  <B>Zusatzpatent</B> zum Hauptpatent Nr. 29241.2.    Verfahren     zur        Herstellung        eines        Polyazofarbstoffes.            G=egenstand    des vorliegenden Patentes ist  ein Verfahren zur Herstellung eines     Polyazo-          farbstoffes,    welches darin besteht,     da.ss    man  1     11o1    der     Tetrazoverbindung    aus 3,3'-Di-         methoxy-4,4'-diamino-1,

    kuppelt und den erhaltenen     Polyazofarbstoff     unter Aufspaltung der     Methoxygruppen    mit  einem kupferabgebenden Mittel behandelt.  



  <I>Beispiel:</I>  Die     Tetrazoverbindung    aus 24,4 Teilen       3,3'-Dimethoxy-4,4'-diamino-1,1'-diphenyl    wird    in üblicher Weise     sodaalkalisch    mit 22,4 Tei  len     1-Oxynaphthalin-4-sulfonsäure    zur Zwi  schenverbindung gekuppelt.

   Die isolierte Zwi  schenverbindung trägt man ein in eine Lösung  von 63,2 Teilen der     Kupferkomplexverbin-          dung    des     Monoazofarbstoffes    der Zusammen  setzung

  Die     Kupferkomplexverbindung    des neuen  Farbstoffes stellt getrocknet ein dunkles Pul  ver dar, das sich sowohl in Wasser als auch    in     konzentrierter    Schwefelsäure mit blauer  Farbe löst und Baumwolle in echten blau  grauen Tönen färbt.



  <B> Additional patent </B> to main patent no. 29241.2. Process for the preparation of a polyazo dye. The subject of the present patent is a process for the preparation of a polyazo dye, which consists in that 1 11o1 of the tetrazo compound are obtained from 3,3'-dimethoxy-4,4'-diamino-1,

  1'-diphenyl with 1 mole of 1-oxynaphth.halin-4-sulfonic acid and with 1 mole of the copper complex compound from the monoazo dye of the composition
EMI0001.0019
    couples and treated the polyazo dye obtained with splitting of the methoxy groups with a copper donor.



  <I> Example: </I> The tetrazo compound from 24.4 parts of 3,3'-dimethoxy-4,4'-diamino-1,1'-diphenyl becomes soda-alkaline in the usual way with 22.4 parts of 1-oxynaphthalene -4-sulfonic acid coupled to the inter mediate connection.

   The isolated intermediate compound is incorporated into a solution of 63.2 parts of the copper complex compound of the monoazo dye of the composition
EMI0001.0029
    250 parts of pyridine and 50 parts of 25% ammonia in 500 parts of water. After the coupling has ended, the trisazo dye is isolated and <RTI. By the customary methods

   ID = "0001.0042"> coppered demethylating.



  The copper complex compound of the new dye, when dried, is a dark powder that dissolves in water as well as in concentrated sulfuric acid with a blue color and dyes cotton in real blue-gray tones.
