摘要： A radiographic silver halide film has improved processability because it includes a silver halide emulsion composed of cubic grains having a critical molar ratio of chloride, iodide, and bromide. In particular, the cubic grains comprise from 1 to 20 mol % of chloride and from 0.25 to 1.5 mol % of iodide, with the remainder being bromide. The cubic grains also have an ECD of from 0.65 to 0.8 mu m. This film is particularly useful in mammography for imaging dense soft tissue.

摘要： 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 µm, 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. The tabular silver halide grains are spectrally sensitized using a combination of spectral sensitizing dyes to provide increased speed and reduced dye stain. The dyes have maximum J-aggregate absorptions on the tabular silver halide grains of from 380 to 500 nm, wherein the maximum J-aggregate absorption of one spectral sensitizing dye is from 20 to 50 nm lower in wavelength than the maximum J-aggregate absorption of the second spectral sensitizing dye.
