Description

  

      Zusatzpatent    zum Hauptpatent Nr. 159942.    Verfahren zur Herstellung eines neuen     ehromhaltigen    Farbstoffes.    Es wurde gefunden, dass man einen neuen  chromhaltigen Farbstoff erhält, wenn man den       Azofarbstoff    aus     diazotierter        1-Amino-2-oxy-          naphthalin-4,6-disulfonsäure    und     1-Phenyl-3-          methyl-5-pyrazolon    mit chromabgebenden Mit  teln behandelt.  



  Der erhaltene chromhaltige Farbstoff stellt  ein dunkelrotes Pulver dar, das sich in kon  zentrierter Schwefelsäure mit orangegelber,  in Wasser mit     blaustichig-roter    Farbe löst  und Wolle aus saurem Bade in echten Rosa  tönen färbt.  



  <I>Beispiel:</I>  54,8 Teile des     Farbstoffes    aus     diazotierter          1-Amino-2-oxynaphthalin-4,6-disulfosäure    und       1-Phenyl-3-methyl-5-pyrazolon    (Mononatrium  salz) werden in 1000 Teilen Wasser gelöst  und nach Zugabe einer 5      /oigen        Fluorchrom-          lösung,    entsprechend 7,6 Teilen     Ors0s,    etwa    3 Stunden     rückfliessend    gekocht, durch Zugabe  von Kochsalz wird die Chromverbindung ab  geschieden.



      Additional patent to main patent No. 159942. Process for the production of a new Ehrom-containing dye. It has been found that a new chromium-containing dye is obtained if the azo dye from diazotized 1-amino-2-oxynaphthalene-4,6-disulfonic acid and 1-phenyl-3-methyl-5-pyrazolone is treated with chromium-releasing agents .



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



  <I> Example: </I> 54.8 parts of the dye from diazotized 1-amino-2-oxynaphthalene-4,6-disulfonic acid and 1-phenyl-3-methyl-5-pyrazolone (monosodium salt) are used in 1000 parts Dissolved water and, after adding a 5% fluorochromium solution, corresponding to 7.6 parts of OrsOs, refluxed for about 3 hours, the chromium compound is separated off by adding sodium chloride.
