  • Patent number: 6258505
    Abstract: An imaging medium comprises a substrate carrying a color-change layer. This color-change layer comprises two layers or phases comprising two color-forming reagents which react upon heating to cause a change in the color of the layer. The color-change layer is deactivated by exposure to actinic radiation such that after deactivation it no longer undergoes its thermal color-change. The color-change layer is detachable from the substrate by heating to a temperature lower than required to cause the color change, so that upon contact of the imaging medium with a receiving sheet each individual pixel of the color-change layer may be left attached to the substrate, transferred to the receiving sheet but left uncolored, or transferred to the receiving sheet and colored to a color level determined by the energy used in the associated thermal print head element.

  • Patent number: 5952148
    Abstract: The invention discloses that a photograph with a 3-dimensional image results when the non-angular reflector (of mercury) used in the Lippmann process of color photography is replaced by an angular reflector; the preferred form of the angular reflector is a retro-reflector.A photographic system is described which produces photographs with 3-dimensional images. The photo-sensitive element records the interference patterns of light waves, and the system is an improvement over the Lippmann process of color photography which produces photographs with 2-dimensional images. A photographic system is also described that produces a photograph with a 3-dimensional image from 2-dimensional cross sections of a subject; the system is useful in medical imaging. During exposure, motion of more than one wavelength of light is permissible between the subject and lens or the lens and the photo-sensitive element.These improvements result from the use of a particular type of angular reflector which is a retro-reflecting sheet.

  • Patent number: 5948588
    Abstract: The invention discloses that a photograph with a 3-dimensional image results when the non-angular reflector (of mercury) used in the Lippmann process of color photography is replaced by an angular reflector; the preferred form of the angular reflector is a retro-reflector.A photographic system is described which produces photographs with 3-dimensional images. The photo-sensitive element records the interference patterns of light waves, and the system is an improvement over the Lippmann process of color photography which produces photographs with 2-dimensional images.

  • Patent number: 5912109
    Abstract: Imaging elements, such as photographic, electrostatographic and thermal imaging elements, comprised of a support, an image-forming layer and an electrically-conductive layer consisting essentially of electrically-conductive fine particles, such as antimony-doped tin oxide particles and, as a binder, water-insoluble polymer particles. The use of water-insoluble polymer particles of an appropriate shear modulus as a binder in the electrically-conductive layer provides a layer with a high degree of conductivity at low concentrations of electrically-conductive fine particles.
