Description

  

      Zusatzpatent    zum Hauptpatent Nr. 115111.    Verfahren     zur    Herstellung eines neuen     Farbstoffes.       Es,     wurde    gefunden, dass man einen  neuen, wertvollen Farbstoff erhält, wenn  man den     Azofarbstoff,    den man durch Kup  peln von 1     Mol.        diazotierter        Pikraminsäure     mit 1     Mol.        1-Naphthylamin-4-sulfosäure    er  halten kann, mit Chromacetat behandelt.

   Der  neue Farbstoff stellt ein schwärzliches Pul  ver dar und färbt Wolle aus schwefelsaurem  Bade in     dunkelolivegrünen    Tönen mit vor  züglichen Echtheitseigenschaften.  



  <I>Beispiel:</I>  48,9 Teile des     Natriumsalzes    des aus     di-          azotierter        Pikraminsäure    und     1-Naphthyl-          amin-4-sulfosäure    erhältlichen Farbstoffes  werden in 900 Teilen Wasser kochend ge  löst, mit 18 Teilen Chromoxyd in Form von  Chromacetat versetzt und längere Zeit rück-    fliessend gekocht. Durch Eindampfen und       Aussalzen    wird der neue chromhaltige Farb  stoff gewonnen.



      Additional patent to main patent No. 115111. Process for the production of a new dye. It has been found that a new, valuable dye is obtained if the azo dye, which can be obtained by coupling 1 mol of diazotized picric acid with 1 mol. 1-naphthylamine-4-sulfonic acid, treats the azo dye with chromium acetate.

   The new dye is a blackish powder and dyes wool from sulfuric acid bath in dark olive green tones with excellent fastness properties.



  <I> Example: </I> 48.9 parts of the sodium salt of the dye obtainable from diazoated picric acid and 1-naphthylamine-4-sulfonic acid are dissolved in 900 parts of water at the boil with 18 parts of chromium oxide in the form of chromium acetate offset and boiled back for a long time. The new chromium-containing dye is obtained through evaporation and salting out.
