    <I>Beispiel:

  </I>  Die     Tetrazoverbindung    aus 22,7 Teilen     1-          Amino-4-(4'-a.minobenzoy1)-aminobenzol    wird  in     üblielier    Weise zuerst in     sodaalkalischer    Lö  sung mit 13,8 Teilen     1-Oxybenzol-2-earbon-          säure    und anschliessend in essigsaurer Lö  sung mit 13,7 Teilen     1-Amino-2-methoxy-5-          methylbenzol    gekuppelt.

   Die Zwischenver  bindung wird     diazotiert    und die     Diazo-disazo-          v        erbindung    in 50     %        iger    wässriger     Pyridin-          lösung    mit der in üblicher Weise hergestellten       Kupferkomplexverbindung    aus 46,8 Teilen  des     Monoazofarbstoffes    der Zusammensetzung

    gekuppelt. Der gebildete     Tetrakisazofarbstoff     wird vom     Pyridin    getrennt und durch Um  lösen gereinigt.  



  Er ist ein dunkles Pulver, das sich in Was  ser mit oliver und in konzentrierter Schwefel  säure mit rotbrauner Farbe löst. Er färbt  Baumwolle und Fasern aus regenerierter       Cellulose    in schönen     gelbstichigen        Khakitönen,     deren     Echtheiten    durch Nachbehandeln mit  Salzen des zweiwertigen Kupfers, besonders  in Gegenwart von     Imino-    oder     Aminogruppen     enthaltenden     polymeren    Substanzen, wie sie  z.

      Additional patent to main patent No. 284077. Process for the production of a polyazo dye. The present patent relates to a process for the preparation of a polyazo dye, which is characterized in that the tetrazotization of 1 mole of 1-amino-4- (4'-aminobenzoyl)

  -aminobenzene and coupling with 1 mole of 1-oxybenzene-2-carboxylic acid, the intermediate compound obtainable with 1 mole of 1-amino-2-methoxy-5-methylbenzene couples, the intermediate compound obtained diazotizes and the diazo-disazo compound with 1 mole of the copper complex compound of the monoazo dye the composition
EMI0001.0021
    <I> example:

  The tetrazo compound from 22.7 parts of 1- amino-4- (4'-a.minobenzoy1) -aminobenzene is first used in the usual manner in a soda-alkaline solution with 13.8 parts of 1-oxybenzene-2-earbonic acid and then coupled in acetic acid solution with 13.7 parts of 1-amino-2-methoxy-5-methylbenzene.

   The intermediate compound is diazotized and the diazo-disazo compound in 50% aqueous pyridine solution with the conventionally prepared copper complex compound from 46.8 parts of the monoazo dye of the composition
EMI0001.0041
    coupled. The tetrakisazo dye formed is separated from the pyridine and purified by dissolving.



  It is a dark powder that dissolves in water with an olive color and in concentrated sulfuric acid with a red-brown color. It dyes cotton and fibers made from regenerated cellulose in beautiful yellowish khaki tones, whose fastness properties are obtained by aftertreatment with salts of divalent copper, especially in the presence of imino or amino group-containing polymeric substances, such as those found for. B. in the Swiss patents Num numbers 253709, 261048, 263481 and 263482 be written are to be improved.
