  • Publication number: 20030059702
    Abstract: Disclosed is a toner comprising particles of a resin and an optional colorant, said toner particles having coated thereon a polythiophene. 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 resin and an optional colorant, said toner particles having coated thereon a polythiophene.

  • Patent number: 6529313
    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.

  • Patent number: 6467871
    Abstract: Disclosed is a process for depositing marking material onto a substrate which comprises (a) providing a propellant to a head structure, said head structure having at least one channel therein, said channel having an exit orifice with a width no larger than about 250 microns through which the propellant can flow, said propellant flowing through the channel to form thereby a propellant stream having kinetic energy, said channel directing the propellant stream toward the substrate, and (b) controllably introducing a particulate marking material into the propellant stream in the channel, wherein the kinetic energy of the propellant particle stream causes the particulate marking material to impact the substrate, and wherein the particulate marking material comprises toner particles which comprise a vinyl resin, an optional colorant, and poly(3,4-ethylenedioxypyrrole), said toner particles having an average particle diameter of no more than about 10 microns and a particle size distribution of GSD equal to no more t
