      Zusatzpatent    zum     Hauptpatent    Nr. 172735.    Verfahren zur Herstellung eines neuen     Nüpenfarbstof%s.       Es wurde gefunden, dass man einen  neuen     Küpenfarbstoff    erhält, wenn man  4.     6-Dimethyl-5.-        7-dichlor-3-oxythionaphthen     mit dem     2-(p-Dimethylamino)-anil    des     4-Me-          thyl-6-chlor-3-oxythionaphthens    kondensiert.

    Der neue Farbstoff der Formel:  
EMI0001.0010     
         stellt    ein     rotviolettes    Pulver dar, das sich  in konzentrierter Schwefelsäure mit grüner  Farbe löst und Baumwolle aus braungelb  gefärbter     Küpe    in     beuchechten,    reinen Rosa  tönen färbt.  



  <I>Beispiel:</I>  247     Teile    4. 6 -     Dimethyl    - 5 . 7 -     dichlor-          3-oxythionaphthen    und 330,5 Teile     2-(p-          I)imethylamino)-anil    des     4-Methyl-6-chlor-          3-oxythionaphthens    werden mit 4000     Volum-          teilen    Eisessig auf dem Wasserbade erhitzt,    bis die     Kondensation    beendigt ist. Dann wird  filtriert, gewaschen und getrocknet.



      Additional patent to main patent no. 172735. Process for the production of a new nub dye% s. It has been found that a new vat dye is obtained if 4. 6-dimethyl-5.- 7-dichloro-3-oxythionaphthene is mixed with 2- (p-dimethylamino) anil of 4-methyl-6-chloro -3-oxythionaphthene condensed.

    The new dye of the formula:
EMI0001.0010
         is a red-violet powder that dissolves in concentrated sulfuric acid with a green color and dyes cotton from a brown-yellow vat in pure pink tones.



  <I> Example: </I> 247 parts 4. 6 - Dimethyl - 5. 7-dichloro-3-oxythionaphthene and 330.5 parts of 2- (p- I) imethylamino) anil of 4-methyl-6-chloro-3-oxythionaphthene are heated with 4000 parts by volume of glacial acetic acid on a water bath until condensation is finished. It is then filtered, washed and dried.
