Abstract
Aqueous-based photothermographic materials that are sensitive to visible or X-radiation contain X-radiation sensitive phosphors in association with specific chemically sensitized tabular silver halide grains. The silver halide grains comprise at least 70 mol % bromide, based on total silver halide, have an average thickness of at least 0.02 &mgr;m and up to and including 0.10 &mgr;m, an equivalent circular diameter (ECD) of at least 0.5 &mgr;m and up to and including 8 &mgr;m, and an aspect ratio of at least 5:1. These materials can be imaged in any suitable fashion but preferably they have one or more photothermographic layers on both sides of the support and can be imaged using X-radiation with or without an associated phosphor intensifying screen.
