  Verfahren zur Herstellung eines     blonoazofarbstoffes.       Gegenstand     ,des    vorliegenden     Zusatzpatent-          Herstellung          gesuelies    ist ein Verfahren zur Herstellung  eines     Monoazofarbstoffes,        ,dadurch    gekenn  zeichnet, dass man die     Diazoverbindung    der  2-     (4'-Aminophenyl)-,6-methylbenzothiazol-7-          sulfonsäure    mit 2 -     (-4'-        Acetoa@cetylamino-          phenyl)    - 6     -methylbenzothiazol-3'-sulfonsäure     kuppelt.

   Der erhaltene Farbstoff färbt  Baumwolle und Viskose in     grünstichig    gel  ben Tönen von ehr guter     Wasser-        und     Waschechtheit sowie sehr guter Lichtecht  heit.  



  <I>Beispiel:</I>  320 Gewichtsteile     2-(4'-Amiuophenyl)=6-          methylbenzothiazol-7-sulfoneäure    werden wie  üblich     diazotiert    und mit 404     Gewichtsteilen     2 -     (4'-        Acetoacetylaminophenyl)-6-methylben-          zothiazol-3'-sulfonsäure    in     sodaalkalischer     Lösung gekuppelt. Der erhaltene     Farbstoff       färbt Baumwolle und Viskose in     grünstichig          ,gelben    Tönen von sehr .guter Wasser-     und          Waschechtheit    sowie :guter Lichtechtheit.



  Process for the preparation of a blonoazo dye. The subject of the present additional patent production is a process for the production of a monoazo dye, characterized in that the diazo compound of 2- (4'-aminophenyl) -, 6-methylbenzothiazole-7-sulfonic acid with 2 - (-4 ' - Acetoa @ cetylaminophenyl) - 6 -methylbenzothiazole-3'-sulfonic acid couples.

   The dye obtained dyes cotton and viscose in greenish yellow shades of good water and wash fastness and very good light fastness.



  <I> Example: </I> 320 parts by weight of 2- (4'-amiuophenyl) = 6- methylbenzothiazole-7-sulfonic acid are diazotized as usual and with 404 parts by weight of 2- (4'-acetoacetylaminophenyl) -6-methylbenzothiazole- 3'-sulfonic acid coupled in a soda-alkaline solution. The dye obtained dyes cotton and viscose in greenish, yellow shades of very good water and wash fastness and: good light fastness.
