  <B>Zusatzpatent</B> zum     Hauptpatent    Nr. 245067.    Verfahren zur Herstellung eines Substantiven     Azofarbstoffes.       Gegenstand des vorliegenden Zusatz  patentes ist ein Verfahren zur     Herstellung     eines Substantiven     Azofarbstoffes,    dadurch  gekennzeichnet, dass man 1     Mol        dia.zotiertes          1-Oxy-2-aminobenzol    - 4 -     carbonsäure-phenyl-          amid    mit 1     Mol    des sekundären Kondensa  tionsproduktes aus 1     Mol        Cyanurchlorid,

       1     Mol        2-Amino-5-oxynaphthalin    - 7 -     sulfon-          säure    und 1     Mol        4-Amino-4'-oxy-1,1'-azo-          benzol-3'-carbonsäure    in alkalischem Medium  vereinigt.  



  Der neue Farbstoff färbt Baumwolle aus  schwach alkalischem Bade, welchem noch  Kupfersulfat und     Natriumtartrat        zugegeben     worden sind, in     echten        braunstichig    roten  Tönen.  



       Beispiel:     22,8 Gewichtsteile     1-Oxy-2-aminobenzol-          4-ca.rbonsäurephenylamid    werden unter Zu  satz von 6,9     Gewichtsteilen        Natriumnitrit     und 27 Gewichtsteilen konzentrierter Salz  säure bei 0      diazotiert    und die     Diazoverbin-          dung    mit 60,7     Gewichtsteilen    des sekundären  Kondensationsproduktes aus 1     Mol        Cyanur-          chlorid,

Nach  4 Stunden wird der gebildete Farbstoff durch  Zusatz von Salzsäure abgeschieden und fil  triert. Der Filterrückstand wird als Natrium  salz gelöst. Aus der Lösung wird der Farb  stoff mit Kochsalz abgeschieden, filtriert und  getrocknet.

   Er     stellt    ein schwarzes Pulver  dar, das Baumwolle in schwach alkalischem  Bade in roten Tönen anfärbt. Durch Ver  setzen des Färbebades mit Kupfersalzlösung  aus     Kupfersulfat    und weinsaurem Natrium  schlägt der Farbton nach     braunstichig    rot um.  Die Färbung     ist    wasch- und lichtecht.



  <B> Additional patent </B> to main patent no. 245067. Process for the production of a noun azo dye. The subject of the present additional patent is a process for the production of a noun azo dye, characterized in that 1 mol of dia.zotierter 1-oxy-2-aminobenzene - 4 - carboxylic acid phenyl amide with 1 mol of the secondary condensation product from 1 mol of cyanuric chloride ,

       1 mol of 2-amino-5-oxynaphthalene-7-sulfonic acid and 1 mol of 4-amino-4'-oxy-1,1'-azobenzene-3'-carboxylic acid are combined in an alkaline medium.



  The new dye dyes cotton from a weakly alkaline bath to which copper sulphate and sodium tartrate have been added in real brownish red tones.



       Example: 22.8 parts by weight of 1-oxy-2-aminobenzene-4-ca.rboxylic acid phenylamide are diazotized at 0 with the addition of 6.9 parts by weight of sodium nitrite and 27 parts by weight of concentrated hydrochloric acid and the diazo compound with 60.7 parts by weight of the secondary Condensation product from 1 mol of cyanuric chloride,

      1 mol of 2-amino-5-oxynaphthalene-7-sulfonic acid and 1 mol of 4-amino-4'-oxy-1,1'-azobenzene-3'-carboxylic acid, de as the sodium salt with the addition of 100 parts by weight of 20% strength Caleiumhydroxyd were dissolved in 1000 parts by weight of water, combined. After 4 hours, the dye formed is deposited by adding hydrochloric acid and filtered. The filter residue is dissolved as sodium salt. The dye is precipitated from the solution with common salt, filtered and dried.

   It is a black powder that dyes cotton in a weakly alkaline bath in red tones. By adding a copper salt solution of copper sulphate and tartrate of sodium to the dye bath, the color changes to a brownish red. The color is washable and lightfast.
