Abstract
A photothermographic recording material comprising a support and a photo-addressable thermally developable element comprising photosensitive silver halide in catalytic association with a substantially light-insensitive organic silver salt, an organic reducing agent for the substantially light-insensitive organic silver salt in thermal working relationship therewith and a water-soluble or water-dispersible binder, characterized in that the substantially light-insensitive organic silver salt is a silver salt of an organic carboxylic acid, the photo-addressable thermally developable element further comprises a non-ionic or anionic surfactant and the photo-addressable thermally developable element is coatable from an aqueous medium and is capable of producing stable images without a wet-processing step; a process for producing the photothermographic recording material and a photothermographic recording process therefor.
