  <B>Zusatzpatent</B>     zum        Hauptpatent    Nr. 220222.    Verfahren zur     Herstellung    eines     Nüpenfarbstoffes.            Gegenstand    des vorliegenden     Zusatzfpa-          tentes    ist ein Verfahren zur Herstellung eines       Küpenfarbstoffes,    welches     idadurch    gekenn  zeichnet ist,

   dass man     6-Methoxy-4-trifluor-          methyl-3-oxythionaphthen    mit einem     re-          iktionsfähigen        2-Derivat    des     4-Methyl-6-          chlor-    2 . 3 -     diketodihydrothionaph        tenahinons     kondensiert. Der gebildete     güpenfarbstoff     färbt Baumwolle in sehr klaren scharlach-         roten    Tönen von     guten    bis sehr     guten        Echt-          heitseigenschaften.     



  <I>Beispiel:</I>  12,4     Gewichtsteile        6-Methoxy-4-trifluor-          methyl-3-oxythionap@hthen        werden    in 500 Ge  wichtsteilen Chlorbenzol     mit    16,5     Gewichts-          teilen        4-Methyl-6-chlor-2.3-diketodihydro-          thionaphthenchino:n-2-(p-dimethylamino)-anil     10 Stunden auf 80-90   C erhitzt. Die Um  setzung verläuft nach folgendem Schema.:

  <B> Additional patent </B> to main patent no. 220222. Process for the production of a pebble dye. The subject of the present additional patent is a process for the production of a vat dye, which is characterized by

   that 6-methoxy-4-trifluoromethyl-3-oxythionaphthene with a reactive 2-derivative of 4-methyl-6-chloro-2. 3 - diketodihydrothionaph tenahinons condensed. The güpen dye formed dyes cotton in very clear, scarlet-red tones with good to very good fastness properties.



  <I> Example: </I> 12.4 parts by weight of 6-methoxy-4-trifluoromethyl-3-oxythionaphthene are added to 500 parts by weight of chlorobenzene with 16.5 parts by weight of 4-methyl-6-chloro-2.3 -diketodihydro- thionaphthenchino: n-2- (p-dimethylamino) -anil heated to 80-90 ° C. for 10 hours. The implementation proceeds according to the following scheme:
