Description

  

  Verfahren zur Herstellung eines neuen metallhaltigen     Farbstores.       Es wurde gefunden, dass man einen neuen  metallhaltigen     .Farbstoff    erhält, wenn man  den     Disazofarbstoff    der Formel:  
EMI0001.0004     
    der durch Kuppeln von dianotierter     Anthra-          nilsäure    in saurem Medium mit     2-Amino-h-          oxynaphthalin-7-sulfosäure    und Einwirkung  von dianotierter     4-Nitro-2-amino-l-phenol-6-          sulfosäure    auf den entstandenen     Monoazo-          farbstoff    in     alkalisr;

  hem    Medium erhalten  werden kann, mit einem chromabgebenden  Mittel behandelt.  



  Der erhaltene metallhaltige Farbstoff stellt  ein dunkel gefärbtes Pulver dar, das sich in  Wasser mit blauer, in konzentrierter Schwe  felsäure mit     rötlichvioletter    Farbe löst und  Viskose in blaugrauen Tönen färbt.    <I>Beispiel:</I>  6,8 Teile des     Disazofarbstoffes,    erhalten  durch alkalische Kupplung von dianotierte       4-Nitro-2-amino-l-phenol-6-sulfosäure    mit dem  durch saure Kupplung aus dianotierter     An-          thranilsäure    und     2-Amino-5-oxynaphthalin-7-          sulfosäure    erhältlichen     Monoazofarbstoff,

      wer  den in 600 Teilen Wasser gelöst und nach  Zugabe einer     Fluorchromlösung,    entsprechend  3 Teilen     Cr20s,    einige Zeit rückfliessend ge  kocht. Die anfänglich rote Farbe der Lösung  geht bald nach Blau über. Nach beendeter       Chromierung    wird das überschüssige Chrom  durch     Zugabe    von Soda abgeschieden, die     Farb-          stofflösung    hierauf filtriert und zur Trockne  eingedampft.



  Process for the production of a new metal-containing stain. It has been found that a new metal-containing dye is obtained if the disazo dye of the formula:
EMI0001.0004
    by coupling dianotized anthranilic acid in acidic medium with 2-amino-h-oxynaphthalene-7-sulfonic acid and the action of dianotized 4-nitro-2-amino-1-phenol-6-sulfonic acid on the resulting monoazo dye in alkali ;

  hem medium can be obtained treated with a chromium donating agent.



  The metal-containing dye obtained is a dark-colored powder which dissolves in water with blue, in concentrated sulfuric acid with reddish-violet color and dyes viscose in blue-gray tones. <I> Example: </I> 6.8 parts of the disazo dye, obtained by alkaline coupling of dianotated 4-nitro-2-amino-1-phenol-6-sulfonic acid with the acidic coupling of dianotated anthranilic acid and 2- Amino-5-oxynaphthalene-7-sulfonic acid available monoazo dye,

      who dissolved in 600 parts of water and, after adding a fluorochrome solution, corresponding to 3 parts of Cr20s, refluxed for some time. The initially red color of the solution soon changes to blue. After the chromation is complete, the excess chromium is separated off by adding soda, the dye solution is then filtered and evaporated to dryness.
