Description

  

      Zusatzpatent    zum Hauptpatent Nr. 127259.         'erfahren    zur Herstellung eines     neuen        Farbstoffes.       Es wurde gefunden, dass man einen neuen       Farbstoff    erhält, wenn man     diazotierte    4  Acetamino-2-amino-l-benzolsulfosäure mit l.       (2'-Methyl-5'-sulfosäure)-phenyl-5-pyrazolon-          3-carbonsäure    kuppelt. Der so erhaltene Farb  stoff bildet ein gelbes Pulver. Er färbt Wolle  aus schwefelsaurem Bade in sehr gleich  mässigen, grüngelben Tönen. Die Färbungen  .sind sehr gut licht-, Wasser- und     alkaliecht     und halten der sauren Walke stand.  



  <I>Beispiel.:</I>  29,8 Teile     1-(2'-Methyl-5'-sulfosäure)-phe-          nyl-5-pyrazolon-3-carbonsäure    werden in 150  Teilen Wasser mit 20 Teilen     kalziniertem     Soda gelöst, mit Eis gekühlt und hierauf  mit der     Diazoverbindung    aus 23 Teilen     4-          Acetamino-2-amino-l-benzolsulfosäure    ver  setzt. Der sich bildende Farbstoff scheidet    sich teilweise aus. Durch Zusatz von Koch  salz wird die Fällung vervollständigt, dann  wird     möglichst    neutral gestellt,     filtriert    und  getrocknet.



      Additional patent to the main patent No. 127259. 'Learn about the production of a new dye. It has been found that a new dye is obtained if one diazotized 4-acetamino-2-amino-1-benzenesulfonic acid with l. (2'-methyl-5'-sulfonic acid) -phenyl-5-pyrazolone-3-carboxylic acid couples. The dye obtained in this way forms a yellow powder. He dyes wool from sulfuric acid bath in very even, green-yellow tones. The dyeings are very resistant to light, water and alkali and withstand acidic fulling.



  <I> Example: </I> 29.8 parts of 1- (2'-methyl-5'-sulfonic acid) -phenyl-5-pyrazolone-3-carboxylic acid 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 ver sets. The dye that forms is partially separated out. The precipitation is completed by adding sodium chloride, then the mixture is made as neutral as possible, filtered and dried.
