  • Patent number: 6562559
    Abstract: A radiation-sensitive emulsion comprised of silver halide grains (a) containing greater than 50 mole percent chloride, based on silver, (b) having greater than 50 percent of their surface area provided by {100} crystal faces, and (c) having a central portion accounting for up to 99 percent of total silver and containing (i) a first dopant comprising an iridium coordination complex containing at least one thiazole ligand and (ii) a second dopant comprising an iridium coordination complex containing at least one substituted thiazole ligand. The combined use of first and second iridium dopants in accordance with the invention provides enhanced toe contrast softening, and can also result in improved latent image keeping stability relative to that expected from the individual effects of such dopants.

  • Patent number: 6368781
    Abstract: The invention relates to a photographic element comprising a support and a silve halide emulsion layer wherein the silver halide emulsion contains at least one absorber dye and at least one sensitizing dye. The wavelength of maximum absorbance of said absorber dye and the wavelength of maximum sensitivity of the emulsion provided by the spectral sensitizing dye are substantially the same. The emulsion is chemically sensitized with a stable and water soluble AuI) complex. This provides manufacturing improvements, improved detail and sharpness, improved dodging and burning and lower cost without an unwanted increase in heat sensitivity.

    Date of Patent: April 9, 2002
    Assignee: Eastman Kodak Company
    Inventors: Pamela M. Ferguson, Roger Lok, Alton L. Chitty, Norman R. Oneal
  • Patent number: 5994050
    Abstract: The invention relates to a method of improved burning and dodging comprising providing a color photographic element that prior to development has CIELAB coordinates such that L* is greater than 71, exposing said paper, wherein during exposure burning and dodging is carried out.
    Type: Grant

    Date of Patent: November 30, 1999
    Assignee: Eastman Kodak Company
    Inventors: Roupen H. Maronian, Donald R. Diehl, Pamela M. Ferguson, Joseph E. LaBarca
  • Patent number: 5962211
    Abstract: The invention relates to a photographic element comprising at least one absorber dye and at least one sensitizing dye wherein the peak sensitivity of said absorber dye and said sensitizing dye are similar. This provides improved perceptual red detail in regions of high red density in the negative image.
    Type: Grant

    Date of Patent: October 5, 1999
    Assignee: Eastman Kodak Company
    Inventors: Roupen H. Maronian, Donald R. Diehl, Pamela M. Ferguson
  • Patent number: 5563024
    Abstract: An improved image display material comprising a light sensitive tabular grain silver chloride emulsion spectrally sensitized to a peak wavelength of less than about 475 nm, and a method of use comprising the step of optically printing a color image onto the improved color photographic display material is provided. The material and method enable reduced printing times, improved color reproduction and lowered image granularity.
