  • Patent number: 5570240
    Abstract: A transflective optical filter comprises a single transparent or transluscent substrate; a colored slice made up of a plurality of layers, each corresponding to one color out of at least two colors; a light diffusing layer; and an opaque mask on which the marks to be displayed in color are represented by transparent zones, the colored slice and the mask consisting of photographic emulsions. A method for making that filter involves multiple exposures of a same film having a multi-colored "slice" and a monochrome photosensitive layer.

  • Patent number: 5558977
    Abstract: Imaging elements, such as photographic, electrostatographic and thermal imaging elements, are comprised of a support, an image-forming layer, a transparent magnetic layer comprising magnetic particles dispersed in a film-forming binder and a transparent electrically-conductive layer comprising a sputter-deposited layer of a metal oxide. Use of a sputter-deposited metal oxide provides a controlled degree of electrical conductivity and beneficial chemical, physical and optical properties which adapt the electrically-conductive layer for such purposes as providing protection against static or serving as an electrode which takes part in an image-forming process.

  • Patent number: 5531913
    Abstract: An aqueous coating composition for forming a transparent magnetic recording layer contains a fine solid particle aqueous dispersion of dispersed magnetic particles, gelatin, and a polyelectrolyte having a molecular weight of at least 50,000. The coating composition may be prepared by milling an aqueous slurry of magnetic particles and a surface active dispersant having an HLB number of at least 8 until there are substantially no agglomerates of magnetic particles present, and then combining the milled dispersion with the gelatin and polyelectrolyte. The coating composition can be used to prepare magnetic recording elements and, in particular, photographic elements having a transparent, substantially haze-free magnetic recording layer.

  • Patent number: 5518844
    Abstract: In a first processing step, whether a first photosensitive material is a particular photosensitive material is detected. If it is detected at least that the first photosensitive material is the particular photosensitive material, processing conditions in the first processing step are recorded in a predetermined position on the first photosensitive material. Exposure conditions in the exposure step are set in accordance with one of the result of the detection and the processing conditions recorded on the first photosensitive material. The second photosensitive material is exposed under the set exposure conditions. If the first photosensitive material is detected to be a particular photosensitive material, the setting of the exposure conditions is changed in the exposure step, and the exposure conditions are set in such a manner as to compensate the difference in the characteristic occurring in the image of the particular first photosensitive material depending on standard processing and particular processing.
