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.

摘要： Processes are disclosed for fabricating an ink composition which uses a high pressure shearing force to produce a desired reduction and dispersion of pigment particles in a concentrated dispersion. In one disclosed process, an aqueous ink mixture including water, a solvent and a black pigment colorant dispersion is processed by a microfluidizer and filtered to obtain a desired particle size making the ink suitable for ink jet printing applications. In another process, the pigment dispersion is first microfluidized and the water and solvent added to form a mixture which is then filtered. These processes simplify the ink fabrication by eliminating a sonification and centrifugation step required by prior art processes.

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.
