      Zusatzpatent    zum Hauptpatent Nr. 237397.    Verfahren zur Herstellung eines neuen     Polyazofarbstoffes.       Es wurde gefunden, dass man einen neuen       Polyazofarbstoff    erhält, wenn man 1     Mol          diazotierte;        1-Amino-5-chlorbenzol-2-carbon-          säure,    1     Mol        2-Amino-5-oxynaphthalin-7-sul-          fonsäure,    1     Mol        Cyanurchlorid    und 2     Mol        4-          Amino        -4'-;

  oxy        -1,1'-.azobenzol        -@3r-carbonsäure     derart aufeinander einwirken lässt, dass die       Diazoverbindung    in     6-Stellung    des Naphtha  linkerns eingreift, und das     Cyanurchlorid    die       Aminogruppe    des     Naphthalinderivates    und  diejenigen der beiden     Aminoazofarbstoffe     unter Bildung eines     ternären        Triazinkonden-          sationsproduktes    vereinigt.  



  Der neue Farbstoff stellt ein rotbraunes  Pulver dar und färbt Baumwolle in schwach  alkalischem Bade, das mit einer Kupfersalz  lösung aus Kupfersulfat und weinsaurem Na  trium versetzt wurde, in wasch- und licht  echten.     orangebraunen    Tönen an.         Beispiel:

       17,1 Gewichtsteile     1-Amino-5-chlorbenzol-          "-carbonsäure        werden    in 200 Gewichtsteilen  Wasser auf 40  erwärmt, 27 Gewichtsteile    konzentrierte Salzsäure- zugegeben, mit Eis  auf 5  gekühlt und mit 6,9 Gewichtsteilen       Natriumnitrit        diazotiert.    Die klare     Diazo-          lösung    wird mit 82,1 Gewichtsteilen des in  bekannter Weise hergestellten     Triazinpro-          duktes    aus 1     Mol        Cyanurchlorid,

      1     Mol        2-          Amino-5-oxynaphthalin    - 7 -     sulfonsäure,    und  2     Mol        4-Amino-4'-oxy-1,1'-azobenzol-3'-car-          bonsäure,    das in 1200 Teilen Wasser unter  Zusatz von 60 Gewichtsteilen     Natriumcarbo-          nat    gelöst wurde, gekuppelt. Man rührt einige  Stunden und fällt den gebildeten Farbstoff  mit Kochsalz.



      Additional patent to main patent No. 237397. Process for the production of a new polyazo dye. It has been found that a new polyazo dye is obtained if 1 mole is diazotized; 1-amino-5-chlorobenzene-2-carboxylic acid, 1 mol of 2-amino-5-oxynaphthalene-7-sulphonic acid, 1 mol of cyanuric chloride and 2 mol of 4-amino -4'-;

  oxy -1,1 '-. azobenzene - @ 3r-carboxylic acid can act on each other in such a way that the diazo compound intervenes in the 6-position of the naphtha linker, and the cyanuric chloride the amino group of the naphthalene derivative and those of the two aminoazo dyes to form a ternary triazine condensation product united.



  The new dye is a reddish brown powder and dyes cotton in a weakly alkaline bath to which a copper salt solution of copper sulfate and tartaric sodium has been added, in a washable and light-proof. orange-brown tones. Example:

       17.1 parts by weight of 1-amino-5-chlorobenzene-carboxylic acid are warmed to 40 in 200 parts by weight of water, 27 parts by weight of concentrated hydrochloric acid are added, the mixture is cooled to 5 with ice and diazotized with 6.9 parts by weight of sodium nitrite. The clear diazo solution is with 82.1 parts by weight of the triazine product prepared in a known manner from 1 mol of cyanuric chloride,

      1 mol of 2-amino-5-oxynaphthalene-7-sulfonic acid, and 2 mol of 4-amino-4'-oxy-1,1'-azobenzene-3'-carboxylic acid, which is dissolved in 1200 parts of water with the addition of 60 parts by weight Sodium carbonate was dissolved, coupled. The mixture is stirred for a few hours and the dyestuff formed is precipitated with sodium chloride.
