  Verfahren zur Herstellung eines neuen     ehromhaltigen    Farbstoffes.    Es wurde gefunden,     dass    man einen neuen  wertvollen     ehromhaltigen    Farbstoff erhält,  wenn man     diazotierte        2-Amitio-l-oxybenzol-          4,6-disulfosäure    mit     1-Phenyl-3-methyl-5-          pyrazolon    vereinigt und den erhaltenen     Azo-          farbstoff    mit     ehromabgebenden    Mitteln be  handelt.  



  Der erhaltene     ehromhaltige    Farbstoff stellt  getrocknet ein gelbbraunes Pulver dar, löst  sich in Wasser mit     gelboranger,        in    wässeriger  Natronlauge mit     gelboranger,    in konzentrierter  Schwefelsäure mit gelber Farbe und färbt  Wolle in     schwefelsaurern    Färbebade in sehr  gleichmässigen     Orangetönen    von sehr guten  Echtheitseigenschaften.  



  <I>Beispiel:</I>  <B>26,9</B> Teile     2-Ainino-l-oxybenzol-4,6-disulfo-          säure    werden in 200 Teilen Wasser gelöst  beziehungsweise suspendiert und nach Zusatz  von<B>30</B> Teilen Salzsäure und Eis bei<B>0-5 0</B>  wie üblich mit<B>7</B> Teilen     Natriumnitrit        diazo-          tiert.    Man     lässt    nun die     Diazolbsung    unter    Rühren einlaufen in eine eiskalte Auflösung  von     17,4Teilei)        1-Phenyl-3-methyl-5-pyi-azolon     und<B>30</B> Teilen     Natriumcarbonat    in<B>300</B> Teilen  Wasser.

   Nach beendigter Kupplung wärmt  man auf<B>60 0</B> an, salzt den Farbstoff mit  Kochsalz aus, filtriert,     presst    und trocknet.  Er bildet ein     gelbstithig    rotes Pulver, das  sich in Wasser orangerot, in konzentrierter  Schwefelsäure rein gelb löst. Wolle wird aus  saurem Bade gelbbraun angefärbt; die Farbe  schlägt beim     Nachchromieren    nach Orange  rot um.  



  <B>95,2</B> Teile des so erhaltenen Farbstoffes  werden in 2000 Teilen Wasser kochend ge  löst, hernach mit 30,4 Teilen Chromoxyd,  in Form einer     Fluorchromlösung,    versetzt  und längere Zeit     rückfliessend    gekocht. Durch  Eindampfen- und     Kristallisierenlassen    wird  der Farbstoff gewonnen.



  Process for the preparation of a new Ehrom-containing dye. It has been found that a new valuable Ehrom-containing dye is obtained if diazotized 2-amino-1-oxybenzene-4,6-disulfonic acid is combined with 1-phenyl-3-methyl-5-pyrazolone and the resulting azo dye with Ehrom-donating Funds treated.



  The dyestuff containing Ehrom is a yellow-brown powder when dried, dissolves in water with yellow-orange, in aqueous sodium hydroxide solution with yellow-orange, in concentrated sulfuric acid with yellow color and dyes wool in a sulfuric-acid dyebath in very even orange tones with very good fastness properties.



  <I> Example: </I> <B> 26.9 </B> parts of 2-amino-1-oxybenzene-4,6-disulphonic acid are dissolved or suspended in 200 parts of water and, after the addition of <B> 30 parts hydrochloric acid and ice at <B> 0-5 0 </B> as usual with <B> 7 </B> parts sodium nitrite diazotized. The diazole solution is now allowed to run into an ice-cold solution of 17.4 parts of 1-phenyl-3-methyl-5-pyi-azolone and 30 parts of sodium carbonate in 300 parts Share water.

   When the coupling is complete, the mixture is warmed to <B> 60 0 </B>, the dye is salted out with sodium chloride, filtered, pressed and dried. It forms a yellowish red powder that dissolves orange-red in water and pure yellow in concentrated sulfuric acid. Wool is dyed yellow-brown from an acid bath; the color changes to orange red when chromium plating.



  95.2 parts of the dye thus obtained are dissolved at the boil in 2000 parts of water, 30.4 parts of chromium oxide, in the form of a fluorochrome solution, are then added and the mixture is refluxed for a long time. The dye is obtained by allowing it to evaporate and crystallize.
