Abstract

A thermal imaging process comprising the step of imagewise heating a donor element so as to transfer therefrom colored matter onto a contacting receptor element, characterized in that before said imagewise heating said receptor element contains in a layer at least one substance that by heat applied in the transfer of said colored matter undergoes a change giving rise to an increase in optical density.
