  Zusatzpatent     zum    Hauptpatent Nr. 237397.    Verfahren zur Herstellung eines neuen     Polyazofarbstoffes.       Es wurde gefunden, dass man einen neuen       Polyazofarbstoff    erhält, wenn man 1     Mol    di  anotierte     1-Aminobenzol-5-brombenzol-2-car-          bonsäure,    1     Mol        2-Amino-5-oxynaphthalin-7-          sulfonsäure,    1     Mol        Cyanurchlorid    und 2     Mol          4-Amino-4'-oxy-1,

  1'-azobenzol    -3'-     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 Lernären     Triazinkonden-          sationsproduktes    vereinigt.  



  Der neue     I'arbstoff    stellt ein rotbraunes  Pulver dar und färbt Baumwolle in schwach  alkalischem Bade, das mit einer Kupfersalz  lösung aus Kupfersulfat und weinsaurem  Natrium versetzt wurde, in wasch- und licht  echten     orangebraunen    Tönen an.  



  <I>Beispiel:</I>  21,6 Gewichtsteile     1-Amino-5-brombenzol-          9-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    dianotiert.

   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 of di-anotated 1-aminobenzene-5-bromobenzene-2-carboxylic acid, 1 mole of 2-amino-5-oxynaphthalene-7-sulfonic acid, 1 mole of cyanuric chloride and 2 Moles of 4-amino-4'-oxy-1,

  1'-azobenzene -3'-carboxylic acid can act on one another in such a way that the diazo compound intervenes in the 6-position of the naphtha linker, and the cyanuric chloride combines the amino group of the naphthalene derivative and those of the two aminoazo dyes to form a learning triazine condensation product.



  The new dye is a red-brown powder and dyes cotton in a weakly alkaline bath to which a copper salt solution of copper sulfate and tartrate of sodium has been added in washable and light orange-brown tones.



  <I> Example: </I> 21.6 parts by weight of 1-amino-5-bromobenzene-9-carboxylic acid are heated to 40 in 200 parts by weight of water, 27 parts by weight of concentrated hydrochloric acid are added, cooled to 5 with ice and 6.9 parts by weight Dianotized sodium nitrite.

   The clear diazo solution is mixed 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 was dissolved in 1200 parts of water with the addition of 60 parts by weight of sodium carbonate, coupled. The mixture is stirred for a few hours and the dyestuff formed is precipitated with sodium chloride.
