Description

  

  <B>Zusatzpatent</B> zum Hauptpatent     Nr.152881.       Verfahren     zur    Herstellung eines neuen     Azofarbstoffes.       Es wurde gefunden, dass man einen neuen       Farbstoff    erhält, welcher der Formel:  
EMI0001.0005     
    entspricht, wenn man dianotiertes 4-(1'  Methyl)-phenoxyacetylamino -2 . 5-     dimethoxy-          1-aminobenzol    mit dem     m-Nitranilid    der     2.3-          Oxynaphthoesäure    kuppelt.  



  Der neue     Farbstoff    bildet ein dunkel  violettes Pulver. Auf geeigneten Substraten,  wie zum Beispiel pflanzlichen     Fasern,    herge  stellt, färbt er diese in echten blauvioletten  Tönen.  



  <I>Beispiel:</I>  31,6 Teile     4-(1'-Methyl)-phenoxyacetyl-          amino-2.5-dimethoxy-l-aminobenzol    werden    wie üblich dianotiert und in eine Lösung von  30,8 Teilen des     m-Nitranilids    der     2.3-Oxy-          naphthoesäure,    50 Teilen 30      /oiger    Natron  lauge, 30 Teilen Soda und 2000 Teilen  Wasser eingetragen. Der gebildete     Farbstoff     fällt sofort aus. Der dunkelviolette Nieder  schlag wird filtriert und getrocknet.



  <B> Additional patent </B> to main patent number 152881. Process 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 one dianotated 4- (1 'methyl) -phenoxyacetylamino -2. 5- dimethoxy- 1-aminobenzene couples with the m-nitroanilide of 2,3-oxynaphthoic acid.



  The new dye forms a dark purple powder. On suitable substrates, such as vegetable fibers, he dyes them in real blue-violet tones.



  <I> Example: </I> 31.6 parts of 4- (1'-methyl) -phenoxyacetyl-amino-2,5-dimethoxy-1-aminobenzene are dianotized as usual and in a solution of 30.8 parts of the m-nitroanilide the 2,3-oxynaphthoic acid, 50 parts of 30% sodium hydroxide, 30 parts of soda and 2000 parts of water entered. The dye formed precipitates immediately. The dark purple precipitate is filtered and dried.

PATENTANSPRUCH: Verfahren zur Herstellung eines neuen Farbstoffes, welcher der Formel EMI0001.0020 entspricht, dadurch gekennzeichnet, dass man dianotiertes 4-(1'-Methyl)-phenoxyacetylamino- 2 . 5-dimethogy-l-aminobenzol mit dem m-Ni- tranilid der 2.3-Ogynaphthoesäure kuppelt. Der neue Farbstoff bildet ein dunkel violettes Pulver. Auf geeigneten Substraten, wie zum Beispiel pflanzlichen Fasern, herge- stellt, färbt er diese in echten blauvioletten Tönen. PATENT CLAIM: Process for the production of a new dye, which of the formula EMI0001.0020 corresponds, characterized in that dianotated 4- (1'-methyl) -phenoxyacetylamino-2. 5-dimethogy-l-aminobenzene couples with the m-nitranilide of 2,3-ogynaphthoic acid. The new dye forms a dark purple powder. Produced on suitable substrates, such as vegetable fibers, he dyes them in real blue-violet tones.
