    摘要: An electrophoretic display device includes a display layer of a multiplicity of individual microcapsules containing a display medium therein and conductive substrates, at least one of the conductive substrates being transparent, wherein the display layer is located in between the conductive substrates, and wherein the display medium includes one or more set of colored particles in a dielectric fluid and has an electric conductivity of about 10−11 to about 10−15 S/m. The microcapsules may be made by encapsulating the display medium in the wall forming material of the microcapsules, and for example a complex coacervation process may be used.

    摘要: Processes for making organic pigments useful in imaging members, specifically for pigments that after further polymorphic conversion may be used in a charge generating layer of an imaging member. More specifically, there are described processes for producing titanyl phthalocyanine (TiOPc) in high yields using tetrahydronaphthalene as reaction solvent, such as TiOPc Type I. This pigment can be successfully converted to a high sensitivity crystal form useful as charge generating pigment in an imaging member.

    摘要: A process for manufacturing a toner having improved relative humidity sensitivity is described. The process comprises forming polyester toner particles by emulsion/aggratation, fluidizing the toner particles with a stream of inert gas while spraying the toner particles with a solution containing an additive affecting relative humidity sensitivity, and wherein the additive contacts a surface of the toner particles and the additive remains on the surface of the toner particles.
