Abstract
A process was disclosed for the preparation of a heat mode recording element comprising a transparent support and a thin metal recording layer, characterized in that said thin metal layer was formed by the following steps: (1) preparing a solution containing metal ions and preferably a binder, (2) reducing said metal ions by a reducing agent, (3) coating said aqueous medium on said transparent support, optionally after removal of superfluous salts. The process disclosed is less complicated and more economic than previously known methods for applying a thin metal recording film.
