  Verfahren zur Herstellung eines     Azofarbstoffes.       Vorliegendes Patent bezieht sieh auf ein  Verfahren zur Herstellung eines     Azofarbstof-          fes,    dadurch     "o,ekennzeiohnet,    dass man die       Diazoverbindung    von     3-Chlor-4-aminophenyl-          sulfoylacetdiogyäthylamid    der     Formel:

       
EMI0001.0009     
    mit     Ogäthyl-methyl-m-toluidin        vereinigt.     Der so     erhaltene    Farbstoff färbt, wenn  mit einem     Dispergiermittel    vereinigt, aus  neutralem     Glaubersalzbad    ohne Seifenzusatz       Acetseide    in lebhaften     Scharlachtönen    von       ,guten        Nassechtheiten    und     guter    Lichtecht  heit.  



  <I>Beispiel:</I>  Die aus 33,5 Teilen     3-Chlor-4-amino-          phenylsulfoylaeetogäthylami,d    wie üblich       hergestellte        Diazolösung    wird mit einer salz  sauren     Lösung    von 16,5 Teilen     Ogäthyl-          methyl-m-toluidin    vereinigt. Der     entstandene     Farbstoff wird nach Zugabe von Natrium-         acetat    abgeschieden und mit einem     Disper-          gierungsmittel        verarbeitet.  



  Process for the preparation of an azo dye. The present patent relates to a process for the preparation of an azo dye, characterized in that the diazo compound of 3-chloro-4-aminophenylsulfoylacetdiogyäthylamid of the formula:

       
EMI0001.0009
    combined with Ogäthyl-methyl-m-toluidine. The dye obtained in this way, when combined with a dispersant, dyes from a neutral Glauber's salt bath without added soap, acetone silk in vivid scarlet shades of good wet fastness and good lightfastness.



  <I> Example: </I> The diazo solution prepared as usual from 33.5 parts of 3-chloro-4-aminophenylsulfoylaeetogäthylami, d is combined with a hydrochloric acid solution of 16.5 parts of Ogäthylmethyl-m-toluidine. The resulting dye is deposited after the addition of sodium acetate and processed with a dispersing agent.
