Description

  

  Verfahren zur Herstellung eines neuen     ehromhaltigen        Färbstoffes.       Es wurde gefunden, dass man einen neuen  chromhaltigen Farbstoff erhält, wenn man  den     Azofarbstoff    aus dianotierter     l.-Amino-2-          ogynaphthalin-4,6-disulfonsäure    und 1-(3'  Sulfo-)     phenyl-3-methyl-5-pyrazolon    mit chrom  abgebenden Mitteln behandelt.  



  Der erhaltene chromhaltige Farbstoff stellt  ein dunkelrotes Pulver dar, das sich in Was  ser mit roter, in konzentrierter Schwefelsäure  mit gelber Farbe löst und Wolle aus saurem  Bade in sehr lichtechten, reinen     Rosätönen     färbt.  



       Beispiel:     62,9 Teile des     Azofarbstoffes    aus diano  tierter     1-Amino-2-oxynaphthalin-4,6-disulfori-          säure    und     1-(3'-Sulfo-)        phenyl-3-methyl-5-py-          razolon    werden in 250 Teilen Wasser gelöst  und nach Zugabe von 7,6 Teilen     Cr203,    in  Form einer     Fluorchromlösung,    drei Stunden    rückfliessend gekocht. Beim Erkalten scheidet  sich der Farbstoff zum grossen Teil in kristal  liner Form ab. Er wird     abfiltriert    und ge  trocknet.



  Process for the preparation of a new Ehrom-containing dye. It has been found that a new chromium-containing dye is obtained if the azo dye is obtained from dianotated l.-amino-2-ogynaphthalene-4,6-disulfonic acid and 1- (3 'sulfo) phenyl-3-methyl-5-pyrazolone treated with chrome releasing agents.



  The chromium-containing dye obtained is a dark red powder which dissolves in water with red in concentrated sulfuric acid with a yellow color and dyes wool from an acid bath in very lightfast, pure pink tones.



       Example: 62.9 parts of the azo dye from diano-tated 1-amino-2-oxynaphthalene-4,6-disulforic acid and 1- (3'-sulfo-) phenyl-3-methyl-5-pyrazolone are in 250 Dissolved parts of water and, after the addition of 7.6 parts of Cr203, in the form of a fluorochrome solution, refluxed for three hours. When it cools, most of the dye separates out in crystalline form. It is filtered off and dried ge.
