Photothermographic elements |
(57) 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.
