Es ist besonders vorteilhaft, die so erhaltenen neuen Farbstoffe vor ihrer Verwendung in Färbepräparate überzuführen. Die Verarbeitung zu Färbepräparaten erfolgt auf allgemein bekannte Weise, z.B. durch Mahlen in Gegenwart von Dispergler- und/oder Füllmitteln. Mit den gegebenenfalls im Vakuum oder durch Zerstäuben getrockneten Präparaten kann man, nach Zugabe von mehr oder weniger Wasser, in sogenannter langer oder kurzer Flotte färben, klotzen oder bedrucken.It is particularly advantageous to use the new dyes thus obtained to be converted into dye preparations before use.
