  <B>Zusatzpatent</B> zum Hauptpatent Nr.<B>163280.</B>         Verfahren    zur Herstellung eines neuen     Küpenfarbstoifes.       Es wurde gefunden, dass man einen neuen       Küpenfarbstoff    erhält, wenn man das     2-(p-          Dimethylamino-)anil    des     4.7-Dimetbyl-3-oxy-          thionaphthens    mit 2     .1-Naphththioindoxyl     kondensiert.  



  Der neue     Farbstoff    der Formel  
EMI0001.0010     
    stellt ein     rötlichbraunes    Pulver dar, das sich  in konzentrierter Schwefelsäure mit blauer  Farbe löst und Baumwolle aus rotorange  gefärbter     Küpe    in schönen,     gelbstichig    rot  braunen Tönen von sehr guter Chlor-, Wasch-,       Beuch-    und Lichtechtheit färbt.  



  <I>Beispiel:</I>  310 Teile     2-(p-Dimethylamino-)ariil    des  4.     7-Dimethyl-3-oxythionaphthens,    das durch    Einwirkung von     p-Nitrosodimethylanilin    auf       4.7-Dimethyl-3-oxythionaplithen    erhalten  wird und einen Schmelzpunkt von 208   zeigt,  werden mit 200 Teilen 2 .     1-Naphththioindo-          xyl    in 5000 Teilen Alkohol bis zu beendeter  Kondensation gekocht. Dann wird filtriert,  mit Alkohol gewaschen und der     Farbstoff     getrocknet.



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



  The new dye in the formula
EMI0001.0010
    is a reddish-brown powder that dissolves in concentrated sulfuric acid with a blue color and dyes cotton from a red-orange vat in beautiful, yellow-tinged red-brown shades of very good fastness to chlorine, washing, touching and light.



  <I> Example: </I> 310 parts of 2- (p-dimethylamino) ariil of 4. 7-dimethyl-3-oxythionaphthene, which is obtained by the action of p-nitrosodimethylaniline on 4,7-dimethyl-3-oxythionapliths and one Melting point of 208 shows, with 200 parts 2. 1-Naphththioindoxyl boiled in 5000 parts of alcohol until condensation has ended. It is then filtered, washed with alcohol and the dye is dried.
