    摘要： A photothermographic material comprising a photosensitive silver halide, an organic silver salt, a reducing agent, and an ultrahigh contrast promoting agent, typically a hydrazine derivative. In one embodiment, a compound having a group for promoting adsorption to the silver halide is contained for suppressing occurrence of pepper fog. In another embodiment, a 5- or 6-membered heterocyclic mercapto compound having at least two nitrogen atoms or a tetraazaindene compound is contained for suppressing a change of photographic properties, typically image enlargement with a variation of developing conditions. In either case, the photothermographic material can form super-high contrast images of quality.
