Abstract:
A process for preparing a monosheet black and white photothermographic recording material, said photothermographic recording material being exclusive of a dye-providing compound and comprising a support and a photo-addressable thermally developable element, said photo-addressable thermally developable element being thermally developable under substantially water-free conditions and consisting of one or more layers, said layers together comprising photosensitive silver halide, a substantially light-insensitive organic silver salt, a reducing agent therefor in thermal working relationship therewith and a binder, comprising the steps of: (i) coating at least one of the one or more layers of the photo-addressable thermally developable element from an aqueous medium; (ii) drying said layer or layers coated in step (i); and (iii) heating said photothermographic recording material at a temperature of at least 35Â° C. in the dark for a period of at least 3 days.
