    摘要： Disclosed is a liquid developer comprising a colorant and a substantial amount of a curable liquid vehicle having a viscosity of no more than about 500 centipoise and a resistivity of no less than about 10.sup.8 ohm-cm. One embodiment of the invention is directed to an electrophoretic liquid developer comprising a substantial amount of a curable liquid vehicle having a viscosity of no more than about 20 centipoise and a resistivity of no less than about 5.times.10.sup.9 ohm-cm, a charge control agent, and colored particles capable of becoming charged and migrating through the liquid vehicle to develop an electrostatic latent image. Another embodiment of the invention is directed to a polarizable liquid developer comprising a colorant and a substantial amount of a curable liquid vehicle having a viscosity of from about 25 to about 500 centipoise and a resistivity of from about 10.sup.8 to about 10.sup.11 ohm-cm. Yet another embodiment of the invention is directed to a photoelectrophoretic liquid developer comprising a substantial amount of a curable liquid vehicle having a viscosity of no more than about 20 centipoise and a resistivity of no less than about 5.times.10.sup.9 ohm-cm and photosensitive colored particles. A specific embodiment of the invention is directed to a liquid developer comprising a colorant, a substantial amount of a curable liquid vehicle having a viscosity of no more than about 500 centipoise and a resistivity of no less than about 10.sup.8 ohm-cm, and solid particles containing an initiator substantially insoluble in the liquid vehicle and capable, upon activation, of initiating polymerization of the curable liquid vehicle. In one embodiment, the colorant comprises pigment particles and the initiator is contained on the surfaces of the pigment particles. In another embodiment, the developer contains polymeric particles and the initiator is contained on the surfaces of the polymeric particles. In yet another embodiment, the colorant comprises toner particles which comprise a pigment and a polymer, and the initiator is contained on the surfaces of the toner particles. In still another embodiment, the initiator is contained on the surfaces of solid particles such as silicas, clays, or the like. The initiator can also be contained within the solid particles.

    摘要： Disclosed is a liquid developer comprising a colorant and a substantial amount of a curable liquid vehicle having a viscosity of no more than about 500 centipoise and a resistivity of no less than about 10.sub.8 ohm-cm. One embodiment of the invention is directed to an electrophoretic liquid developer comprising a substantial amount of a curable liquid vehicle having a viscosity of no more than about 20 centipoise and a resistivity of no less than about 5.times.10.sup.9 ohm-cm, a charge control agent, and colored particles capable of becoming charged and migrating through the liquid vehicle to develop an electrostatic latent image. Another embodiment of the invention is directed to a polarizable liquid developer comprising a colorant and a substantial amount of a curable liquid vehicle having a viscosity of from about 25 to about 500 centipoise and a resistivity of from about 10.sup.8 to about 10.sup.11 ohm-cm. Yet another embodiment of the invention is directed to a photoelectrophoretic liquid developer comprising a substantial amount of a curable liquid vehicle having a viscosity of no more than about 20 centipoise and a resistivity of no less than about 5.times.10.sup.9 ohm-cm and photosensitive colored particles. A specific embodiment of the invention is directed to a liquid developer comprising a colorant, a substantial amount of a curable liquid vehicle having a viscosity of no more than about 500 centipoise and a resistivity of no less than about 10.sup.8 ohm-cm, and solid particles containing an initiator substantially insoluble in the liquid vehicle and capable, upon activation, of initiating polymerization of the curable liquid vehicle. In one embodiment, the colorant comprises pigment particles and the initiator is contained on the surfaces of the pigment particles. In another embodiment, the developer contains polymeric particles and the initiator is contained on the surfaces of the polymeric particles. In yet another embodiment, the colorant comprises toner particles which comprise a pigment and a polymer, and the initiator is contained on the surfaces of the toner particles.

    摘要： A method for manufacturing a full color, reflective display includes the steps of depositing a first plurality of electrophoretic display elements in substantial registration with a first electrode and a second plurality of electrophoretic display elements in substantial registration with a second electrode. The electrophoretic display elements include a capsule containing a species of particles dispersed in a suspending fluid. The selective deposition of the display elements can be achieved by ink-jet printing methods, screen printing methods or other printing methods. In some embodiments the electrodes are printed onto the substrate before selective deposition of the display elements, while in other embodiments the substrate is provided having the electrodes already disposed on it. In still other embodiments, the sequence of printing of electrodes and electrophoretic display elements can be varied.

    摘要： Disclosed is a process for forming images which comprises (a) generating an electrostatic latent image; (b) contacting the latent image with a developer comprising a colorant and a substantial amount of a vehicle with a melting point of at least about 25° C., said developer having a melting point of at least about 25° C., said contact occurring while the developer is maintained at a temperature at or above its melting point, said developer having a viscosity of no more than about 500 centipoise and a resistivity of no less than about 108 ohm-cm at the temperature maintained while the developer is in contact with the latent image; and (c) cooling the developed image to a temperature below its melting point subsequent to development. Specific processes disclosed include electrophoretic development processes, polarizable liquid development processes, and photoelectrophoretic development processes. Optionally, the developed image is transferred to a substrate subsequent to development.
