    Abstract: Disclosed is a toner comprising particles of a polyester resin, an optional colorant, and polypyrrole, wherein said toner particles are prepared by an emulsion aggregation process. Another embodiment of the present invention is directed to a process which comprises (a) generating an electrostatic latent image on an imaging member, and (b) developing the latent image by contacting the imaging member with charged toner particles comprising a polyester resin, an optional colorant, and polypyrrole, wherein said toner particles are prepared by an emulsion aggregation process.

    Abstract: An electrophoretic display liquid composition for use in an electrophoretic display device that has a multiplicity of individual reservoirs, each containing the liquid, contains one or at least two sets of particles dispersed in a transparent and/or colored liquid system. The at least two sets of particles exhibit different, contrasting color and different charging properties from each other, while in the one particle system, the particles exhibit a different, contrasting color from the colored liquid. In all embodiments, at least one of the sets of particles are particles with adjustable morphology made from emulsion/aggregation process. The morphology of the particles is controlled to be from grape, cauliflower, raspberry, or potato up to substantially perfect spheres. The transparent liquid system may include two immiscible liquids having different densities with the sets of particles having densities in between the densities of the two immiscible liquids such that the particles rest at an interface between the two immiscible liquids.
