Description
<B>Zusatzpatent</B> zum Hauptpatent Nr. 141535. Verfahren zur Herstellung eines metallhaltigen Farbstoffe. Es wurde gefunden, dass man einen neuen metallhaltigen Farbstoff erhält, wenn man den Farbstoff aus dianotiertem 4-Chlor-2-amino-l- phenol und f-Naphthol mit der Suspension einer Verbindung des dreiwertigen Eisens behandelt.
Der gebildeteFarbstoff bildet ein tiefbraun gefärbtes Pulver, das in Wasser und Natron lauge sehr schwer löslich ist; in konzentrierter Schwefelsäure löst es sich mit rotvioletter Farbe. Aus der tiefbraun gefärbten Lösung in Zaponlack erhält man auf Metallfolien braunschwarze Überzüge von sehr guter Licht echtheit.
<I>Beispiel:</I> 5,97 Gewichtsteile des Farbstoffes aus dianotiertem 4-Chlor-2-amino-l-phenol und ss-Naphthol werden in 500 Teilen Wasser auf gekocht und mit einer 1,2 Teilen Eisen ent sprechenden Menge einer frisch gefällten und neutral gewaschenen Ferrihydroxydsuspension einige Zeit am Rückflusskühler zum Sieden erhitzt. Nach dem Erkalten wird der abge schiedene Farbstoff abfiltriert, ausgewaschen und bei mässiger Temperatur getrocknet.
<B> Additional patent </B> to main patent no. 141535. Process for the production of a metal-containing dye. It has been found that a new metal-containing dye is obtained if the dye composed of dianotized 4-chloro-2-amino-1-phenol and f-naphthol is treated with a suspension of a trivalent iron compound.
The dye formed forms a deep brown colored powder which is very sparingly soluble in water and sodium hydroxide solution; in concentrated sulfuric acid it dissolves with a red-violet color. From the deep brown colored solution in zapon lacquer, brown-black coatings of very good lightfastness are obtained on metal foils.
<I> Example: </I> 5.97 parts by weight of the dye from dianotized 4-chloro-2-amino-1-phenol and ß-naphthol are boiled in 500 parts of water and mixed with a corresponding amount of 1.2 parts of iron a freshly precipitated and neutral washed ferric hydroxide suspension heated to boiling for some time on the reflux condenser. After cooling, the deposited dye is filtered off, washed and dried at a moderate temperature.
