      Zusatzpatent    zum Hauptpatent     Nr.    172735.    Verfahren zur Herstellung eines neuen     Küpenfarbstoffes.       Es wurde gefunden, dass man einen  neuen     Küpenfarbstoff    erhält, wenn man  4 .     6-Dimethyl-5    .     7-dichlor-3-oxythionaphthen          finit    dem     2-(p-Dimethylamino)-anil    des 4. 7  Dimethyl-5-chlor=3-oxythionaphthens konden  siert.  



  Der neue Farbstoff der Formel:  
EMI0001.0009     
    stellt ein rotes Pulver dar, das sich in kon  zentrierter Schwefelsäure mit grüner Farbe  löst und Baumwolle aus gelb gefärbter     Küpe     in     beuchechten,    sehr reinen,     rotvioletten    Tö  nen färbt.  



  <I>Beispiel:</I>  247 Teile 4.     6-Dhmathyl-5.        i7-diehlor-3-          oxythionaphthen    und 344,5 Teile     2-(p-Di-          inethyjamino)-anil    des     4.7-Dimethyl-5-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 vat dye. It has been found that a new vat dye is obtained if 4. 6-dimethyl-5. 7-dichloro-3-oxythionaphthene finely condensed with the 2- (p-dimethylamino) -anil des 4. 7-dimethyl-5-chloro = 3-oxythionaphthene.



  The new dye of the formula:
EMI0001.0009
    is a red powder that dissolves in concentrated sulfuric acid with a green color and dyes cotton from a yellow vat in dark, very pure, red-violet tones.



  <I> Example: </I> 247 parts 4. 6-Dhmathyl-5. i7-diehlor-3-oxythionaphthen and 344.5 parts of 2- (p-di-inethyjamino) -anil des 4,7-dimethyl-5-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.
