1,5 Teilen komplexer Barium-Cadmium-Stabilisator 0,02 Gewichtsprozent der nach Beispiel 1 hergestellten Präparation gegeben und durch 1 Minute langes Rühren mit einem Schnellrührer gleichmäßig in der Paste verteilt. Man läßt die Mischung danach 2Stunden stehen, rührt nochmals 1 Minute und streicht die Masse anschließend mit etwa 1 mm dicker Schicht auf Papier oder textilem Gewebe auf. Die ausgestrichene Paste wird dann während 5 Minuten bei 160° C im Trockenschrank ausgehärtet. Die erhaltene ίο Färbung ist deutlich farbstärker und weniger stippig als eine vergleichbare, jedoch mit nicht präpariertem Pigment hergestellte Färbung.1.5 parts of complex barium-cadmium stabilizer 0.02 percent by weight of that prepared according to Example 1 Preparation given and by stirring for 1 minute with a high-speed stirrer evenly in the Spread the paste. The mixture is then left for 2 hours stand, stir for another 1 minute and then coat the mass with an approximately 1 mm thick layer on paper or textile fabric. The spread paste is then applied for 5 minutes Cured 160 ° C in a drying cabinet. The ίο color obtained is clearly stronger and less speckled as a comparable coloration, but made with unprepared pigment.
Man arbeitet gemäß Beispiel 1, fällt jedoch zuerst die Kupplungskomponente in der Essigsäure aus und versetzt die Fällung anschließend mit 102,5 Teilen der dort benutzten Copolymerisat-Dispersion und 74,5 Teilen einer wäßrigen, 55gewichtsprozentigen Polyvinylchlorid-Dispersion, die durch Emulsionspolymerisation von Vinylchlorid erhalten wird und die zur Latexstabilisation 10 Gewichtsprozent Nonylphenolglykoläther als nichtionogenes Verteilungsmittel enthält. Es wird eine Pigmentpräparation mit 50 Gewichtsprozent Pigmentfarbstoff erhalten, die sich ausgezeichnet zum Färben von Polyvinylchloridmassen sowie Polyvinylchloridpasten verwenden läßt.The procedure is as in Example 1, but the coupling component in the acetic acid precipitates first and then added 102.5 parts of the copolymer dispersion used there to the precipitation and 74.5 parts of an aqueous, 55 weight percent polyvinyl chloride dispersion, which by emulsion polymerization is obtained from vinyl chloride and the latex stabilization 10 weight percent nonylphenol glycol ether contains as a nonionic distribution agent.
