Abstract

A recording material comprising a support and a thermosensitive element containing one or more of silver behenate, silver palmitate, and silver stearate, an organic reducing agent therefor in thermal working relationship therewith and a binder, wherein the silver behenate, palmitate, or stearate is not associated with mercury and/or lead ions, production processes for particles of substantially light-insensitive organic silver salt primarily comprising silver behenate, silver palmitate, or stearate, with described X-ray characteristics in the substantial absence of organic solvent.
