  Verfahren zur Darstellung eines     Monoazofarbstoffes.       Es wurde gefunden,     dass    man einen wert  vollen     Monoazofarbstoff    erhält, wenn man  die     Diazoverbii   <B>'</B>     idung    des     5-Nitro-2-amirio-          benzol-l-earboiisäLiremethyl,itriilids    -mit der     2-          Methylaminonaphtaliii-7-stilfosäure    in saurer  Kupplung vereinigt.  



  Das neue Produkt färbt Wolle in saurem  Bade in rotvioletten Tönen an. Es zeigt  neben guter     Walk-        und    Lichtechtheit ein  gutes     Egalisierungsvermögen.     



  <I>Beispiel:</I>  <B>271</B>     Gewichtsteile        5-Nitro-2-amiiiobenzol-          1-carbonsäuremethylanilid    (Schmelzpunkt<B>183</B>  bis.     184')    werden     diazotiert    und bei Gegen  wart von     Natriumacetat    mit<B>237</B> Gewichts  teilen     2-Methylarninoiiaphtalin-7-stilfosä#ire     vereinigt. Nach beendigter Kupplung wird  der Farbstoff     ausgesalzen    und wie üblich    aufgearbeitet.

   Er färbt Wolle in     rotvioletten.     Tönen an, die sich durch gutes     Egalisierungs-          vermögen,        Walk-    und     Lichteobtu'eif    au     s-          zeichnen.  



  Process for the preparation of a monoazo dye. It has been found that a valuable monoazo dye is obtained if the diazoverbii <B> '</B> idung of 5-nitro-2-amirio-benzene-l-earboiisäLiremethyl, itriilids -with the 2- methylaminonaphtaliii-7- stilfosäure combined in acid coupling.



  The new product dyes wool in an acid bath in red-violet tones. In addition to good fullness and lightfastness, it shows good leveling properties.



  <I> Example: </I> <B> 271 </B> parts by weight of 5-nitro-2-amiobenzene-1-carboxylic acid methyl anilide (melting point 183 to 184 ') are diazotized and, if present, of sodium acetate with <B> 237 </B> parts by weight 2-Methylarninoiiaphtalin-7-stilfosä # ire combined. When the coupling is complete, the dye is salted out and worked up as usual.

   He dyes wool in reddish-purple. Tones that are characterized by good equalization, fulling and light obtu'eif.
