Description

  

      Zusatzpatent    zum Hauptpatent Nr. 175028.    Verfahren zur Herstellung eines neuen     Azofarbstoffes.       Es wurde gefunden, dass man einen neuen     Farbstoff    erhält, welcher der Formel  
EMI0001.0004     
         entspricht,    wenn man     diazotiertes        4-(3'-          :NTethyl)    -     phenoxyacetylamino    -2. 5-     diäthox@--          1-aminobenzol    mit dem     3-Chloranilid    der  2.     3-Oxynaphthoesä-ure    kuppelt.  



  Der neue Farbstoff bildet ein dunkel  blaues Pulver. Auf geeigneten Substraten;  wie zum Beispiel pflanzlichen Fasern, herge  stellt, färbt er diese in echten blauen Tönen.         Beispiel:          34,4    Teile     4-(3'-Methyl)-phenoxyacetyl-          amino-2.5-diäthoxy-l-aminobenzol    werden       wie    üblich     diazotiert    und in eine Lösung von  29,7 Teilen des     3-Chloranilids    der     2.3-          Oxynaphthoesäure,    60 Teilen 30%iger  Natronlauge, 30 Teilen Soda und 2000 Tei  len Wasser eingetragen. Der gebildete Farb  stoff fällt sofort aus.

   Der dunkelblaue Nie  derschlag wird filtriert und     getrocknet.  



      Additional patent to main patent No. 175028. Process for the production of a new azo dye. It has been found that a new dye is obtained which has the formula
EMI0001.0004
         corresponds if one diazotized 4- (3'-: NTethyl) - phenoxyacetylamino -2. 5- diäthox @ - 1-aminobenzene couples with the 3-chloroanilide of the 2nd 3-oxynaphthoic acid.



  The new dye forms a dark blue powder. On suitable substrates; such as vegetable fibers, he dyes them in real blue tones. Example: 34.4 parts of 4- (3'-methyl) -phenoxyacetyl-amino-2.5-diethoxy-1-aminobenzene are diazotized as usual and 60 parts in a solution of 29.7 parts of 3-chloroanilide of 2,3-oxynaphthoic acid 30% sodium hydroxide solution, 30 parts of soda and 2000 parts of water entered. The dye formed falls out immediately.

   The dark blue precipitate is filtered and dried.
