Abstract
A process for producing a photothermographic recording material having a support and a photo-addressable thermally developable element containing photosensitive silver halide in catalytic association with a substantially light-insensitive silver salt of an organic carboxylic acid, an organic reducing agent for the substantially light-insensitive silver salt of an organic carboxylic acid in thermal working relationship therewith and a binder including a water-soluble binder, a water-dispersible binder or a mixture of a water-soluble binder and a water-dispersible binder, comprising the steps of: (i) producing an aqueous dispersion or aqueous dispersions containing photosensitive silver halide, a substantially light-insensitive silver salt of an organic carboxylic acid, an organic reducing agent for the substantially light-insensitive silver salt of an organic carboxylic acid and a binder including a water-soluble binder, a water-dispersible binder or a mixture of a water-soluble binder and a water-dispersible binder; (ii) coating the aqueous dispersion or aqueous dispersions onto a support thereby forming a photo-addressable thermally developable element on the support, wherein at least 80 mol % of the photosensitive silver halide is silver iodide and the aqueous dispersion further contains or the aqueous dispersions further contain a diazine compound.
