      Zusatzpatent    zum     Hauptpatent    Nr. 195072.    Verfahren zur Herstellung eines neuen     Azofarbstoffes.       Es wurde     gefunden,        dass    man     einen    neuen       Azofarbstoff        erhält,    wenn man     dianotiertes          1-Amio-2@-nitrobenzol    mit :

  dem     Arylid,    das       erhalten        wird        idurch        Kondensieren    von  5     -Amin    o-     6@-methogy-        21..,(4'-methogy)-phenyl-          pseudo-azimidobenzol    mit     Acetessigester,        ver-          einigt.     



  Dar     nenne    Farbstoff bildet     ein        gelbes,    in  Wasser     unlösliches    Pulver. Auf geeigneten  Substraten, wie z. B. Baumwolle,     hergestellt,     färbt     er        idiese        in        echten:        gelben:    Tönen.

      <I>Beispiel:</I>       1,3., &         Teile        o-Nitranilin    werden     wie    üblich       dianotiert    und     m    eine     Lösung    von     3;5,5        Teilen     ,des     gondensiatiomproduktes,    aus     5-Amino,6-          mehb.oxy-:21-(4'_m;et3i,o@xy)        -pIlenyl-pseudo-azi:-          mdobenzol        mit        Acetossigester;

D!er        gebildete    gelbe     Farbstoff          fällt        sofort    aus.     Er    wird filtriert und     ge-          trocknet.  



      Additional patent to main patent no. 195072. Process for the production of a new azo dye. It has been found that a new azo dye is obtained if dianotated 1-Amio-2 @ -nitrobenzene is used with:

  the arylide which is obtained by condensing 5-amine o- 6 @ -methogy- 21 .., (4'-methogy) -phenyl-pseudo-azimidobenzene with acetoacetic ester.



  The dye forms a yellow, water-insoluble powder. On suitable substrates, such as. B. Cotton, produced, he dyes them in real: yellow: tones.

      <I> Example: </I> 1,3., & Parts of o-nitroaniline are dianotized as usual and a solution of 3; 5.5 parts, of the condensation product, of 5-amino, 6- mehb.oxy-: 21- (4'_m; et3i, o @ xy) -pIlenyl-pseudo-azi: - mdobenzene with acetosigester;

     <B> 100 </B> parts of sodium hydrogen solution of <B> 36 </B> B6, <B> 15 </B> parts of sodium acetate and 2,000 parts of water are added. The yellow dye formed precipitates immediately. It is filtered and dried.
