Abstract:
An X-radiation sensitive photothermographic material comprising a support having on at least one side thereof, one or more imaging layers each comprising a hydrophilic binder, and in reactive association:a. chemically sensitized photosensitive silver halide grains, at least 70% of the total photosensitive silver halide grain projected area being provided by tabular silver halide grains comprising at least 70 mol % bromide, based on total silver halide, with the remainder of the halide being iodide or chloride, said tabular grains having an average thickness of at least 0.02 &mgr;m and up to and including 0.10 &mgr;m, an equivalent circular diameter of at least 0.5 &mgr;m and up to and including 8 &mgr;m, and an aspect ratio of at least 5:1, b. a non-photosensitive source of reducible silver ions, c. a reducing agent composition for said reducible silver ions, and d. a phosphor that is sensitive to X-radiation and is present in an amount of at least 0.1 mole per mole of total silver.
