelöst wurden, zugefügt und die  Temperatur auf 40   erhöht. Nach 2 Stunden  gibt man 27,8 Gewichtsteile     4-amino-4'-oxy-          azo.benzol-3'-carbonsaures        Natrium    zu und  hält die     Temperatur    während der gleichen  Zeit auf<B>80'.</B> Das     ditertiäre    Kondensations  produkt ist nach dieser Zeit gebildet.

   Es wird  mittels     Kochsalz        abgeschieden        und    getrock  net.



  Process for the preparation of a polyazo dye. It has been found that a new polyazo dye can be obtained if, per 2 moles of cyanuric chloride, 2 moles of the monoazo dye from diazotized 2- (4'-aminobenzoylamino) -naphthalene-4,8-disulfonic acid and 1-methyl-3-aminobenzene ,

      Allow 2 moles of 4-amino-4'-oxyazobenzene-3'-carboxylic acid and 1 mole of 1,4-diaminobenzene to act in such a way that one mole of cyanuric chloride with the amino groups of one mole of the monoazobenzene dye from diazotized 2- (4 '- Amino benzoylamino) - naphthalene- 4,

   8 - disulfonic acid and 1-methyl-3-aminobenzene and one mole of 4-amino-4'-oxyazobenzene-3'-carboxylic acid and both moles of cyanuric chloride each react with an amino group of 1 mole of 1,4-diaminobenzene. The new polyazo dye stains cotton in a weakly alkaline bath in the presence of copper sulfate and tartrate of sodium in a washable yellow shade.

    <I> Example: </I> 54 parts by weight of the monoazo dye from diazotized 2- (4'-aminobenzoylamino) - naphthalene-4,8-disulfonic acid and 1-methyl-3-aminobenzene are in neutral aqueous solution to form a cold aqueous mixture given suspension of 18.4 parts by weight of cyanuric chloride.

   The resulting hydrochloric acid is neutralized with the appropriate amount of sodium carbonate. Thereafter who the 5.4 parts by weight of 1,4-diaminobenzene, which were dissolved in water: added and the temperature increased to 40. After 2 hours, 27.8 parts by weight of 4-amino-4'-oxy-azo.benzene-3'-carboxylic acid sodium are added and the temperature is maintained at <B> 80 'for the same time. </B> The ditertiary condensation product is formed after this time.

   It is deposited using table salt and net getrock.
