Abstract (en)

[origin: EP0911692A2] A photothermographic element has on a support a photothermographic layer which has been formed by applying a coating solution in which a photosensitive silver halide and a binder containing at least 50 wt% of a polymer latex having a surface acid content of 0.5-8 wt% are dispersed in a solvent containing at least 30 wt% of water, followed by drying. The photothermographic element can be prepared from an aqueous coating solution which is desirable from the ecological and safety standpoints while it has improved photographic properties.
