Description
6 Teile des in üblicher Weise durch Kuppeln der Diazoverbindungen aus 30 Teilen 2-Naphthylamin-3 ·6-disulfosäure mit 31 Teilen 2-Naphthol-3 · 6-disulfosäure in alkalischer Lösung hergestellten Monoazofarbstoffs werden in Wasser gelöst und diese Lösung unter gutem Rühren zu einer Mischung gegeben, die durch sorgfältiges Anschlemmen von 10 Teilen einer 10 prozentigen Paste von Tonerdehydrat mit Wasser hergestellt worden ist. Zu dem so erhaltenen Gemisch wird darauf eine 5 prozentige Chlorbaryumlösung zugesetzt, bis der Farbstoff vollständig ausgefällt ist. Der Niederschlag wird abfiltriert, ausgewaschen, getrocknet und der Lack in üblicher Weise fertig gemacht. Derselbe zeigt eine schöne rote Nuance und ist in Wasser unlöslich.6 parts of the in the usual way by coupling the diazo compounds from 30 parts 2-naphthylamine-3 · 6-disulfonic acid with 31 parts of 2-naphthol-3 · 6-disulfonic acid in alkaline Solution prepared monoazo dye are dissolved in water and this solution under added good stirring to a mixture obtained by carefully pinching together 10 parts of a 10 percent paste of Alumina hydrate has been made with water. The mixture thus obtained becomes then a 5 percent chlorobaryum solution was added until the dye completely precipitated is. The precipitate is filtered off, washed out, dried and the varnish in usually done ready. It shows a nice red shade and is in Water insoluble.
An Stelle des in dem Beispiel beschriebenen Verfahrens kann man selbstverständlich auch andere der in der Pigmentfarbenfabrikation üblichen Lackbildungsmethoden anwenden. Instead of the method described in the example, one can of course also use other paint formation methods customary in pigment paint production.
