Abstract
A direct thermal imaging method wherein in conjunction with an information-wise energized thermal printhead a direct thermal recording material is used that contains on a support (i) a heat-sensitive layer comprising a substantially light insensitive organic silver salt, (ii) optionally an outermost anti-friction or protective layer, and (iii) a reducing agent being present in the heat-sensitive layer and/or another layer on the same side of the support carrying the heat-sensitive layer, characterized in that said method contains the step of information-wise heating said heat-sensitive layer through a contacting but removable protection element, e.g. web or sheet, wherefrom during said heating no transfer of imaging substance(s) to said heat-sensitive layer takes place.
