摘要:
A dye-forming electrically activatable recording element comprises an electrically conductive support having thereon (a) an electrically activatable recording layer comprising in an electrically conductive polymeric binder, an organic silver salt and a reducing agent, (b) a photoconductive layer separated from (a) by an air gap of up to 20 microns, and (c) an electrically conductive layer on (b), wherein the recording layer (a) comprises in reactive association, (A) a dye-forming coupler, and (B) an oxidation-reduction combination comprising (i) an organic silver salt oxidizing agent, with (ii) a reducing agent which in its oxidized form forms a dye with the dye-forming coupler. The recording element can be room light handleable and can provide a dye image and silver image by dry development processing.
