  Der neue Farbstoff     ist    in Wasser mit       vielettsühwarzer,    in<B>10 %</B>     iger        Natro-nla.u",-e     mit     rötlieh    braunvioletter und in konzen  trierter     Seliwefelsäure.    mit blauer Farbe     lös-          lieh.    Er färbt Wolle und Seide in schwarzen  Tönen an.  



  <I>Beispiel:</I>  Die nach dem Beispiel der     Patentsclirift,          Nr.   <B>13,0155</B> erhältliche Lösung der Chrom  verbindung des     Azofarbetoffes    aus, der  nitrierten     Diazoverbinclung    der     1-Amino-2-          oxyna,phtha,lin-4-sulfo,sä,ure    und     ss-Naplitho,1     wird vor dem     Aussalzen    mit<B>30</B> Teilen         NickeIsuffat    und<B>1</B> Teil     E"igsäure,    in 200  Teilen     Wmser    versetzt,<B>3</B> Stunden, auf<B>60 0</B>  erwärmt, filtriert und     ausgesalzen.  



  Additional patent to main patent No. 138024. Process for the production of a metal-containing azo dye. It has been found that a new metal-containing dye is obtained if the eliromha, -Itigen dye, which is obtained by treating the azo dye from the nitrated <B> 1 - </B> Diazo, <B> - </B> 2 <B> - </B> oxynaphtlialin <B> - </B> 4- sulfonic acid and fl-naphthol with chromium formate in the heat and.

   in the presence of sodium acetaf, treated with Niokelsalzen.



  The new dye is soluble in water with a lot of black, in <B> 10% </B> iger Natro-nla.u ", - e with reddish brown-violet and in concentrated seliulfuric acid with blue color. It dyes wool and silk in black tones.



  <I> Example: </I> The solution of the chromium compound of the azo dye from the nitrated diazo compound of 1-amino-2-oxyna, phtha, obtainable according to the example of the patent clirift, no. <B> 13.0155 </B> , lin-4-sulfo, sä, ure and ss-naplitho, 1 are mixed with <B> 30 </B> parts of nickel isuffate and <B> 1 </B> part of ferric acid in 200 parts of worm before salting out , <B> 3 </B> hours, heated to <B> 60 0 </B>, filtered and salted out.
