      Additional patent, to the main patent no. <B> 195072. </B> Process for the 'production of a new azo dye. It was found that a new azo dye was obtained when diazotized 1-amino-nitrobenzo-1 with the arylide obtained by condensing 5-amino-methoxy-phenyl -pseudo,

  -azim - idobenzol mü, acetoacetic ester, combined.



  The new dye forms a yellow powder that is insoluble in water. On suitable sub-seeds such B. Cotton, if he dyes them in real. yellow tones.



  <I> Example: </I> <B> <I> 13 A </I> </B> Tdle o-nitranil-in will be as usual. , cliazotized and in a solution of 32.4 parts of the condensation product of 5-amino 2- (4 '- methox-y) -phen, yl-pseudo-azi, miclo, benzene- with acetoacetic ester, <B> 10.0 </B> parts sodium hy # c1 oxide solution of <B> 3.6 '</B> B6, <B> 15 </B> parts sodium trium acetate and 20,010 parts water. The colored yellow dye precipitates immediately. It is filtered and dried.
