摘要： A photothermographic material is prepared by preparing an aqueous dispersion of a thermoplastic resin, adding an organic silver salt and a silver halide to the aqueous dispersion, further adding a ultrahigh contrast promoting agent to the aqueous dispersion to form an aqueous coating solution, applying the aqueous coating solution to a support, and heat drying the coating. Since the use of an aqueous dispersion enables the use of a polycarbonate support which originally has good dimensional stability to heat, a photosensitive material having good dimensional stability is manufactured in high yields.
