ABSTRACT:
A high-speed (over 700) radiographic silver halide film is useful for radiography to provide images with improved contrast and sharpness and reduced fog. The film includes at least one tabular grain silver halide emulsion layer on each side of a film support which grains are dispersed in a hydrophilic polymeric vehicle mixture comprising at least 0.05% of oxidized gelatin, based on the total dry weight of the hydrophilic polymeric vehicle mixture. Where multiple silver halide emulsion layers are disposed on each side of the film support, the emulsion layers closest to the support on each side can include crossover control agents to reduce crossover to less than 15%.
