  <B>Zusatzpatent</B> zum Hauptpatent Nr. 163280.    Verfahren zur Herstellung eines neuen     Küpenfarbstoifes.       Es wurde gefunden, dass man einen neuen       Küpenfarbstoff    erhält, wenn man das     5-Chlor-          4.        7-dimetliyl-3-oxythionaplithen    mit dem       2-(p-Dimethylamit)o-)anil    des     1.2-Naphth-          thioindoxyls        kondensiert.     



  Der neue Farbstoff der Formel  
EMI0001.0010     
    stellt ein     brännlichviolettes    Pulver dar, das  sieh in konzentrierter     Schwefelsäure    mit gelb  lichgrüner Farbe löst und Baumwolle aus  grüngelb gefärbter     Küpe    in dunklen Bordeaux  tönen von sehr guten     Echtheiten    färbt.  



  <I>Beispiel:</I>  212,5 Teile     5-Chlor-4.7-dimethyl-3-oxy-          thionaphthen    werden in $000 Teilen Benzol  mit 330 Teilen 2     (p-Dimethylamino-)ariil    des       1.2-Naphththioindoxyla    bei Siedehitze bis  zur beendeten     Kondensation    gerührt. Der ab-    filtrierte und gewaschene     Farbstoff    wird ge  trocknet.



  <B> Additional patent </B> to the main patent No. 163280. Process for the production of a new vat dye. It has been found that a new vat dye is obtained if the 5-chloro-4, 7-dimethyl-3-oxythionaplith is condensed with the 2- (p-dimethylamite) o-) anil of 1,2-naphthioindoxyl.



  The new dye in the formula
EMI0001.0010
    is a brownish-violet powder that dissolves in concentrated sulfuric acid with a yellowish-green color and dyes cotton from a green-yellow vat in dark bordeaux tones of very good fastness properties.



  <I> Example: </I> 212.5 parts of 5-chloro-4,7-dimethyl-3-oxy-thionaphthene are mixed in $ 000 parts of benzene with 330 parts of 2 (p-dimethylamino) aril of 1,2-naphththioindoxyla at boiling temperature up to completed condensation stirred. The dye which has been filtered off and washed is dried.
