Photothermographic material

A photothermographic material comprising

• a support in the form of a plastic film having a glass transition temperature of at least 90° C., said support having a first and a second surface, said support having been heat treated at a temperature in the range of 80° to 200° C., and said support experiences a dimensional change of less than 0.04% when heated at 115° C. for 30 seconds, and
• a photosensitive layer disposed on either the first or the second surface of the support and containing an organic silver salt, a photosensitive silver halide, a reducing agent, and an ultrahigh contrast promoting agent;
• wherein said photothermographic material further comprises a polymer layer disposed on at least the first or the second surface of the support, containing at least one of a conductive metal oxide and a conductive high molecular weight compound selected from the group consisting of polyvinyl benzenesulfonates, polyvinyl benzyltrimethylammonium chloride, quaternary salt polymers, polymer latexes, CP-1, CP-2 and CP-4 to CP-7:
