Anvendelse af blandingskrystalpigmenter på basis af quinacidoner i elektrofotografiske tonere eller fremkaldere og ink-jet-blæk

摘要

The use of mixed crystal quinacridone pigments as colorants in electrophotographic toners and developers, powder lacquers, ink-jet inks, electret fibers and color filters is claimed. The pigments consist of 85-99 wt. % unsubstituted quinacridone (IA) of the beta -phase and 1-15 wt. % substituted quinacridone(s) (IB). The use of mixed crystal quinacridone pigments as colorants in electrophotographic toners and developers, powder lacquers, ink-jet inks, electret fibers and color filters is claimed. The pigments consist of 85-99 wt. % unsubstituted quinacridone (IA) of the beta -phase of formula (I): R<1>, R<2> = hydrogen (H) and 1-15 wt.% substituted quinacridone(s) (IB) of formula (I); R<1>, R<2> independently = chlorine, bromine or fluorine or 1-4 carbon (C) alkyl, 1-4 C alkoxy or carbonamido groups, optionally substituted by 1-6 C alkyl groups; R<1> may also = H Independent claims are also included for products, comprising electrophotographic toners and developers, powders and powder lacquers, ink-jet inks and hot-melt ink-jet inks, containing the pigment.
