Description

  

  Verfahren zur Herstellung eines     Honoazofarbstoffes.       Es wurde gefunden, dass man einen neuen       Azofarbstoff    erhält, wenn man     diazotierten        1-          Aminobenzol-2-carbonsäure-äthylester    mit     4-          Acetylamino-4'-        acetoacetylamino    - 3 . 3'-     dime-          thyl-diphenyl    vereinigt. Der neue Farbstoff  bildet ein gelbes Pulver. Auf der Faser oder  andern Substraten hergestellt, färbt er diese  in reinen grüngelben Tönen an.

      <I>Beispiel:</I>    16,5 Teile     1-Aminobenzol-2-carbonsäure-          äthylester    werden wie üblich     diazotiert    und  in eine Lösung von 33,8 Teilen     4-Acetyl-          amino-4'-        acetoacetylamino.3    . 3'-     dimethyl        -di-          phenyl,    100 Teilen     Natriumhydrogydlösung,     15 Teilen Soda und 2000 Teilen Wasser ein-    getragen. Der gebildete Farbstoff fällt sofort  aus. Er wird filtriert und getrocknet.



  Process for the preparation of a honoazo dye. It has been found that a new azo dye is obtained if diazotized 1-aminobenzene-2-carboxylic acid ethyl ester with 4-acetylamino-4'-acetoacetylamino-3. 3'-dimethyl-diphenyl combined. The new dye forms a yellow powder. Produced on the fiber or other substrates, he stains them in pure green-yellow tones.

      <I> Example: </I> 16.5 parts of 1-aminobenzene-2-carboxylic acid ethyl ester are diazotized as usual and converted into a solution of 33.8 parts of 4-acetylamino-4'-acetoacetylamino. 3. 3'-dimethyldiphenyl, 100 parts of sodium hydrogen solution, 15 parts of soda and 2000 parts of water are introduced. The dye formed precipitates immediately. It is filtered and dried.
