Description

  

      Zusatzpatent    zum Hauptpatent Nr. 145448.         Verfahren    zur Herstellung eines neuen metallhaltigen     Farbstoffes.       Es wurde gefunden, dass man einen neuen  metallhaltigen Farbstoff erhält, wenn man  den     Disazofarbstoff    der Formel:

    
EMI0001.0005     
    der durch Kuppeln von     diazotierter        Anthra-          nilsäure    in saurem Medium mit     2-Amino-5-          oxynaphthalin-7-sulfosäure    und Einwirkung  von     diazotierter        6-Nitro-2-amino-l-phenol-4-          sulfosäure    auf den entstandenen     Monoazofarb-          stoff    in alkalischem Medium erhalten werden  kann, mit einem     kupfer-    und einem chrom  abgebenden Mittel behandelt.  



  Der erhaltene metallhaltige Farbstoff stellt  ein dunkel gefärbtes Pulver dar, das sich in  Wasser mit violetter, in konzentrierter Schwe  felsäure mit rotvioletter Farbe löst und Vis  kose in egalen, grauvioletten Tönen färbt.    <I>Beispiel:</I>    6,8 Teile des Farbstoffes aus     diazotierter          6-Nitro-2-amino-l-phenol-4-sulfosäure    und dem       Monoazofarbstoff,    erhalten durch saure Kupp  lung von     diazotierter        Anthranilsäure    mit 2  Amino-5-oxynaphthalin-7-sulfosäure, werden  in 200 Teilen Wasser gelöst . und nach Zu  gabe von etwas Ammoniak mit 1,25 Teilen       CuS04    als     Kupferoxydammoniaklösung    wäh  rend kurzer Zeit behandelt.

   Der     Farbstoff     wird durch Essigsäure abgeschieden. Er wird  neuerdings in 600 Teilen Wasser gelöst und  mit 2,2 Teilen     Cr20s    als     Fluorchromlösung     rückfliessend gekocht, bis     Chromierung    erfolgt  ist. Der Farbstoff wird, eventuell nach vor  herigem Eindampfen, durch Salz abgeschieden.



      Additional patent to main patent no. 145448. Process for the production of a new metal-containing dye. It has been found that a new metal-containing dye is obtained by using the disazo dye of the formula:

    
EMI0001.0005
    by coupling diazotized anthranilic acid in an acidic medium with 2-amino-5-oxynaphthalene-7-sulfonic acid and the action of diazotized 6-nitro-2-amino-1-phenol-4-sulfonic acid on the resulting monoazo dye in alkaline Medium can be obtained treated with a copper and a chromium donating agent.



  The metal-containing dye obtained is a dark-colored powder which dissolves in water with violet, in concentrated sulfuric acid with red-violet color and stains viscose in level, gray-violet tones. <I> Example: </I> 6.8 parts of the dye from diazotized 6-nitro-2-amino-1-phenol-4-sulfonic acid and the monoazo dye, obtained by acid coupling of diazotized anthranilic acid with 2 amino-5- oxynaphthalene-7-sulfonic acid are dissolved in 200 parts of water. and after adding a little ammonia, treated with 1.25 parts of CuS04 as a copper oxide ammonia solution for a short time.

   The dye is deposited by acetic acid. It has recently been dissolved in 600 parts of water and refluxed with 2.2 parts of Cr20s as a fluorochrome solution until chromation has taken place. The dye is deposited by salt, possibly after prior evaporation.
