  Verfahren zur Herstellung eines     ehromhaltigen    Farbstoffes.    Es wurde gefunden, dass man einen       neuen,        ehromhaltigen        Farbstoff    herstellen  kann, wenn man den     Azofarbstoff,    welcher  durch Vereinigen der     Diazoverbindung    der  1-     Amino-2-oxynaphtalin-4-sulfos@iure    mit  dem     1-(3'-Sulfamido)-phenyl-3-methyl-5-          py        razolon    erhältlich ist, mit Chromacetat in  der     Wärine    behandelt.

   Der neue,     chrom-          haltige        Farbstoff    bildet feine,     bronzierende     Kristalle; er löst sich in Wasser unter Zu  satz von Soda oder von Natronlauge mit roter       Farbe    und färbt aus saurem Bade     urolle     sehr gleichmässig und echt     reinrosa.     



       Beispiel:     525 Teile des     Farbstoffes    aus der     Diazo-          verbinOung    der     1-Amino-2-oxynaplitalin-4-          sulfosäure    und     1-(3'-Sulfamido)-phenyl-3-          methyl-5-pyrazolon    werden in der 15fachen  Menge Wasser kochend gelöst, mit einer       Chromacetatmenge,    entsprechend 190 Teilen         Cr203,    versetzt und längere Zeit am Rück  flusskühler gekocht. Hierauf lässt man ab  kühlen und filtriert die kristallinisch ab  geschiedene Chromverbindung.



  Process for the preparation of a dye containing Ehrom. It has been found that a new, Ehrom-containing dye can be prepared if the azo dye, which is obtained by combining the diazo compound of the 1-amino-2-oxynaphthalene-4-sulfos @ iure with the 1- (3'-sulfamido) -phenyl -3-methyl-5- py razolon is available, treated with chromium acetate in the heat.

   The new, chromium-containing dye forms fine, bronzing crystals; it dissolves in water with the addition of soda or caustic soda with a red color and turns acidic bath roll very evenly and really pure pink.



       Example: 525 parts of the dye from the diazo compound of 1-amino-2-oxynaplitalin-4-sulfonic acid and 1- (3'-sulfamido) -phenyl-3-methyl-5-pyrazolone are dissolved in 15 times the amount of boiling water , with an amount of chromium acetate corresponding to 190 parts of Cr203, and boiled for a long time on the reflux condenser. It is then allowed to cool and the crystalline chromium compound which has separated out is filtered off.

PATENTANSPRUCH: Verfahren zur Herstellung eines neuen, chromhaltigen Farbstoffes, dadurch gekenn zeichnet, dass der Azofarbstoff, welcher durch Vereinigen der Diäzoverbindung der 1- Amino - 2 - oxynaphtalin- 4- sulf osäure mit dem 1-(3'-Sulfamido)-phenyl-3-methyl-5- pyrazolon erhältlich ist, mit Chromacetat in der Wärme behandelt wird. PATENT CLAIM: Process for the production of a new, chromium-containing dye, characterized in that the azo dye, which is obtained by combining the diazo compound of the 1- amino-2-oxynaphthalene-4- sulfonic acid with the 1- (3'-sulfamido) -phenyl- 3-methyl-5-pyrazolone is available that is heat treated with chromium acetate. Der neue, chrom- haltige Farbstoff bildet feine, bronzierende Kristalle; er löst sich in Wasser unter Zu satz von Soda oder von Natronlauge mit roter Farbe und färbt aus saurem Bade Wolle sehr gleichmässig und echt reinrosa. The new, chromium-containing dye forms fine, bronzing crystals; It dissolves in water with the addition of soda or caustic soda with a red color and turns acidic bath wool very evenly and really pure pink.
