  Zusatzpatent zum Hauptpatent     Nr.   <B>163280.</B>    Verfahren zur Herstellung eines neuen     Klipenfarbstoffes.       Es wurde gefunden,     dass        inan    einen neuen       Küpenfarbstoff        ei-hält,    wenn man das     5-Chlor-          4.        7-dimethyl-3-oxythiotiaphtheii    mit dem     2-(p-          Dimethylamino-)anil    des     5-Chlor-7-inethyl-3-          oxythioiiaphthens    kondensiert.  



  Der neue Farbstoff der Formel  
EMI0001.0014     
    stellt ein blaustichig rotes Pulver dar, das  sich in konzentrierter Schwefelsäure mit  grüner Farbe löst und Baumwolle aus grün  gelb gefärbter     Küpe    in rotvioletten Tönen  von hervorragender Echtheit färbt.  



  <I>Beispiel:</I>  <B>212,5</B> Teile     5-Chlor-4.        7-dimetliyl-3-oxy-          thionaplithen    werden in<B>8800</B> Teilen Benzol  mit<B>330,5</B> Teilen     2-(p-Dimethylamino-)anil     des     5-Chloi,-7-methyl-3-oxythioriaphthens    bei  etwa<B>80 0</B> verrührt, bis die Kondensation    beendet ist. Der Farbstoff wird hierauf     ab-          filtriert,    gewaschen und getrocknet.



  Additional patent to main patent no. <B> 163280. </B> Process for the production of a new clip dye. It has been found that a new vat dye holds inan if the 5-chloro-4, 7-dimethyl-3-oxythiotiaphtheii with the 2- (p-dimethylamino) anil des 5-chloro-7-ynethyl-3 - oxythioiiaphthens condensed.



  The new dye in the formula
EMI0001.0014
    is a bluish red powder that dissolves in concentrated sulfuric acid with a green color and dyes cotton from a green-yellow vat in red-violet shades of excellent fastness.



  <I> Example: </I> <B> 212.5 </B> parts 5-chloro-4. 7-dimethyl-3-oxy-thionaplithen are mixed in <B> 8800 </B> parts of benzene with <B> 330.5 </B> parts of 2- (p-dimethylamino-) anil des 5-chloro, -7- methyl-3-oxythioriaphthens is stirred at about 80 ° until the condensation has ended. The dye is then filtered off, washed and dried.
