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 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.

摘要: High performance radiographic films exhibit visually adaptive contrast when imaged in radiographic imaging assemblies comprising an intensifying screen on both sides. These films having a single silver halide emulsion on each side of a film support and are free of particulate dyes that are conventionally used to control crossover. In addition, the films can be rapidly processed to provide the desired image having visually adaptive contrast, that is the upper scale contrast is at least 1.5 times the lower scale contrast. Thus, dense objects can be better seen at the higher densities of the radiographic image without any adverse sensitometric changes in the lower scale densities. These films are useful for general-purpose radiographic imaging using a wide variety of exposure and processing conditions.

摘要: Radiographic silver halide materials coated onto a support contain a portion of the developer chemistry incorporated within the radiographic film. The remainder of the developer chemistry is contained in a developer solution. Use of a reflective support permits the developed materials to be viewed without a light box.
