Abstract:
A photothermographic recording material comprising a photo-addressable thermally developable element comprising a substantially light-insensitive organic silver salt, in situ formed photosensitive silver halide in catalytic association with said substantially light-insensitive organic silver salt and a reducing agent in thermal working relationship with said substantially light-insensitive organic silver salt and a binder, characterized in that said binder comprises a water soluble polymer, a water-dispersible polymer or a mixture of a water soluble polymer and a water-dispersible polymer and particles of said photosensitive silver halide are non-aggregating in said photo-addressable thermally developable element and are uniformly distributed over and between particles of the substantially light-insensitive organic silver salt, at least 80% by number of said silver halide particles having a diameter, determined by transmission electron microscopy, of <25 nm.
