  <B>Zusatzpatent</B> zum Hauptpatent Nr. 195072.    Verfahren zur Herstellung eines neuen     Azofarbstoües.       Es wurde gefunden,     @da3    man einen neuen       Azofarbstoff        erhält,    wenn man     diazoniertes          1-Amino-2t-nätro-4-.methogybenzol        mit        dem          Arylid,    das     erhalten;

      wird     @durch    Konden  sieren von     5-Ami.no-2-(4'-äthogy)-phenyl-          pseudo=azimidobenzo.1    mit     Aoetessigester,        ver-          einigt.     



  Der neue     Farbstoff        .bildet        eingelbes,    in       Wasser        unlösliches    Pulver. Auf geeigneten       Substraten,    wie z. B. Baumwolle,     hergestellt,     färbt er     ,diese    in     echten    gelben Tönen.

      <I>Beispiel:</I>         16.,8    Teile     1-Amino@-2-nitro-4-methogy-          benzol    werden     wieg    üblich     diazotiert    und in       eine        Lösung    von     3,3,8    Teilen     des    Konden  sationsproduktes aus     5-Amino-2-(4'-äthogy)-          ph.enyl-pseudo-azimvdobenzol    mit     Acetessig-          ester,

  <B> Additional patent </B> 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 diazonated 1-amino-2t-nätro-4-methogybenzene is obtained with the arylide that;

      is combined by condensing 5-Ami.no-2- (4'-ethogy) -phenyl-pseudo = azimidobenzo.1 with aoetoacetic ester.



  The new dye forms a yellow powder that is insoluble in water. On suitable substrates, such as. B. Cotton, produced, he dyes these in real yellow tones.

      <I> Example: </I> 16., 8 parts of 1-amino @ -2-nitro-4-methogybenzene are diazotized as usual and converted into a solution of 3.3.8 parts of the condensation product of 5-amino -2- (4'-ethogy) - ph.enyl-pseudo-azimvdobenzene with acetoacetic ester,

          1001 parts of sodium hydroxide solution of. 316 'B6, 1.5 parts of sodium acetate and 2.0.00 parts of water entered. The yellow dye formed precipitates immediately.

   He wind filtered and @dried.
