Abstract:
A blue-sensitive, radiographic silver halide film comprising a support having first and second major surfaces,said radiographic silver halide film having disposed on said first major support surface, one or more hydrophilic colloid layers including a first silver halide emulsion layer, and on the second major support surface, one or more hydrophilic colloid layers including a second silver halide emulsion layer, said first 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 that comprise at least 90 mol % bromide and up to 6 mol % iodide, based on total silver halide, wherein said tabular silver halide grains in said first silver halide emulsion layer are dispersed in a hydrophilic polymeric vehicle mixture comprising at least 0.5% of oxidized gelatin, based on the total dry weight of said polymeric vehicle mixture.
