Description

  

      Zusatzpatent    zum Hauptpatent Nr. 163542.    Verfahren zur Herstellung eines neuen metallhaltigen Farbstoffes.    Es wurde gefunden, dass man einen neuen       metallhaltigen        Farbstoff'    erhalten kann, wenn  man den     Azofarbstoff    aus     diazotierter        4-Sulfo-          2-aminobettzol-l-karbonsäure    und     1-Phenyl-3-          methyl    - 5 -     pyrazolon    mit     chromabgebenden     Mitteln behandelt.  



  Der erhaltene metallhaltige     Farbstoff    stellt  ein dunkelgelbes Pulver dar, das sich in  Wasser mit gelber Farbe löst und Wolle aus  saurem Bade in     rotstichigen    Gelbtönen von  guten Echtheitseigenschaften färbt.  



  <I>Beispiel:</I>  18,9 Teile des     Azofarbstoffes    aus     dia7o-          tierter        4-Sulfo-2-aminobenzol-l-karbonsäure     und     1-Pltenyl-3-methyl-5-pyrazol <  i    werden in  <B>500</B> Teilen Wasser gelöst und mit 4,6 Teilen  Chromoxyd in Form von     Chlorfluorid    mehrere    Stunden rückfliessend gekocht. Man scheidet  sodann den     chromierten        Farbstoff    mit Koch  salz aus, filtriert und trocknet.



      Additional patent to main patent No. 163542. Process for the production of a new metal-containing dye. It has been found that a new metal-containing dye can be obtained by treating the azo dye from diazotized 4-sulfo-2-aminobettzole-1-carboxylic acid and 1-phenyl-3-methyl-5-pyrazolone with chromium-donating agents.



  The metal-containing dye obtained is a dark yellow powder which dissolves in water with a yellow color and dyes wool from an acid bath in reddish yellow shades with good fastness properties.



  <I> Example: </I> 18.9 parts of the azo dye from dia7otated 4-sulfo-2-aminobenzene-1-carboxylic acid and 1-pltenyl-3-methyl-5-pyrazole are used in 500 </B> Parts of water dissolved and refluxed for several hours with 4.6 parts of chromium oxide in the form of chlorofluoride. The chromized dye is then separated out with sodium chloride, filtered and dried.
