  Verfahren zur Herstellung eines neuen chromhaltigen     Farbstoffes.       Es     -wurde    gefunden, dass man einen  neuen, chromhaltigen Farbstoff herstellen  kann, wenn man den     Azofarbstoff,    welcher  durch Vereinigen der nitrierten     Diazoverbin-          Jung    der     1-Amino-2-oxynaphtalin-4-sulfo-          säure    mit dem 1-     (3'-Sulfamido)        -phenyl-3-          nietliyl-5-pyrazolon    erhältlich ist, mit Fluor  chrom in der Wärme behandelt.

   Der neue,  chromhaltige Farbstoff bildet feine,     bron-          zierende    Kristalle; er löst sich in Wasser,  unter Zusatz von Soda oder von Natronlauge,  mit roter Farbe und färbt aus saurem Bade  Wolle sehr gleichmässig und echt gelbrosa.

    <I>Beispiel:</I>  570 Teile des     Farbstoffes    aus. der nitrierten       Diazoverbindung    der     1-Amino-2-oxynaphta-          lin-4-sulfosäure    und     1-(3'-Sulfamido)-phenyl-          3-methyl-5-pyrazolon    werden in der zwanzig  fachen     Menge    Wasser kochend gelöst, mit  einer     Fluorchrommenge,    entsprechend     22$     Teilen     Cr203,    versetzt und längere Zeit am         Rückflusskühler,    zweckmässig in Gegenwart  von Glas, gekocht.

   Hierauf lässt man abkühlen  und filtriert die     kristallisch        @ibgeschiedene          Chromverbindung.  



  Process for the production of a new chromium-containing dye. It has been found that a new chromium-containing dye can be produced if the azo dye, which is obtained by combining the nitrated diazo compounds of the 1-amino-2-oxynaphthalene-4-sulfonic acid with the 1- (3'- Sulfamido) -phenyl-3-nietliyl-5-pyrazolone is available, treated with fluorine chromium 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 wool very evenly and really yellow-pink.

    <I> Example: </I> 570 parts of the dye. the nitrated diazo compound of 1-amino-2-oxynaphthalene-4-sulfonic acid and 1- (3'-sulfamido) -phenyl-3-methyl-5-pyrazolone are dissolved in twenty times the amount of boiling water, with a fluorine chromium amount, corresponding to 22 parts of Cr203, added and boiled for a long time on the reflux condenser, expediently in the presence of glass.

   It is then allowed to cool and the crystalline chromium compound is filtered off.
