ABSTRACT:
In an electrically activatable recording element, such as one comprising an electrically conductive support having thereon, in sequence: (a) a polymeric electrically active conductive (EAC) layer, (b) an electrically activatable recording layer comprising (A) a dye-forming coupler, and (B) an oxidation-reduction combination comprising (i) an organic silver salt oxidizing agent, such as a silver salt of a 1,2,4-mercaptotriazole derivative, with (ii) a reducing agent which, in its oxidized form, forms a dye with the dye-forming coupler, (c) a photoconductive layer separated from (b) by an air gap of up to 20 microns, and (d) an electrically conductive layer; improvements are provided by means of a polymeric EAC layer (a) comprising a halogen containing polyester, such as poly(2,2'-oxydiethylene:2,2'-dimethyl 1,3-propylene 50:50-2,5-dibromoterephthalate) and poly(ethylene:2,2-dimethyl-1,3-propylene 50:50-2,5-dibromoterephthalate). The recording element is room light handleable and provides a dye image and silver image by dry development processing.
