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-aminobenzol-l-karbonsäure    und     1-(3'-Sulfo-)          phenyl-3-inethyl-5-pyrazolon    mit chromab  gebenden Mitteln behandelt.  



  Der erhaltene metallhaltige     Farbstoff    stellt  ein braungelbes Pulver dar, das sich in Wasser  mit gelber Farbe löst und Wolle aus saurem  Bade in gleichmässigen echten gelben Tönen  färbt.    <I>Beispiel:</I>  52,6 'feile des     Azofarbstoffes    aus     diazo-          tierter        4-Sulfo-2-aminobenzol-l-karborisäure     und     1-(3'-Sulfo-)pheriyl-3-methyl-5-pyrazolon     werden mit 300 Teilen Wasser und 120  Teilen     einer    18     o/oigen        Chromsulfatlösung     mehrere     Stunden    unter     Rückfluss    zum Sieden    erhitzt.

   Die nach dem Abkühlen sich ab  scheidende     Chromverbindung    wird     abfiltriert     und getrocknet.



  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 using the azo dye from diazotized 4-sulfo-2-aminobenzene-1-carboxylic acid and 1- (3'-sulfo) phenyl-3-ynethyl-5-pyrazolone treated with chromium donating agents.



  The metal-containing dye obtained is a brown-yellow powder which dissolves in water with a yellow color and dyes wool from an acid bath in uniform, genuine yellow tones. <I> Example: </I> 52.6 'file of the azo dye from diazo- tated 4-sulfo-2-aminobenzene-1-carboric acid and 1- (3'-sulfo-) pheriyl-3-methyl-5-pyrazolone are refluxed for several hours with 300 parts of water and 120 parts of an 18% chromium sulfate solution.

   The chromium compound which separates out after cooling is filtered off and dried.
