  • Patent number: 6686115
    Abstract: A blue-sensitive, radiographic silver halide film comprises a silver halide emulsion layer comprising predominantly tabular silver halide grains that have an aspect ratio of at least 15, a grain thickness of at least 0.1 &mgr;M, and comprise at least 90 mol % bromide and from about 0.5 to about 2.75 mol % iodide, based on total silver halide. Substantially all of the iodide is present in an internal localized portion of the tabular silver halide grains that excludes the surface of the grains. The tabular silver halide grains are dispersed in a hydrophilic polymeric vehicle mixture comprising at least 0.5% of oxidized gelatin, based on the total dry weight of the polymeric vehicle mixture in the emulsion layer. In addition, the tabular grain emulsion includes a mercapto-substituted benzothiazole, benzoxazole, or benzimidazole to provide desired image tone and processability.

  • Patent number: 6686118
    Abstract: A blue-sensitive, radiographic silver halide film comprises a silver halide emulsion layer comprising predominantly tabular silver halide grains that have an aspect ratio of at least 15, a grain thickness of at least 0.1 &mgr;m, and comprise at least 90 mol % bromide and up to 4 mol % iodide, based on total silver halide. Substantially all of the iodide is present in an internal localized portion of the tabular silver halide grains that excludes the surface of the grains. The tabular silver halide grains are dispersed in a hydrophilic polymeric vehicle mixture comprising at least 0.5% of oxidized gelatin, based on the total dry weight of the polymeric vehicle mixture in the emulsion layer.

  • Patent number: 6686119
    Abstract: A blue-sensitive, radiographic silver halide film comprises a silver halide emulsion layer comprising predominantly tabular silver halide grains that have an aspect ratio of from 8 to 14.5, a grain thickness of from about 0.15 to about 0.3 &mgr;m, and comprise at least 90 mol % bromide and up to 6 mol % iodide, based on total silver halide. The tabular silver halide grains are dispersed in a hydrophilic polymeric vehicle mixture comprising at least 0.5% of oxidized gelatin, based on the total dry weight of the polymeric vehicle mixture in the emulsion layer.

  • Patent number: 6372418
    Abstract: A silver halide light sensitive photographic print element is disclosed comprising a support bearing on one side thereof: a blue color sensitive record comprising at least one blue-sensitive silver halide emulsion yellow-image forming layer, a red color sensitive record comprising at least one red-sensitive silver halide emulsion cyan-image forming layer, and a green color sensitive record comprising at least one green-sensitive silver halide emulsion magenta-image forming layer; wherein the overall contrast (OC) of the green record is greater than 1.7, the mid-scale contrast (MSC) of the green record is less than 2.6, and the upper-scale contrast (USC) of the green record is from 2.85 to 3.15, wherein the parameters OC, MSC and USC are as defined herein. Color print film silver halide photographic elements in accordance with the invention enable the production of outstanding projected images having improved flesh tone and shadow detail reproduction, and sufficiently high black densities.

  • Patent number: 5451490
    Abstract: An electronic printing method which comprises subjecting a radiation sensitive silver halide emulsion layer of a recording element to actinic radiation of at least 10.sup.-4 ergs/cm.sup.2 for up to 100 microseconds duration in a pixel-by-pixel mode is disclosed. The radiation sensitive silver halide emulsion layer contains a silver halide grain population comprising at least 50 mole percent chloride, based on silver, forming the grain population projected area. At least 50 percent of the grain population projected area is accounted for by tabular grains that are bounded by {100} major faces having adjacent edge ratios of less than 10, each having an aspect ratio of at least 2.
