  <B>Zusatzpatent</B> zum Hauptpatent Nr.<B>117996.</B>         Verfahren    zur Herstellung eines neuen     Farbstoffes.       Es wurde gefunden, dass man einen neuen  Farbstoff erhält, wenn man das     6-Nitro-\2-          amino    - 1 -     oxybenzol-4-sulfamid        diazotiert,     hierauf mit     1-(3'-Sulfamido)-phenyl-3-me-          thyl-5-pyrazolon    kuppelt und den so erhal  tenen Farbstoff mit Chromacetat behandelt.

    Der neue Farbstoff bildet ein     orangebraunes     Pulver, löst sich in Wasser und in 10     %iger     Natronlauge     mit    oranger, in konzentrierter  Schwefelsäure mit gelber Farbe und färbt  Wolle aus saurem Bade in orangen     '.Tönen     mit vorzüglichen Eigenschaften.  



  <I>Beispiel:</I>       233    Teile     6-Nitro-2-amino-l-oxybenzol-          4-sulfamid    werden in üblicher Weise mit 69  Teilen     Natriumnitrit        @diazotiert.    Die     Diazo-          lösung    lässt man in eine eiskalte Lösung von       253    Teilen 1 -     (3'-Sulfamido)-phenyl-3-me-          thyl-5-pyrazolon    und 300 Teilen Soda in  2500 Teilen Wasser unter Rühren einflie  ssen. Die Reaktionsmasse wird nach vollen  deter Kupplung auf<B>50'</B> angewärmt, der  Farbstoff mit Kochsalz     ausgesalzen    und in  der üblichen Weise isoliert.

      49,7 Teile des so erhaltenen Farbstoffes  werden in 500 Teilen heissem Wasser ge  löst, mit einer     Chromacetatlösung    entspre  chend 15,2 Teilen     Cr203    versetzt und län  gere Zeit am     Rückflusskühler    gekocht. Hier  auf wird die Chromverbindung durch Aus  salzen gewonnen.



  <B> Additional patent </B> to main patent no. <B> 117996. </B> Process for the production of a new dye. It has been found that a new dye is obtained if the 6-nitro- \ 2-amino-1-oxybenzene-4-sulfamide is diazotized, then with 1- (3'-sulfamido) -phenyl-3-methyl -5-pyrazolone couples and treated the dye obtained in this way with chromium acetate.

    The new dye forms an orange-brown powder, dissolves in water and in 10% sodium hydroxide solution with orange, in concentrated sulfuric acid with yellow color and dyes wool from acid baths in orange shades with excellent properties.



  <I> Example: </I> 233 parts of 6-nitro-2-amino-1-oxybenzene-4-sulfamide are diazotized in the customary manner with 69 parts of sodium nitrite. The diazo solution is allowed to flow into an ice-cold solution of 253 parts of 1- (3'-sulfamido) -phenyl-3-methyl-5-pyrazolone and 300 parts of soda in 2500 parts of water with stirring. After coupling is complete, the reaction mass is warmed to <B> 50 '</B>, the dye is salted out with common salt and isolated in the usual way.

      49.7 parts of the dye thus obtained are dissolved in 500 parts of hot water, a chromium acetate solution corresponding to 15.2 parts of Cr 2 O 3 is added and the mixture is refluxed for a longer time. Here the chromium compound is obtained by salting out.
