  verfahren zur     Darstellung    eines gelben     Chron        ilierfarbstofFes.       Es wurde gefunden, dass     man    einen Farb  stoff erhält, der auf Wolle mit     Chromat    be  handelt grünstickig gelbe Färbungen von  sehr guter Licht- und     Walkechtbeit    und her  vorragender     Karbonisiereclitheit    liefert, wenn  man     diazotierte        13        #        5-Dibroni-2-aniinobenzoe-          säure    mit     1(2-Chlor-5-sulfopheny        1)

  -3-methyl-5-          pyrazolon    kuppelt.  



  <I>Beispiel:</I>  295 Teile 3     #        5-Dibrom-2-aininobenzoesäiire     werden     diazotiert;    die     Diazolösung    wird in  eine     sodaallzalisehe    Lösung von 288,5 Teilen       1(2-Chlor-5-sulfoplienyl)-3-methyl-5-pyrazolon     eingerührt. Nach kurzem Anwärmen fällt der  Farbstoff beim Erkalten aus; die völlige Ab  acheidung erfolgt durch Aassalzen. Der aus-    gesalzene     Farbstoff    wird     abgepresst    und ge  trocknet.



  process for the preparation of a yellow chronicle dye. It has been found that a dye is obtained which, on wool with chromate, gives greenish yellow dyeings of very good light and boiling fastness and excellent carbonization properties if diazotized 13 # 5-dibroni-2-aniinobenzoic acid is mixed with 1 (2-chloro-5-sulfopheny 1)

  -3-methyl-5-pyrazolone couples.



  <I> Example: </I> 295 parts of 3 # 5-dibromo-2-aininobenzoic acid are diazotized; the diazo solution is stirred into a sodaallzalisehe solution of 288.5 parts of 1 (2-chloro-5-sulfoplienyl) -3-methyl-5-pyrazolone. After a short warm-up, the dye precipitates on cooling; the complete separation is done by carrion salts. The salted-out dye is pressed out and dried.
