Beschreibung
Zusammenfassung:	6-substituted-2,4-bis(trichloromethyl)s-triazine stabilizer precursor compounds having maximum absorption wavelengths greater than 320 nanometers and being thermally stable at temperatures up to 150 DEG C provide improved post-processing stability in a photothermographic silver halide material designed for dry physical development. Such a photothermographic material comprises photographic silver halide and an image forming combination comprising (i) an organic silver salt oxidizing agent, with (ii) a reducing agent for the silver salt oxidizing agent. A developed visible image is provided after imagewise exposure by uniformly heating the photothermographic material to moderately elevated temperatures.
