ABSTRACT:
Aqueous-based thermally sensitive emulsions and photothermographic imaging materials include photosensitive silver halide grains that comprise at least 15 mol % iodide based on total silver in the grains and are doped with bismuth (+3). These materials have increased photographic speed especially in the infrared region of the electromagnetic spectrum.
