Estimating the term…
A production process for a photothermographic recording material thermally developable under substantially water-free conditions comprising the steps of: (i) providing a support; (ii) producing one or more aqueous dispersions or solutions containing together a substantially light-insensitive organic silver salt, photosensitive ex-situ silver halide in catalytic association with the substantially light-insensitive organic silver salt, a reducing agent in thermal working relationship with the substantially light-insensitive organic silver salt and a binder; (iii) coating the one or more aqueous dispersions or solutions onto the support to form layers which upon drying become a photo-addressable thermally developable element; and (iv) drying the layers, wherein the photo-addressable thermally developable element contains between 0.2 and 2.5 moles of in-situ photosensitive silver iodide per mole of ex-situ photosensitive silver halide produced by reacting particles of the substantially light-insensitive organic silver salt in an aqueous dispersion with a source of iodide ion; and a recording process therefor.
A production process for a photothermographic recording material thermally developable under substantially water-free conditions comprising the steps of:
A photothermographic recording material thermally developable under substantially water-free conditions comprising a photo-addressable thermally developable clement comprising a substantially light-insensitive organic silver salt, 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, wherein part of said photosensitive silver halide is ex-situ and part of said silver halide is in-situ and said ex-situ and in-situ photosensitive silver halide is to be found in separate layers, wherein said thermally developable element contains between 0.3 and 2.0 moles of in-situ photosensitive silver iodide per mole of ex-situ photosensitive silver halide, wherein said ex-situ photosensitive silver halide is silver bromide, silver chloride, silver iodide or a mixed crystal containing any combination thereof and said thermally developable element contains a source of bromine or chlorine radicals and wherein said substantially light-insensitive organic silver salt is a silver salt of an organic carboxylic acid.
