  <B>Zusatzpatent</B>     zum    Hauptpatent Nr. 127259.    Verfahren zur Herstellung     eines    neuen     Farbstoffes.       Es wurde     gefunden,        daB    man einen neuen  Farbstoff erhält, wenn man     diazotierte        4-          Acetamino-2-amino-l-benzolsulfosäure    mit     1-          p-Sulfophenyl-3-methyl-5-pyrazolon    kuppelt.  Der so erhaltene Farbstoff bildet ein gelbes  Pulver. Er färbt Wolle aus schwefelsaurem  Bade in sehr gleichmässigen, rotgelben Tönen.

    Die Färbungen sind sehr gut     licht-,        wasser-          und        alkaliecht    und halten der sauren Walke  stand.  



  <I>Beispiel:</I>  25,5 Teile     1-p-Sulfophenyl-3-methyl-5-          pyrazolon    werden in 150 Teilen Wasser mit  20 Teilen     calcinierter    Soda gelöst, mit Eis  gekühlt und hierauf mit der     Diazoverbin-          dung    aus 23 Teilen     4-Acetamino-2-amino-l-          benzolsulfosäure    versetzt. Der sich bildende  Farbstoff scheidet sich teilweise aus. Durch    Zusatz von Kochsalz     wird    die Fällung     ver-          vollständigt,    dann wird möglichst neutral  gestellt,     filtriert    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 when diazotized 4-acetamino-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 dyeings are very resistant to light, water and alkali and withstand acidic fulling.



  <I> Example: </I> 25.5 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 23 Parts of 4-acetamino-2-amino-1-benzenesulfonic acid are added. The dye that forms is partially separated out. The precipitation is completed by adding sodium chloride, then it is made as neutral as possible, filtered and dried.
