    摘要: The present disclosure relates to a magnetic toner composition. The toner composition includes one or more resins, and spherical ferromagnetic nanoparticles. Also provided is a process for preparing these toners including ferromagnetic nanoparticles. In embodiments, the aggregation of the toner is conducted at a pH greater than about 7, without the use of a coagulant. Additionally, in embodiments, freezing (stopping particle growth) and coalescence of the toner particles may be conducted at a pH greater than about 9. In yet other embodiments, the process may be conducted under an inert gas such as argon to avoid oxidation of the ferromagnetic nanoparticles during toner preparation.

    摘要: Coated phosphorescent pigments are provided which may be utilized in toner compositions. In embodiments, the phosphorescent pigment may be coated by a powder coating process. The large pigment particles may be dry blended with dried resin latex particles, thereby coating the pigment surface, followed by heating and shearing in a rotary kiln or extruder to melt the toner resin and fuse it to the pigment surface. The resulting coated particles may be utilized with other toners, in embodiments color toners, to provide phosphorescent images.
