  Zusatzpatent zum Hauptpatent     Nr.   <B>172735.</B>    Verfahren zur Herstellung eines neuen     Küpenfarbstoffes.       Es wurde gefunden,     dass    man einen  neuen     Küpenfarbstoff    erhält, wenn man  4.     6-Dimethyl-5.        7-dibrom-3-oxythionaplithen     mit dem     2-(p-Dimethylamino-)-anil    des     5-          Chl(>r-7-methyl-3-oxythionaphi-hens        kondeyl-          siert.     



  Der neue Farbstoff der Formel.  
EMI0001.0012     
    stellt ein     rotviolettes    Pulver dar, das sich  in konzentrierter Schwefelsäure mit grüner  Farbe löst und Baumwolle aus grüngelb  gefärbter     Küpe    in     beuehechten,    reinen, vio  letten Tönen färbt.  



  <I>Beispiel:</I>  <B>336</B> Teile     4.6-Dimethyl-5.7-dibrom-          3-oxythiona,phthen    und<B>330,5</B> Teile     2-(p-          Dimethy,lamino)-anil    des     5-Chlor-7-metliyl-          3-oxythionaplithens    werden mit 4000     Volum-          teilen    Eisessig auf dem Wasserbade erhitzt,    bis die Kondensation beendigt ist. Dann wird  filtriert,     gewaselien    und     getroaknet.  



  Additional patent to main patent no. <B> 172735. </B> 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-dibromo-3-oxythionaplithen condensed with 2- (p-dimethylamino-) - anil des 5-Chl (> r-7-methyl-3-oxythionaphi-hens.



  The new dye in the formula.
EMI0001.0012
    is a red-violet powder that dissolves in concentrated sulfuric acid with a green color and dyes cotton from a green-yellow vat in blue, pure, violet tones.



  <I> Example: </I> <B> 336 </B> parts 4.6-dimethyl-5.7-dibromo-3-oxythiona, phthene and <B> 330.5 </B> parts 2- (p-dimethy, lamino) -anil of 5-chloro-7-methyl-3-oxythionaplithene are heated with 4000 parts by volume of glacial acetic acid in a water bath until the condensation has ended. Then it is filtered, washed and dried.
