  <B>Zusatzpatent</B> zum Hauptpatent Nr.<B>151335.</B>    Verfahren     zur    Herstellung eines neuen     Küpenfarbstoffes.       Es wurde gefunden, dass man einen neuen       Küpenfarbstoff    erhält, wenn man das     p-Di-          methylaminoanil    des     5-Chlor-6-methyl-3-oxy-          thionaphthens    mit     6-Äthoxy#3-oxythionaphthen     kondensiert.  



  Der neue     Farbstoff    der Formel       Cl-/C0ll",        1/        CO1,#"0          CHss-    _<B>Z</B>     -0C2135     S S  stellt ein orangerotes Pulver dar, das Baum  wolle aus gelbgrün gefärbter     Küpe    in roten  'Tönen färbt, die sehr gute Chlor-,     Wasch-          und        Beuchechtheit    zeigen.

           Beispiel:     330 Teile     p-Dimethylaminoariil    des     5-Chlor-          6-methyl-3-oxythionaphthens    und 194 Teile       6-Äthogy-3-oxythionaphthen    werden in 4000    Teilen Alkohol suspendiert und zum Sieden  erhitzt, bis die Kondensation zum Farbstoff  beendet ist. Man filtriert und trocknet.



  <B> Additional patent </B> to main patent no. <B> 151335. </B> Process for the production of a new vat dye. It has been found that a new vat dye is obtained if the p-dimethylaminoanil of 5-chloro-6-methyl-3-oxythionaphthene is condensed with 6-ethoxy # 3-oxythionaphthene.



  The new dye of the formula Cl- / C0ll ", 1 / CO1, #" 0 CHss- _ <B> Z </B> -0C2135 SS is an orange-red powder that dyes cotton from a yellow-green vat in red tones that show very good chlorine, wash and laundry fastness.

           Example: 330 parts of p-dimethylaminoariil of 5-chloro-6-methyl-3-oxythionaphthene and 194 parts of 6-ethogy-3-oxythionaphthene are suspended in 4000 parts of alcohol and heated to the boil until the condensation to the dye has ended. Filter and dry.
