Abstract

An electrically activatable recording (EAR) element capable of producing a positive image comprises an electrically activatable recording layer comprising a transition metal complex selected from the group consisting of Group VIIIB and Group IB metal complexes in a film forming ionic polymer that is capable of undergoing an imagewise reorientation upon exposure to electric current and, upon such exposure, development of an image in the exposed areas of the recording layer is restricted. The recording element is light handleable and provides a non-silver positive image upon exposure and processing.
