  Zusatzpatent zum Hauptpatent     Nr.   <B>136650.</B>    Verfahren zur Herstellung eines neuen     Azofarbstoffes.       Es wurde gefunden,     dass    man einen  neuen Farbstoff erhält, wenn man<B>1</B>     Mol.     des     5,5'-Dioxy-7,7'-disulfo-1,2,2',1'-dinaphth-          azins    mit 2     Mol.        diazotierter        4-Nitro-2-amino-          1-phenol-6-suliosäure    kombiniert und den  erhaltenen Farbstoff mit     kupfer-    und     ehrom-          abgebenden    Mitteln behandelt.  



  Der neue     kupfer-    und     chromhaltige    Farb  stoff ist trocken ein dunkles Pulver, welches  sich in Wasser mit blauvioletter, in ver  dünnten Alkalien mit blauer und in konzen  trierter Schwefelsäure mit schwärzlicher  Farbe löst. Baumwolle wird aus     soda-          alkalischem        Glaubersalzbade    in grüngrauen  Tönen angefärbt.  



  <I>Beispiel:</I>  <B>90</B> Teile des     Disazofarbstoffes    aus dem       5,5'-Dic,xy-7,7'-disulfo-1,2,2',1'-dinaphthazin     und     4-Nitro-2-amino-l-phenol-6-sulfosäure     werden in<B>3500</B> Teilen Wasser gelöst und  mit Lösungen von<B>25</B> Teilen kristallisier  tem Kupfersulfat und     Fluorchrom,    entspre  chend<B>25</B> Teilen     Crf!0,    versetzt und das  Gemisch<B>16</B> Stunden am     Rückflusskühler       gekocht. Durch Zugabe von     Kochsalzlösung     wird die     Mischkomplexverbindung    abge  schieden.



  Additional patent to main patent no. <B> 136650. </B> Process for the production of a new azo dye. It has been found that a new dye is obtained if <B> 1 </B> mol. Of the 5,5'-dioxy-7,7'-disulfo-1,2,2 ', 1'-dinaphth- azine combined with 2 moles of diazotized 4-nitro-2-amino-1-phenol-6-sulioic acid and treated the resulting dye with copper and chromium-releasing agents.



  The new dye, which contains copper and chromium, is a dry, dark powder that dissolves in water with a blue-violet color, in diluted alkalis with a blue color and in concentrated sulfuric acid with a blackish color. Cotton is dyed from a soda-alkaline Glauber's salt bath in green-gray tones.



  <I> Example: </I> <B> 90 </B> parts of the disazo dye from the 5,5'-dic, xy-7,7'-disulfo-1,2,2 ', 1'-dinaphthazine and 4-Nitro-2-amino-1-phenol-6-sulfonic acid are dissolved in <B> 3500 </B> parts of water and mixed with solutions of <B> 25 </B> parts of crystallized copper sulfate and fluorochrome, accordingly B> 25 parts Crf! 0, added and the mixture boiled for 16 hours on the reflux condenser. The mixed complex compound is separated out by adding saline solution.
