摘要： Disclosed is an electrophotographic liquid developer composition comprising a liquid medium, first toner particles charged to one polarity and comprising a resin and a first pigment, second toner particles charged to a polarity opposite to that of the first toner particles and comprising a resin and a second pigment of a color different from that of the first pigment, and a charge director. The disclosed developer is suitable for developing electrostatic latent images in two different colors in a single development step. The latent image comprises three areas of charge; toner particles of one color are selectively attracted to one area, toner particles of the other color are selectively attracted to the second area, and the third area remains undeveloped as a background area.

摘要： Disclosed is an electrophotographic liquid developer composition comprising a liquid medium, first toner particles charged to one polarity and comprising a first dye and polymeric cores to which steric stabilizer polymers have been attached, second toner particles charged to a polarity opposite to that of the first toner particles and comprising a second dye of a different color than the first dye and polymeric cores to which steric stabilizer polymers have been attached, and a charge director. The disclosed developer is suitable for developing electrostatic latent images in two different colors in a single development step. The latent image comprises three areas of charge, toner particles of one color are selectively attracted to one area, toner particles of the other color are selectively attracted to the second area, and the third area remains undeveloped as a background area.

摘要： A stable colored liquid developer and method for making such are described wherein an improved optical density resulting from a colored dye being imbibed into a thermoplastic resin core occurs. In particular, the liquid developer comprises a marking particle dispersed in an aliphatic dispersion medium, the marking particle comprises a thermoplastic resin core having an amphipathic block or graft copolymeric steric stabilizer irreversibly chemically or physically anchored to the thermoplastic resin core with the dye being imbibed in the resin core and being soluble therein and insoluble in the dispersion medium. The stable colored liquid developer is preferably made by first preparing a graft or block copolymer amphipathic steric stabilizer, anchoring said stabilizer to a thermoplastic resin core, and to the aliphatic disperion of said particle adding a solution of a dye dissolved in a polar solvent, preferrably methanol, the dye being soluble in the thermoplastic resin core to enable it to be imbibed therein and substantially insoluble in the dispersion medium.

摘要： A method of making a phase change ink composition includes adding to a device with a stirring element at least one pigment, at least one dispersant and at least one synergist, processing the device at an elevated temperature and at a stirring rate to wet the at least one pigment to obtain an ink concentrate, and mixing the ink concentrate with an ink vehicle to obtain the ink composition. The device may be an extruder, an attritor or the like. The method allows for the reduction in the amount of dispersant to include in the ink.

摘要： A solvent-less process for producing a transient document which is capable of self-erasing, wherein the solvent-less process includes a) heating and reacting a photochromic compound and a polymer to form a coating composition, and b) coating the coating composition onto an image-receiving side of a transient document substrate, and further an image forming method using the same solvent-less process and including (i) providing a reimageable medium of a substrate and a photochromic material, wherein the medium is capable of exhibiting a color contrast and an absence of the color contrast; (ii) exposing the medium to an imaging light corresponding to a predetermined image to result in an exposed region and a non-exposed region, wherein the color contrast is present between the exposed region and the non-exposed region to allow a temporary image corresponding to the predetermined image to be visible for a visible time; (iii) subjecting the temporary image to an indoor ambient condition for an image erasing time to change the color contrast to the absence of the color contrast to erase the temporary image without using an image erasure device; and (iv) optionally repeating procedures (ii) and (ii) a number of times to result in the medium undergoing a number of additional cycles of temporary image formation and temporary image erasure.
