Zusammenfassung:Title PD-2207-A Fluorescent Toners Surface Coated With Polymeric Quaternary Ammonium Compound And Slip Agent of Invention Fluorescent dry nonelectroscopic toner comprising fluorescent pigmented organic resin particles having a size distribution of 0.2 to 50 micrometers, surface coated with at least 0.1% by weight of silicone oil or fluorocarbon compound, in combination with at least 0.5% by weight of a water soluble, polymeric quaternary ammonium compound as defined. The fluorescent toner is useful in color developing positive- and negative-working photosensitive elements. The toners provide good toning quality and excellent lack of background color, together with stability on aging.
