      Zusatzpatent    zum Hauptpatent Nr. 103649.    Verfahren zur Herstellung eines     indigoiden        Farbstoffes    der     Anthracenreihe.       Es wurde - gefunden, dass man einen     in-          digoiden    Farbstoff der     Anthracenreihe    erhält,  wenn man ein     Anil    des     2,3-Anthrachinon-          thioisatins    mit     1-Oxyanthrmen        kondensiert.     Der Farbstoff bildet ein schwarzviolettes  Pulver, das sich in Schwefelsäure mit grüner  Farbe löst und eine olivenbraune     Küpe    gibt,

    aus welcher Baumwolle grau gefärbt wird.         Beispiel     20,5 Teile des     p-Dimetliylaminoanils    des       2,3-Antlirachinonthioisatins    werden - mit 10  Teilen     1-Oxyanthracen    und 500 Teilen       Pyridin    oder     Trichlorbenzol    zwei Stunden  unter     R.ückfluss    gekocht. Der ausgeschiedene  Farbstoff wird abgesaugt, gewaschen und  getrocknet.  



  Die Reaktion verläuft. nach folgender  Gleichung  
EMI0001.0021     




      Additional patent to main patent no. 103649. Process for the production of an indigoid dye of the anthracene series. It has been found that an indigo dye of the anthracene series is obtained if an anil of 2,3-anthraquinone thioisatin is condensed with 1-oxyanthrm. The dye forms a black-violet powder that dissolves in sulfuric acid with a green color and gives an olive-brown vat,

    which cotton is dyed gray. EXAMPLE 20.5 parts of the p-dimethylaminoanil of 2,3-antlirachinonthioisatins are refluxed for two hours with 10 parts of 1-oxyanthracene and 500 parts of pyridine or trichlorobenzene. The precipitated dye is filtered off, washed and dried.



  The reaction proceeds. according to the following equation
EMI0001.0021
