Description

  

  Zusatzpatent zum Hauptpatent Nr. 127259.    Verfahren zur Herstellung eines neuen Farbstoffes.    Es wurde gefunden, dass man einen neuen  Farbstoff erhält, wenn man     diazotierte        4-          A.cetamino-2-a:mino-l-benzolsulfosäure    mit     1-          m-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-m-Sulfophenyl-3-methvl-5-          pyrazolon    werden in 150 Teilen Wasser mit  20 Teilen     calcinierter    Soda gelöst, mit Eis  gekühlt und hierauf mit der     Diazoverbindung     aus 23 Teilen     4-Acetamino-2-amino-l-benzol-          sulfosäure    versetzt. Der sich bildende Farb-         stoff    scheidet sich teilweise aus. Durch Zu  satz von Kochsalz wird die Fällung vervoll  ständigt, dann wird möglichst neutral ge  stellt,     filtriert        und    getrocknet.



  Additional patent 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-a-acetamino-2-a: mino-1-benzenesulfonic acid is coupled with 1-m-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-m-sulfophenyl-3-methvl-5-pyrazolone are dissolved in 150 parts of water with 20 parts of calcined soda, cooled with ice and then mixed with the diazo compound from 23 parts of 4 -Acetamino-2-amino-1-benzene sulfonic acid added. The dye that forms is partially eliminated. The precipitation is completed by adding table salt, then it is made as neutral as possible, filtered and dried.
