Abstract: An electrophoretic display medium includes one or more set of colored particles in a dielectric fluid, wherein at least one of the one or more set of particles comprise particles having a cationic polymer coating thereon imparting a substantially uniform positive charge to the particles. The display medium is included in an electrophoretic display device by including the medium in a multiplicity of individual reservoirs of a display layer or layers that is located between conductive substrates.

Abstract: A wax emulsion comprised of polyethylene wax and one or more surfactants in an aqueous medium, wherein the polyethylene wax has a degree of crystallinity of from about 50% to about 80% by weight of the polyethylene wax, is provided. The wax emulsion is made by emulsifying the polyethylene wax, one or more surfactants and an aqueous medium in a vessel at a temperature at or above the melting point of the polyethylene wax to form an emulsified product, and subsequently cooling the emulsified product to ambient temperature at a cooling rate of at least 10° C. per minute. The wax emulsion is preferably incorporated into toner particles prepared by emulsion/aggregation/coalescing.

Abstract: A process for forming curable powder comprises providing an aqueous dispersi on of particles of curable resin and optionally particles comprising at least o ne curing agent; aggregating the particles optionally with the curing agent to form aggregate d particles; coalescing the aggregated particles to form fused particles; and removing th e fused particles from the aqueous dispersion. By this process, a curable powder is formed. The curable powder may be used in powder coating.

Abstract: Toner particles comprise resin, wax and optionally colorants, and the wax is substantially excluded from the interior core of the toner particles. Processes for preparing such toner particles comprise providing an aqueous dispersion of resin particles and optionally colorants, mixing the aqueous dispersion in presenc e of a coagulant, aggregating to form particles, coalescing to form fused particles , and removing the fused particles from the aqueous dispersion. Wax dispersions ca n be added either after mixing or during aggregation, so that wax is excluded fro m the core of the toner particles.
