  • Self-contained imaging media comprising microencapsulated color formers and a resilient layer
    Patent number: 6649318
    Abstract: A self-contained photohardenable imaging assembly comprising in order: a first transparent support; an imaging layer comprising a developer material and a plurality of photohardenable microcapsules encapsulating a color precursor, and a second support, wherein an intermediate resilient layer is place beneath at least one support and above said imaging layer, which intermediate resilient layer has a thickness of 10 to 50 microns and comprises a relatively resilient material compared to the one support. The imaging assembly has been found to provide better image quality and more consistence sensitometric response to pressure development.
    Type: Grant

    Assignee: Eastman Kodak Company
    Inventors: Justin Z. Gao, Yongcai Wang, Charles C. Anderson
  • Self-contained imaging media comprising removable laminate
    Patent number: 6537717
    Abstract: A self-contained photohardenable imaging assembly comprising in order: a first transparent support; an imaging layer comprising a developer material and a plurality of photohardenable microcapsules encapsulating a photohardenable composition and a color precursor, and a second support, wherein the at least one support is covered by a removably adherent barrier sheet, so that the combined support and barrier sheet exhibits a low water vapor transmission rate before printing, but which barrier sheet may be removed after printing. The imaging assembly has been found to provide better image quality and more consistence sensitometric response to pressure development.

  • Photographic element containing improved interlayer
    Patent number: 5876908
    Abstract: The present invention is an imaging element including a support having a front side and a back side, at least one backing layer on the back side of the support, at least one silver halide emulsion layer superposed on the front side of the support, an interlayer superposed on the silver halide emulsion layer having a thickness of between 0.2 .mu.m and 1.2 .mu.m and a stiffness ratio of the interlayer to the silver halide emulsion layer of from 2 to 15; and a protective overcoat layer superposed on the interlayer having a thickness of from 0.3 to 2 .mu.m. The ratio of the thickness of the interlayer to the protective overcoat layer is less than or equal to 1.
