Abstract:
A radiographic silver halide film comprising a transparent support, said film having disposed on each side of said support, one or more hydrophilic colloid layers including at least one silver halide emulsion layer,each of said silver halide emulsion layers comprising silver halide tabular grains that (a) have the same or different composition in each silver halide emulsion layer, (b) account for at least 50% of the total grain projected area within each silver halide emulsion layer, and (c) have an average aspect ratio of greater than 5, the silver coverage on each side of said support being from about 10 to about 14 mg/dm2, each silver halide emulsion layer comprising one or more hydrophilic polymer vehicles at a total coverage of from about 7 to about 20 mg/dm2, the level of hardener on each side of said support being from about 0.3 to about 1 weight % based on total polymer vehicles on that side, said radiographic silver halide film further comprising in one or more of said silver halide emulsion layers, a colorant that is present in an amount sufficient to provide a film a* value of from about âˆ’3.2 to about âˆ’2.0 at a film b* value of âˆ’7.
