Description

  

  <B>Zusatzpatent</B> zum     Hauptpatent    Nr. 152881.         Yerfaluen    zur Herstellung eines neuen     Azofarbstoffes.       Es wurde gefunden, dass man einen neuen       Farbstoff    erhält, welcher der Formel:  
EMI0001.0005     
    entspricht, wenn man     diazotiertes        3-(1'-          Methyl)    -     phenoxyacetylamino    - 2 . 5     -dimethyl-          1-aminobenzol    mit dem     Anilid    der 2 .     3-Oxy-          naphthoesäure    kuppelt.  



  Der neue Farbstoff bildet ein rotes Pulver.  Auf geeigneten Substraten, wie zum Beispiel  pflanzlichen Fasern, hergestellt, färbt er diese  in echten blauroten Tönen.  



  <I>Beispiel:</I>  28,4 Teile     3-(1'-Methyl)-phenoxyacetyl-          amino-2.5-dimethyl-l-aminobenzol    werden  wie üblich     diazotiert    und in eine Lösung von  26,3 Teilen des     Anilids    der 2 .     3-Oxynaph-          tiloesäure,    50 Teilen 30     o/oiger    Natronlauge,  30 Teilen Soda und 2000 Teilen Wasser ein-    getragen. Der gebildete Farbstoff fällt sofort  aus. Der rote Niederschlag wird filtriert und  getrocknet.



  <B> Additional patent </B> to main patent No. 152881. Yerfaluen for the production of a new azo dye. It has been found that a new dye is obtained which has the formula:
EMI0001.0005
    corresponds if you diazotized 3- (1'-methyl) - phenoxyacetylamino - 2. 5-dimethyl-1-aminobenzene with the anilide of the 2nd 3-oxynaphthoic acid couples.



  The new dye forms a red powder. Produced on suitable substrates, such as vegetable fibers, he dyes them in real blue-red tones.



  <I> Example: </I> 28.4 parts of 3- (1'-methyl) -phenoxyacetyl-amino-2,5-dimethyl-1-aminobenzene are diazotized as usual and poured into a solution of 26.3 parts of the anilide of the 2nd . 3-oxynaphthiloic acid, 50 parts of 30% sodium hydroxide solution, 30 parts of soda and 2000 parts of water were introduced. The dye formed precipitates immediately. The red precipitate is filtered and dried.

PATENTANSPRUCH: Verfahren zur Herstellung eines neuen Farbstoffes, welcher der Formel EMI0001.0023 entspricht, dadurch gekennzeichnet, dass man diazotiertes 3-(1'-Methyl)-phenoxyacetylamirro- 2.5-dimethyl-l-aminobenzol mit dem Anilid der 2. 3-Oxynaphthoesäure kuppelt. Der neue Farbstoff bildet ein rotes Pulver. Auf geeigneten Substraten, wie zum Beispiel pflanzlichen Fasern, hergestellt, färbt er diese in echten blauroten Tönen. PATENT CLAIM: Process for the production of a new dye, which of the formula EMI0001.0023 corresponds, characterized in that diazotized 3- (1'-methyl) -phenoxyacetylamirro-2.5-dimethyl-l-aminobenzene is coupled with the anilide of 2. 3-oxynaphthoic acid. The new dye forms a red powder. Produced on suitable substrates, such as vegetable fibers, he dyes them in real blue-red tones.
