Abstract

A thermographic recording material comprising a support and a thermosensitive element containing a substantially light-insensitive silver salt of an organic carboxylic acid, a reducing agent therefor in thermal working relationship therewith and at least one proteinaceous binder, characterized in that the thermosensitive element contains between 700ppm and 5ppm of a non-fluoro-halide ion with respect to the proteinaceous binders in the thermosensitive element and the thermographic recording material is thermally developable under substantially water-free conditions; and a process for the production thereof.
