      Zusatzpatent    zum Hauptpatent Nr. 214908.    Verfahren zur Darstellung eines     Nüpenfarbstoffes.       Gegenstand dieses Patentes ist ein Verfah  ren zur     Herstellung    eines     güpenfarbstoffes,     der pflanzliche Fasern in     rotstichig    braunen    Tönen anfärbt. Das Verfahren zu seiner Her  stellung besteht darin, dass man das     Anthri--          mid    der nachstehenden Formel  
EMI0001.0008     
    mit sauren     Kondensationsmitteln    behandelt.

    Der Farbstoff bildet ein dunkelbraunes  Pulver, dessen rotbraune     Hydrosulfitküpe    zur  pflanzlichen Faser grosse Affinität hat und  letztere in sehr echten, klaren,     rotstichig     braunen Tönen färbt.    <I>Beispiel:</I>  9 Gewichtsteile     5.5'-Diamino-1.1'-di-          anthrimidcarbozol,    16     Gewichtsteile    4' .     6'-          Dichloranthrachinon    - 2. 1-N-1' . 2'-N -     benz-          acridon,    3 Gewichtsteile Pottasche, 0,5 Ge  wichtsteile Kupferacetat und 200 Gewichts-      teile Naphthalin werden 10 Stunden auf  210' C unter Rühren erhitzt.

   Dann wird mit  Chlorbenzol verdünnt, heiss abgesaugt und in  üblicher Weise abgesaugt und getrocknet.  Zur Kondensation werden 21     Gewichtsteile     des     Trianthrimides    in eine Lösung von 70 Ge-         wichtsteilen    Aluminiumchlorid und 210 Ge  wichtsteilen Nitrobenzol eingetragen und  Stunden auf 90 " C erhitzt, worauf die Lö  sungsfarbe von oliv nach grünblau umge  schlagen ist. Das Nitrobenzol wird mit Was  serdampf abgetrieben, der Farbstoff, der die  nachstehende Konstitution besitzt  
EMI0002.0004     
    in üblicher Weise isoliert,     fein    verteilt, mit.  alkalischer Chlorlauge oxydiert, um ihn zu  schönen, abgesaugt, gewaschen und getrock  net.

   Er bildet ein dunkelbraunes Pulver, des  sen rotbraune     Hydrosulfitküpe    zur pflanz  lichen Faser grosse Affinität hat und letztere    in sehr echten, klaren     rotstiehig    braunen  Tönen färbt.



      Additional patent to main patent no. 214908. Process for the preparation of a pebble dye. The subject of this patent is a process for the production of a güpen dye that dyes vegetable fibers in reddish brown tones. The process for making it is by taking the anthrimide of the formula below
EMI0001.0008
    treated with acidic condensing agents.

    The dye forms a dark brown powder, the red-brown hydrosulphite vat of which has a great affinity for the vegetable fiber and colors the latter in very genuine, clear, reddish brown tones. <I> Example: </I> 9 parts by weight of 5.5'-diamino-1.1'-di-anthrimidecarbozole, 16 parts by weight of 4 '. 6'-dichloroanthraquinone - 2. 1-N-1 '. 2'-N-benz-acridone, 3 parts by weight of potash, 0.5 parts by weight of copper acetate and 200 parts by weight of naphthalene are heated to 210 ° C. for 10 hours while stirring.

   It is then diluted with chlorobenzene, filtered off with suction while hot and suctioned off and dried in the usual way. For condensation, 21 parts by weight of the trianthrimide are added to a solution of 70 parts by weight of aluminum chloride and 210 parts by weight of nitrobenzene and heated to 90 ° C. for hours, whereupon the solution color has changed from olive to green-blue. The nitrobenzene is driven off with water vapor, the dye which has the following constitution
EMI0002.0004
    isolated in the usual way, finely divided, with. alkaline chlorine hydroxide is oxidized in order to make it beautiful, suctioned off, washed and dried.

   It forms a dark brown powder, the reddish brown hydrosulphite vat of which has a great affinity for the vegetable fiber and colors the latter in very genuine, clear reddish brown tones.
