  <B>Zusatzpatent</B> zum Hauptpatent Nr. 127259.    Verfahren zur Herstellung eines neuen     Farbstoffes.       Es wurde gefunden, dass man     einen    neuen  Farbstoff erhält, wenn man     diazotierte        4-          Benzoylamino    - 2 -     amino    -1-     benzolsulfosäure     mit     1-p-Sulf        ophenyl    -3-     methyl    -5-     pyrazolon     kuppelt. Der so erhaltene Farbstoff bil  det ein gelbes Pulver.

   Er färbt Wolle aus  schwefelsaurem Bade in sehr gleichmässigen,  rotgelben Tönen, Die Färbungen sind sehr  gut licht-,     wasser-,    wasch- und     alkaliechtund     halten der sauren Walke stand.    <I>Beispiel:</I>  <B>25,5</B> Teile     1-p-Sulfophenyl-3-methyl-5-pyr-          azolonwerden    in 150 Teilen Wasser mit 20 Tei  len     calciniertenSoda    gelöst,     mitEisgekühltund     hierauf mit der     Diazoverbindung    aus<B>29,2</B> Tei  len 4 -     Benzoylamino    -2-     amino    -1-     benzolsulfo-          säure    versetzt.

   Der sich bildende Farbstoff  scheidet sich teilweise aus. Durch Zusatz von    Kochsalz wird die Fällung     vervollständigt,     dann wird     möglichst    neutral gestellt, fil  triert und getrocknet.



  <B> Additional patent </B> to main patent no. 127259. Process for the production of a new dye. It has been found that a new dye is obtained if diazotized 4-benzoylamino-2-amino-1-benzenesulfonic acid is coupled with 1-p-sulfophenyl -3-methyl -5-pyrazolone. The dye thus obtained forms a yellow powder.

   He dyes wool from sulfuric acid bath in very even, red-yellow tones. The dyes are very light, water, wash and alkali fast and withstand acid fulling. <I> Example: </I> <B> 25.5 </B> parts of 1-p-sulfophenyl-3-methyl-5-pyrazolone are dissolved in 150 parts of water with 20 parts of calcined soda, cooled with ice and then with the Diazo compound from 29.2 parts of 4-benzoylamino -2-amino -1-benzenesulfonic acid added.

   The dye that forms is partially separated out. The precipitation is completed by adding table salt, then it is made as neutral as possible, filtered and dried.
