摘要:
The invention provides a photothermographic material comprising a photosensitive silver halide, an organic silver salt, a reducing agent, and a binder on a support. A layer containing the organic silver salt has been formed by using a solid particle dispersion of the organic silver salt and a polymer latex as a main binder, preparing a coating solution of the salt and the binder in an aqueous solvent, and coating the solution, followed by drying. Coating operation is easy, and coating surface quality and photographic properties are improved.
