Description

  

  <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  Carboxäthylamino - 2 -     amino-1        -benzolsulfo-          säure    mit     1-(2'-Methyl-4'-sulfosäure)-phenyl-          5-pyrazolon-3-carbonsäure    kuppelt. Der so  erhaltene Farbstoff bildet ein gelbes Pulver.  Er färbt Wolle aus schwefelsaurem Bade in  sehr gleichmässigen, 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-4'-sulfosäure)          -phenyl-5-pyrazolon-3-carbonsäure    werden in  150 Teilen Wasser mit 20 Teilen     calcinierter     Soda gelöst, mit Eis gekühlt und hierauf mit  der     Diazoverbindung    aus 26 Teilen     4-Car-          boxäthylamino-    2     -amino-    1     -benzolsulfosäure     versetzt. Der sieh bildende Farbstoff scheidet    sich teilweise aus. Durch Zusatz von Koch  salz wird die Fällung vervollständigt, 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 if diazotized 4-carboxethylamino-2-amino-1-benzenesulfonic acid is used with 1- (2'-methyl-4'-sulfonic acid) -phenyl-5-pyrazolone-3-carboxylic acid clutch. The dye thus obtained 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-4'-sulfonic acid) -phenyl-5-pyrazolone-3-carboxylic acid are dissolved in 150 parts of water with 20 parts of calcined soda, with ice cooled and then mixed with the diazo compound from 26 parts of 4-carboxylamino-2-amino-1-benzenesulfonic acid. The color that forms the appearance is partially separated out. The precipitation is completed by the addition of cooking salt, which is then made as neutral as possible. filtered and dried.

PATENTANSPRUCH: Verfahren zur Herstellung eines neuen Farbstoffes, dadurch gekennzeichnet, dass man diazotierte 4-Carboxäthylamino-2-ami- no-l-benzolsulfosäure mit 1-(2'-Methyl-4'- sulfosäure)-phenyl-5-pyrazolon-3-carbonsäure kuppelt. Der so erhaltene Farbstoff bildet ein gelbes Pulver. Er färbt Wolle aus schwe felsaurem Bade in sehr gleichmässigen, grün gelben Tönen. Die Färbungen sind sehr gut licht-, Wasser- und alkaliecht und halten der sauren Walke stand. Claim: process for the preparation of a new dye, characterized in that diazotized 4-carboxethylamino-2-amino-1-benzenesulfonic acid with 1- (2'-methyl-4'-sulfonic acid) -phenyl-5-pyrazolone-3 -carboxylic acid couples. The dye thus obtained 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.
