Description

  

      Zusatzpatent    zum Hauptpatent Nr.<B>165155.</B>    erfahren zur Herstellung eines metallhaltigen     Farbstoffes.       Es wurde gefunden, dass man einen me  tallhaltigen Farbstoff durch Behandeln des       Azofarbstoffes    aus dianotiertem 4 -     Nitro    -     2-          arnino-l-phenol    und     Aeetessigsäureanilid    mit       kobaltabgebenden    Mitteln in alkalischem Me  dium erhalten kann, wenn diese Behandlung  in Gegenwart von Salzen der Weinsäure er  folgt.  



  Der erhaltene     kobalthaltige    Farbstoff stellt  ein gelbes Pulver dar, das aus einer Lösung  in     Nitro-    oder     Acetylzelluloseesterlack    auf  geeigneten Unterlagen lichtechte gelbe Über  züge ergibt.  



  <I>Beispiel:</I>  34,2 Gewichtsteile des Farbstoffes aus  dianotiertem     4-Nitro-2-arnirio-l-phenol    und       Acetessigsäureanilid    werden in 500 Teilen       Wasser        und        13        Teilen        30        %iger        Natronlauge     aufgeschlämmt und bei 40 0 mit einer Kobalt  lösung aus 14,1 Teilen kristallisiertem     Ko-          baltsulfat,    3,75 Teilen Weinsäure,

   40 Teilen       Wasser        und        27        Teilen        30%igerNatronlauge       versetzt. Hierauf wird 1 Stunde auf<B>65-700</B>  und 2 Stunden auf<B>75-80</B> erwärmt, mit       10        %iger        Ameisensäure        neutralisiert,        filtriert,     ausgewaschen und bei mässiger Temperatur  getrocknet.



      Additional patent to main patent no. <B> 165155. </B> for the production of a metal-containing dye. It has been found that a metal-containing dye can be obtained by treating the azo dye from dianotated 4-nitro-2-arnino-1-phenol and acetoacetic anilide with cobalt-donating agents in an alkaline medium if this treatment is carried out in the presence of salts of tartaric acid .



  The cobalt-containing dye obtained is a yellow powder which, from a solution in nitro or acetyl cellulose ester lacquer, gives light-fast yellow coatings on suitable substrates.



  <I> Example: </I> 34.2 parts by weight of the dye from dianotized 4-nitro-2-arnirio-1-phenol and acetoacetic anilide are suspended in 500 parts of water and 13 parts of 30% sodium hydroxide solution and at 40 ° with a cobalt solution of 14.1 parts of crystallized cobalt sulfate, 3.75 parts of tartaric acid,

   40 parts of water and 27 parts of 30% sodium hydroxide solution are added. The mixture is then heated to <B> 65-700 </B> and 2 hours to <B> 75-80 </B>, neutralized with 10% formic acid, filtered, washed out and dried at moderate temperature.
