ABSTRACT:
In an electrically activatable recording (EAR) element comprising an electrically conductive support bearing (a) a first layer, and, contiguous to the first layer, (b) an electrically activatable recording layer, image formation in the electrically activatable recording layer is aided when the first layer (a) consists essentially of a compound selected from the group consisting of silver chlorides, silver bromides, silver iodides, transition metal bromides, transition metal chlorides, alkali metal chlorides, alkali metal bromides, alkali metal iodides, mixed chlorides, bromides and iodides of such metals and combinations of such compounds. The EAR element is light handleable when free of photosensitive silver halide and provides an image, after electrically activated exposure by dry development processing or by processing in a processing solution or bath.
