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.
