Description

  

  Verfahren zur Herstellung eines neuen metallhaltigen     Farbstoffes.       Es. wurde gefunden,     dass    man einen neuen  metallhaltigen Farbstoff erhält, wenn man  die Chromverbindung des     Monoazofarbstoffes     der Formel:  
EMI0001.0004     
    in alkalischem Medium mit     diazotiertem          4-Nitro-l-aminobenzol    vereinigt.  



  Der erhaltene metallhaltige Farbstoff stellt  ein dunkelgefärbtes Pulver dar, das sich in  Wasser mit     schwärzlichblauer,    in konzen  trierter Schwefelsäure mit     schwärzlichvioletter     Farbe löst und Kunstseide aus regenerierter  Zellulose in echten grauen Tönen färbt.

      <I>Beispiel:</I>  <B>50</B> Teile der Chromverbindung des durch    Kupplung in Gegenwart von Säure erhaltenen       Azofarbstoffes    aus     diäzotiertem        5-Nitro-2-          amino-l-phenol    und     2-Amino-5-oxyriaphthaliii-          7-sulfosäure    werden in<B>300</B> Teilen Wasser  zusammen mit<B>25</B> Teilen Soda gelöst und  bei<B>0-5 0</B> mit der     Diazolbsung    aus<B>15</B>     gr          4-Nitro-l-aminobenzol    vereinigt. Der gebildete  Farbstoff wird abgeschieden und wie üblich  isoliert.



  Process for the production of a new metal-containing dye. It. it was found that a new metal-containing dye is obtained if the chromium compound of the monoazo dye of the formula:
EMI0001.0004
    combined in an alkaline medium with diazotized 4-nitro-1-aminobenzene.



  The metal-containing dye obtained is a dark-colored powder that dissolves in water with blackish-blue, in concentrated sulfuric acid with blackish-violet color and stains rayon from regenerated cellulose in real gray tones.

      <I> Example: </I> <B> 50 </B> parts of the chromium compound of the azo dye obtained by coupling in the presence of acid from diacetated 5-nitro-2-amino-1-phenol and 2-amino-5-oxyriaphthaliii - 7-sulfonic acid are dissolved in <B> 300 </B> parts of water together with <B> 25 </B> parts of soda and <B> 0-5 0 </B> with the diazole solution from <B> 15 </B> gr 4-nitro-l-aminobenzene combined. The dye formed is deposited and isolated as usual.
