auf nativer oder regenerierter Cellulose mit kupferabgebenden Mitteln behandelt. Hierbei erreicht man eine Verbesserung der Wasser- und Waschechtheiten, was insofern überraschend ist, als die Cellulosefärbung mit diesem Farbstoff (C. I. Direct Black 19 = Benzo Fast Black G) nach den Angaben im Colour Index, 2. Auflage, Bd. 2, S. 2332, in Verbindung mit Bd. 3, Farbstoff Nr. 35 255, angeblich nicht kupferbar ist.Treated on native or regenerated cellulose with copper-releasing agents. Here one achieves an improvement in the water and wash fastness properties, which is surprising as the cellulose dyeing with this dye (C.I. Direct Black 19 = Benzo Fast Black G) according to the information in Color Index, 2nd Edition, Vol. 2, p. 2332, in conjunction with Vol. 3, Dye No. 35,255, allegedly is not copperable.
Der Farbstoff kann auf Cellulosematerialien sowohl als Individuum als auch im Gemisch mit anderen Nuancier- oder Begleitfarbstoffen gefärbt werden. Für die Herstellung schwarzer Farbtöne kommt häufig eine Mehrzahl von Farbstoffen zur Anwendung.The dye can be used on cellulosic materials both individually and in admixture with others Nuance or accompanying dyes are colored. For the production of black shades comes often a plurality of dyes are used.
In solchen Gemischen soll der Anteil des Farbstoffs C. I. Direct Black 19 zumindest zu 20% enthalten sein.In such mixtures, the proportion of the dye C.I. Direct Black 19 should contain at least 20% being.
Die Färbung wird nach an sich üblichen Methoden durchgeführt. Gleiches gilt für die Behandlung mit kupferabgebenden Salzen. Als solche sind z. B. wäßrige Lösungen von Kupfersulfat geeignet.The staining is carried out according to conventional methods. The same applies to treatment with copper-releasing salts. As such are e.g. B. aqueous solutions of copper sulfate are suitable.

wird auf einem Baumwoll- oder Zellwollgewebe nach folgendem Verfahren gefärbt:is dyed on a cotton or cellulose fabric using the following procedure:
Man färbt 100 g Baumwollgarn oder Viskosegarn in einer Färbeflotte von 2 1, die 7 bis 8 g des Farbstoffs, 40 g Glaubersalz oder Duisburger Natriumsulfat und 2 g Soda (nur bei Baumwollfärbungen) enthält. Man beginnt die Färbung bei 4O0C, steigert die Temperatur innerhalb 20 Minuten auf 80 bis 85° C und beläßt das Bad 1 Stunde bei dieser Temperatur. Anschließend wird das Garn zunächst mit 400C warmem und dann mit kaltem Wasser gründ-Hch gespült. Dann wird in einem wäßrigen Bad gekupfert, das in 2 1 3 g Kupfersulfat (CuSO4 · 5H2O) und 4 g 40%ige Essigsäure enthält; man behandelt 20 bis 30 Minuten bei 70 bis 8O0C. Anschließend wird zur Verbesserung der Wasch- und Reibechtheit der gekupferten Färbung mit 0,5 bis 1 g/1 des Natriumsalzes einer Paraffinsulfonsäure oder mit 2 bis 3 g/1 Marseiller Seife bei 45° C geseift, dann kalt gespült und getrocknet.100 g of cotton yarn or viscose yarn are dyed in a dye liquor of 2 liters which contains 7 to 8 g of the dye, 40 g of Glauber's salt or Duisburg sodium sulfate and 2 g of soda (only for cotton dyeings). Staining at 4O 0 C. begins, the temperature increases over 20 minutes at 80 to 85 ° C and leaves the bath for 1 hour at this temperature. Subsequently, the yarn is first warm at 40 0 C and then rinsed with cold water Gründ-Hch. Then it is coppered in an aqueous bath which contains 2 1 3 g of copper sulfate (CuSO 4 · 5H 2 O) and 4 g of 40% acetic acid; treating 20 to 30 minutes at 70 to 8O 0 C. Then, to improve the washing and fastness to rubbing of the gekupferten staining with 0.5 to 1 g / 1 of sodium salt of a paraffin sulfonic acid or of 2 to 3 g / 1 of Marseilles soap at 45 Soaped at ° C, then rinsed with cold water and dried.
