Description

  

  <B>Zusatzpatent</B> zum Hauptpatent Nr. 153829.    Verfahren zur Herstellung eines neuen metallhaltigen     Farbstoffs.       Es wurde gefunden, dass man einen neuen  metallhaltigen     Farbstoff    erhält, wenn man  die Chromverbindung des     Monoazofarbstoffs     der Formel  
EMI0001.0004     
    in alkalischem Medium mit dianotierter 4  Aminobenzol-l-sulfosäure vereinigt.  



  Der erhaltene metallhaltige Farbstoff stellt  ein dunkel gefärbtes Pulver dar, das sich in  Wasser mit violetter, in verdünnten Alkalien  mit schwarzgrüner, in konzentrierter Schwe  felsäure mit schwarzvioletter Farbe löst und       Viscose    in schwarzvioletten bis     violettstichig     grauen Tönen färbt.  



  <I>Beispiel:</I>  50 Teile der Chromverbindung des durch  Kupplung in Gegenwart von Säure erhalte-         nen        Azofarbstoffs    aus dianotiertem     5-Nitro-          2-amino-l-phenol    und     2-Amirro-5-ogynaphta-          lin-7-sulfosäure    werden in 300 Teilen Wasser  zusammen mit 25 Teilen Soda gelöst und  bei 0-5   mit der     Diazolösung    aus 21 Teilen       4-Aminobenzol-l-sulfosäure    vereinigt. Nach  beendeter Kupplung wird wie üblich isoliert  und getrocknet.



  <B> Additional patent </B> to main patent no. 153829. Process for the production of a new metal-containing dye. It has been 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 dianotized 4-aminobenzene-1-sulfonic acid.



  The metal-containing dye obtained is a dark-colored powder which dissolves in water with violet, in dilute alkalis with black-green, in concentrated sulfuric acid with black-violet color and stains viscose in black-violet to violet-tinged gray tones.



  <I> Example: </I> 50 parts of the chromium compound of the azo dye obtained by coupling in the presence of acid from dianotated 5-nitro-2-amino-1-phenol and 2-amirro-5-ogynaphthalin-7- sulfonic acid are dissolved in 300 parts of water together with 25 parts of soda and combined at 0-5 with the diazo solution of 21 parts of 4-aminobenzene-1-sulfonic acid. After the coupling has ended, it is isolated and dried as usual.
