  <B>Zusatzpatent</B> zum Hauptpatent Nr. 186548.    Verfahren zur Herstellung eines     Umwandlungsproduktes    eines komplex  gebundenes Metall enthaltenden Farbstoffes.    Es wurde gefunden, dass man ein Umwand  lungsprodukt eines komplex gebundenes Me  tall enthaltenden Farbstoffes herstellen kann,  wenn man die     Kobaltverbindung    des     Azo-          farbstoffes    der Formel .  
EMI0001.0005     
    auf den Farbstoff der Formel  
EMI0001.0006     
    einwirken lässt,    Das     Umwandlungsprodukt    stellt ein grün  schwarzes Pulver dar, das sich in konzen  trierter Schwefelsäure mit     gelboranger    und  in Alkohol mit     gelbstichig    grüner Farbe löst.

    Aus einer Lösung in einem handelsüblichen       Nitrozelluloselack    erhält man auf geeigneten  Unterlagen echte     gelbstichig    grüne Überzüge.  <I>Beispiel: -</I>  20 Teile der     gobaltverbindung    des Farb  stoffes aus     diazotiertem        4-Nitro-2-amino-l-          phenol    und     Acetessigsäureanilid,    hergestellt  nach dem Verfahren der franz. Patentschrift  758264, werden in 1000 Teilen Wasser  aufgekocht und mit einer Lösung von 10  Teilen     Brillantfirnbla    u (Schultz,     Farbatoff-          tabellen,    7. Auflage, Nr. 762) in 500 Teilen  Wasser versetzt.

   Der neue Farbstoff fällt  in kristalliner Form wasserunlöslich aus und  wird nach einigem Kochen     abfiltriert    und  ausgewaschen.



  <B> Additional patent </B> to main patent No. 186548. Process for the preparation of a conversion product of a dye containing complexed metal. It has been found that a conversion product of a complex-bonded metal-containing dye can be produced if the cobalt compound of the azo dye of the formula.
EMI0001.0005
    on the dye of the formula
EMI0001.0006
    The conversion product is a green-black powder that dissolves in concentrated sulfuric acid with a yellow-orange color and in alcohol with a yellow-tinged green color.

    A solution in a commercially available nitrocellulose varnish gives real yellowish green coatings on suitable substrates. <I> Example: - </I> 20 parts of the cobalt compound of the dye from diazotized 4-nitro-2-amino-1-phenol and acetoacetic anilide, produced by the process of the French. Patent specification 758264, are boiled in 1000 parts of water and a solution of 10 parts of Brillantfirnbla u (Schultz, Farbatoff tables, 7th edition, No. 762) in 500 parts of water is added.

   The new dye precipitates out in water-insoluble form in crystalline form and is filtered off and washed out after boiling for a while.
