  <B>Zusatzpatent</B> zum Hauptpatent Nr. 163280.    Verfahren zur Herstellung eines neuen     Nüpenfarbstoffes.       Es wurde gefunden, dass man einen neuen       Küpenfarbstoff    erhält, wenn man das     2-(p-          Din)ethylainino-)anil    des 4.     7-Diniethyl-3-oxy-          thionaplithens    mit     1-Chlor-2        .3-najihtlitliiö-          indoxyl    kondensiert.  



  Der neue     Farbstoff    der Formel .  
EMI0001.0011     
    stellt ein rotviolettes Pulver dar, das sich in  konzentrierter Schwefelsäure mit     hellgrüner     Farbe löst und Baumwolle aus     orangebraun     gefärbter     Küpe    in rotvioletten Tönen von  sehr guten     Echtheitseigenschaften    färbt.  



  <I>Beispiel:</I>  310 Teile     2-(p-Dimethylamirio-)ariil    des       4.7-Dimethyl-3-oxythionaplithens    werden mit  235 Teilen     1-Clilor-2.        3-naphththioiridoxyl    in  6000 Teilen Alkohol gekocht, bis die Kon  densation beendet ist. Dann wird filtriert,    mit Alkohol gewaschen und der     Farbstoff     getrocknet.



  <B> Additional patent </B> to the main patent No. 163280. Process for the production of a new pimple dye. It has been found that a new vat dye is obtained if the 2- (p-din) ethylainino-) anil of 4, 7-diniethyl-3-oxythionaplithene is condensed with 1-chloro-2 .3-najihtlitliiö- indoxyl .



  The new dye in the formula.
EMI0001.0011
    is a red-violet powder that dissolves in concentrated sulfuric acid with a light green color and dyes cotton from an orange-brown vat in red-violet shades with very good fastness properties.



  <I> Example: </I> 310 parts of 2- (p-dimethylamirio-) aril of 4,7-dimethyl-3-oxythionaplithene are mixed with 235 parts of 1-Clilor-2. 3-naphththioiridoxyl boiled in 6000 parts of alcohol until the condensation has ended. It is then filtered, washed with alcohol and the dye is dried.
