      Zusatzpatent    zum Hauptpatent Nr.<B>196072.</B>    Verfahren zur Herstellung eines neuen     Azofarbstofies.       Es     wurde    gefunden, dass! man     einen        neuen          Azofambstoff        erhält;        wenn    man     diazotiertes          1-Amino-2',-nitro-4-olilorbenzol        mit    dem     Ary-          lid,    das     erhalten,        wind    durch     Kondenssi;

  e-          ren    von     5-Aflnino-6-methogy-2-(4'-methogy)-          phenyl-pseudo-azimmdo#ben;za1        mit        Acetesssg-          es@ter,        vereinigt.     



       Der    nee 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>       1.7,2I        Teile        1-Amino-2i-nitro-4-chlorbenzol     werden wie üblich     diazotiert    und in     eine     Lösung von     3i5;

  5        Teilen    des Konden  sationsproduktes, aus     ,5-Amino-,6-methogy-2-          (4'        -i        methogy)i-phenyll-pseudo-        azimidobenzol     mit     Acetessgester,    100     Teilen    Natrium-         hydrogydlöeung    von 3!6       B6,    15 Teilen       Natriumacetat    und 2000 Teilen Wasser ein  getragen.

   Der     gebildete    gelbe Farbstoff fällt       sofort        aus,.    Er     wird        filtriert    und getrocknet.



      Additional patent to main patent no. <B> 196072. </B> Process for the production of a new azo dye. It was found that! a new azo fiber is obtained; if you diazotized 1-amino-2 ', - nitro-4-olilorbenzene with the arylide that is obtained, through condensation;

  e- ren of 5-aflnino-6-methogy-2- (4'-methogy) -phenyl-pseudo-azimmdo # ben; za1 with Acetesssg es @ ter, combined.



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



  <I> Example: </I> 1.7.2I parts of 1-amino-2i-nitro-4-chlorobenzene are diazotized as usual and dissolved in a solution of 3i5;

  5 parts of the condensation product from, 5-amino-, 6-methogy-2- (4 '-i methogy) i-phenyl-pseudo-azimidobenzene with acetessgester, 100 parts of sodium hydrogyd solution of 3! 6 B6, 15 parts of sodium acetate and 2000 parts of water.

   The yellow dye formed precipitates immediately. It is filtered and dried.
