  Zusatzpatent zum Hauptpatent     Nr.   <B>187691.</B>    Verfahren zur Herstellung eines     Nonoazofarbstoffes.       Es wurde gefunden,     dass    man einen neuen       Azofarbstoff    erhält, wenn man     diazotierten        1-          Aminobeiizol-2-earbonsäLire-methylester    mit       4-Acetylamino-4'-aoetoacetylamino-3.3'-di-          methyl-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>    <B>15,1</B> Teile     1-Aminobenzol-2-carbonsätire-          methylester    werden wie üblich     diazotiert    und  in eine Lösung von<B>83,8</B> Teilen     4-Aoetyl-          amiiio-4'-        acetoacetylamino   <B>- 3.</B>     3'-        dimethyl   <B>-</B>     di.          phenyl,   <B>100</B> Teilen     Natriumhydroxydlösung,     <B>16</B> Teilen Soda und 2000 Teilen Wasser ein-    getragen. Der gebildete Farbstoff fällt sofort  aus. Er wird filtriert und getrocknet.



  Additional patent to main patent no. <B> 187691. </B> Process for the production of a nonoazo dye. It has been found that a new azo dye is obtained if diazotized 1-aminobeiizol-2-carboxylic acid methyl ester is combined with 4-acetylamino-4'-aoetoacetylamino-3.3'-dimethyl-diphenyl. 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> <B> 15.1 </B> parts of 1-aminobenzene-2-carboxylic acid methyl ester are diazotized as usual and converted into a solution of 83.8 parts of 4 -Aoetyl- amiiio-4'- acetoacetylamino <B> - 3. </B> 3'- dimethyl <B> - </B> di. phenyl, <B> 100 </B> parts of sodium hydroxide solution, <B> 16 </B> parts of soda and 2000 parts of water are introduced. The dye formed precipitates immediately. It is filtered and dried.

PATENTANSPRUCH: Verfahren zur Herstellung eines neuen Azofarbstoffes, dadurch gekennzeichnet, dass man diazotierten 1-Aminobenzol-2-earbon- säure-methylester mit 4-Acetylamino-4'-aceto- acetylamino-3.3#-dimethyl-diphenyl vereinigt. Der neue Farbstoff bildet ein gelbes Pulver. Auf der Faser oder andern Substraten her gestellt, färbt er diese in reinen grüDgelben Tönen an. Claim: Process for the production of a new azo dye, characterized in that diazotized 1-aminobenzene-2-earbonic acid methyl ester is combined with 4-acetylamino-4'-aceto-acetylamino-3.3 # -dimethyl-diphenyl. The new dye forms a yellow powder. Produced on the fiber or other substrates, he stains them in pure green-yellow tones.
