  <B>Zusatzpatent</B> 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        2-          Arninobenzol-l-karbonsäur@e    und     1-(2'-Methyl-          4'-strlfo-)pltenyl-3-rnethyl-5-pyrazolorr    mit       ehrotnabgebenden    Mitteln behandelt.  



  Der erhaltene     rnetallhaitige    Farbstoff stellt  ein gelbbraunes Pulver, dar, das sich in Wasser  und     ver@dürrrtter        Sodalösung    mit gelber Farbe  löst und Wolle aus     saurem    Bade in gleich  mässigen, sehr- lichtechten, gelben Tönen färbt.

    <I>Beispiel:</I>  43,8 Teile     deb.        Azofarbstoffes    aus     diazo-          tierter        2-Auiinobenzol-l-karbor)säure    und     1-          (2'-        Metlry    l -4'- s     u        lfo-)        pheriyl-    3     -rnethyl-5-pyra-          zolon    werden mit 800 Teilen Wasser und 120  Teilen einer 18     o/oigeu        Chromsulfatlösung     mehrere Stunden unter     Rückfluss    zum Sieden    erhitzt.

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



  <B> Additional patent </B> 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 if the azo dye is obtained from diazotized 2-aminobenzene-1-carboxylic acid and 1- (2'-methyl-4'-strlfo-) pltenyl-3-methyl-5 -pyrazolorr treated with antagonistic agents.



  The metal-containing dye obtained is a yellow-brown powder, which dissolves in water and dry soda solution with a yellow color and dyes wool from an acid bath in uniform, very lightfast, yellow tones.

    <I> Example: </I> 43.8 parts deb. Azo dye from diazotized 2-Auiinobenzol-1-carbor) acid and 1- (2'-Metlry l -4'-su lfo-) pheriyl-3-methyl-5-pyrazolone with 800 parts of water and 120 parts an 18% chromium sulfate solution heated to boiling under reflux for several hours.

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

PATENTANSPRUCH: Verfahren zur Herstellung eines neuen metallhaltigen Farbstoffes, dadurch gekenn zeichnet, dass man den Azofarbstoff aus di- azotierter 2-Aminobenzol-l-karbonsäure und 1-(2'-Methyl-4'-strlfo-)pheny1-3-methyl-5-pyra- zolon mit chromabgebenden Mitteln behandelt. Der erhaltene metallhaltige Farbstoff stellt ein gelbbraunes Pulver dar, das sich in Wasser und verdünnter Sodalösung mit gelber Farbe löst und Wolle aus saurem Bade in gleich mässigen, sehr lichtechten, gelben Tönen färbt. PATENT CLAIM: Process for the production of a new metal-containing dye, characterized in that the azo dye is made from diazo-2-aminobenzene-1-carboxylic acid and 1- (2'-methyl-4'-strlfo-) pheny1-3-methyl- 5-pyrazolone treated with chromium-releasing agents. The metal-containing dye obtained is a yellow-brown powder which dissolves in water and dilute soda solution with a yellow color and dyes wool from an acid bath in uniform, very lightfast, yellow tones.
