Abstract

A substantially light-insensitive thermographic recording material substantially exclusive of cationic surfactants in which at least one non-cationic surfactant is present, wherein the thermographic recording material comprises a support and a thermosensitive element containing a substantially light-insensitive organic silver salt, a reducing agent therefor in thermal working relationship therewith and a binder, characterized in that all the non-cationic surfactants present in the thermographic recording material together have a non-fluoro-halide ion concentration of 1500ppm or less; and a process for the production thereof.
