ABSTRACT:
A radiographic material containing tabular silver halide grains also includes an amido compound as an antifoggant precursor that can slowly release an antifoggant over time. These compounds are present in reactive association with the silver halide in tabular silver halide emulsion layers, and are present in an amount of at least 0.5 mmol/mol of silver. The radiographic materials are protected from fog during storage particularly in high temperature environments.
