  verfahren zur Herstellung eines neuen metallhaltigen     Farbstoffes.       Es wurde gefunden, dass man einen neuen  metallhaltigen Farbstoff erhalten kann, wenn       rnan    den     Azofarbstoff    aus     diazotierter        4-          Äthoxy-2-arnino-l-benzoesäure    und 1-(2'.5'  Disulfo-)phenyl-3-methyl-5-pyrazolon mit  chromabgebenden     11Zitteln    behandelt.  



  Der erhaltene metallhaltige Farbstoff stellt  ein gelbbraunes Pulver dar, das sich in Was  ser, 10     %iger        Sodalösung    oder Natronlauge  und in konzentrierter Schwefelsäure mit gel  ber Farbe löst. Er     f.'#Lrbt    Wolle aus schwefel  saurem Bade sehr gleichmässig in     grünstichig-          gelben    licht- und     walkechten    Tönen.  



  <I>Beispiel:</I>  Der aus 181 Teilen     4-Äthoxy-2-amirio-l.-          benzoesäure        und-340    Teilen     1-(2'.5'-Disulfo-)-          pherry        1-3-methyl-5-pyrazolon    in üblicher Weise  hergestellte     Azofarbstoff    wird mit 5000 Tei  len Wasser und 800 Teilen einer Chrom  sulfatlösung, die 84 Teile Chromoxyd ent  hält, längere Zeit unter     Rückfluss    zum Sieden    erhitzt. Nach beendeter     Chromierung    wird  die     Farbstofflösung    mit Soda schwach alka  lisch gemacht, filtriert und das Filtrat im  Vakuum zur Trockne eingedampft.



  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 from diazotized 4-ethoxy-2-amino-1-benzoic acid and 1- (2'.5 'disulfo) phenyl-3-methyl-5- pyrazolone treated with chromium-releasing agents.



  The metal-containing dye obtained is a yellow-brown powder which dissolves in water, 10% soda solution or sodium hydroxide solution and in concentrated sulfuric acid with a yellow color. He f. '# Changes wool from acidic sulfuric baths very evenly in greenish, yellow, lightfast and whackfast tones.



  <I> Example: </I> The one composed of 181 parts of 4-ethoxy-2-amirio-l-benzoic acid and 340 parts of 1- (2'.5'-disulfo) - pherry 1-3-methyl-5 pyrazolone prepared in the usual way is heated to boiling under reflux for a long time with 5000 parts of water and 800 parts of a chromium sulfate solution containing 84 parts of chromium oxide. When the chromation is complete, the dye solution is made weakly alkaline with soda, filtered and the filtrate is evaporated to dryness in vacuo.
