Description

  

      Verfahren    zur Herstellung eines neuen     eliromhaltigen    Farbstoffes.    Es wurde gefunden, dass man einen neuen  chromhaltigen Farbstoff erhält, wenn man  den     Azofarbstoff    aus dianotierter     1-Amino-          2-ogynaphthalin-4,6-disulfonsäure    und     1-(Phe-          nyl-3'-sulfamid-)3-methyl-5-pyrazolori    mit       ehromabgebenden    Mitteln behandelt.  



  Der erhaltene chromhaltige     Farbstoff    stellt  ein hellbraunes Pulver dar, das sich in Wasser  mit roter, in konzentrierter Schwefelsäure       lnit    orangegelber Farbe löst und Wolle aus  schwefelsaurem Bade in echten reinen     Rosa-          tünen    färbt.  



  <I>Beispiel:</I>  62,8 Teile des     iVIononatriumsalzes    des       l@\arbstoffes    aus dianotierter     1-Amiilo-2-ogy-          liilphthalin-4,6-disulfonsäure    und     1-(Phenyl-3'-          sulfamid-)3-methyl-5-pyrazolon    werden in 500  Teilen Wasser gelöst und nach Zugabe einer  1.0     "loigen        Chromsulfatlösung,    entsprechend       7,(;    Teilen     Cr20s,    2 Stunden rückfliessend    gekocht. Beim Erkalten scheidet sich ein  Teil des Farbstoffes in kristalliner Form ab.  Er wird     abfiltriert    und getrocknet.



      Process for the production of a new dye containing elirom. It has been found that a new chromium-containing dye is obtained when the azo dye is obtained from dianotated 1-amino-2-ogynaphthalene-4,6-disulfonic acid and 1- (phenyl-3'-sulfamide-) 3-methyl-5 -pyrazolori treated with Ehroma-donating agents.



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



  <I> Example: </I> 62.8 parts of the iVIonosodium salt of the dye from dianotated 1-amilo-2-ogylilphthalin-4,6-disulfonic acid and 1- (phenyl-3'-sulfamide) 3 -methyl-5-pyrazolone are dissolved in 500 parts of water and, after adding a 1.0 "solution of chromium sulfate, corresponding to 7 (; parts of Cr20s, refluxed for 2 hours. When it cools, part of the dye separates out in crystalline form. It is filtered off and dried.
