  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     5,6'-Dioxy-7,7'-disulfo-1,2,2',1'-dinaphtha-          zins    mit 2     Mol        diazotierter        4-Chlor-2-amino-          1-plier)o1-6-sulfosätit-e    kombiniert     und    den er  haltenen Farbstoff mit     ehromabgebenden     Mitteln behandelt.

           Dor    neue     ehromhaltige    Farbstoff ist  trocken ein dunkles Pulver, welches in  Wasser und in verdünnten Alkalien mit  grünblauer und in konzentrierter Schwefel  säure mit braunschwarzer Farbe löslich ist.  Baumwolle und Kunstseide, wie     Viscose,     werden aus     sodaalkalischem    Bade, Wolle  und Seide aus saurem Bade, in echten grün  grauen Tönen angefärbt.

      <I>Beispiel:</I>  47,2 Teile des     5,51-Dioxy-7,7'-disulfo-1,2,          2',1'-dinaphthazins    werden zusammen mit  25 Teilen Soda in<B>500</B> Teilen Wasser in    Lösung gebracht und mit dem     Diazokörper     aus 45 Teilen     4-Chlor-2-aminophenol-6-sulfo-          säure    kombiniert.  



  Man löst<B>92</B> Teile dieses     Farbstoffes    in  2500 Teilen Wasser und versetzt mit einer       Fluorchromlösung,    entsprechend<B>30</B> Teilen       Cr20,9.,    worauf<B>15</B> Stunden am     Rückflussküh-          ler    gekocht wird, Durch Eindampfen und  Fällen mit Kochsalz kann die neue Chrom  verbindung abgeschieden werden.



  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 5,6'-dioxy-7,7'-disulfo-1,2,2 ', 1'-dinaphthazine is used combined with 2 moles of diazotized 4-chloro-2-amino-1-plier) o1-6-sulfosätit-e and treated the dye obtained with Ehrom-donating agents.

           The new dyestuff containing Ehrom is a dry, dark powder which is soluble in water and in dilute alkalis with a green-blue color and in concentrated sulfuric acid with a brown-black color. Cotton and artificial silk, like viscose, are dyed from soda-alkaline bath, wool and silk from acidic bath, in real green-gray tones.

      <I> Example: </I> 47.2 parts of 5,51-dioxy-7,7'-disulfo-1,2, 2 ', 1'-dinaphthazins are converted into <B> 500 <together with 25 parts of soda / B> parts of water brought into solution and combined with the diazo body consisting of 45 parts of 4-chloro-2-aminophenol-6-sulfonic acid.



  <B> 92 </B> parts of this dye are dissolved in 2500 parts of water and a fluorochrome solution, corresponding to <B> 30 </B> parts of Cr20.9 - If it is boiled, the new chromium compound can be deposited by evaporation and precipitation with table salt.
