    摘要： A protective, switchable layer adapted for use in transient imageable documents is disclosed. The protective layer can be disposed on an underlying photochromic layer and enables writing or imaging the underlying layer. The protective layer prevents unintentional writing on the photochromic layer, such as can otherwise occur from exposure to certain wavelengths of light.

    摘要： An image-forming medium and methods for forming and imaging the medium are provided. The disclosed medium can be strongly colored under room illumination (or deliberate UV) and can be selectively discolored at an appropriate light wavelength to form an image. In one embodiment, the image-forming medium can include a substrate (e.g., a sheet of paper), a photochromic material incorporated with the substrate, and a photo-absorbing material incorporated with the photochromic material. Exemplary methods for using the image-forming medium to make a transient image can include first forming the image-forming medium by applying a coating solution containing photochromic material to the substrate or paper. The image-forming medium can have a medium color and can then be selectively exposed to a radiation through a mask to convert the photochromic material from a colored form to a colorless form and thus to form an image having a color contrast with its background.

    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： 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.
