Abstract

Abstract Translated from German Verfahren zur Herstellung von Pigmentlegierungen, dadurch gekennzeichnet. dass man eine Mischung, bestehend aus mindestens zwei Pigmenten verschiedener Gruppen der Perylen-, Phtalocyanin-, Perinon-. Chinacridon-, Chinophtalon-, Isoindolinon-, Isoindolin-, Dioxazin-, Anthrachinoid-, Thioindigo-, Azo-, Methin- oder Azomethinreihe, einer intensiven Nassmahlung unterwirft. Die erhaltenen Pigmentlegierungen zeigen im Gegensatz zu gewöhnlichen Pigmentmischungen reinere Farbtöne, bessere applikatorische und günstigere physikalische Eigenschaften. Process for the production of pigment alloys, characterized. that you have a mixture consisting of at least two pigments from different groups of perylene, phthalocyanine, perinone. Quinacridone, quinophthalone, isoindolinone, isoindoline, dioxazine, anthraquinone, thioindigo, azo, methine or azomethine series, is subjected to intensive wet grinding.
