摘要

TitleProcess of Preparing TonerTreated With Polymeric QuaternaryAmmonium Salt And Slip AgentAbstract of InventionProcess of preparing dry nonelectroscopictoner comprising pigmented organic resin particleshaving a size distribution of 0.2 to 30 micrometers,surface coated with at least 0.1% by weight ofsilicone oil or fluorocarbon compound, in combinationwith at least 0.5% by weight of a water soluble,polymeric quaternary ammonium compound as defined.The toner is useful in color developing positive- andnegative-working photosensitive element. Thetoners, particularly magenta and cyan, exhibit highdensity and excellent stability.
