Abstract

A room light-handleable recording material comprises an electrically conductive support having thereon in sequence (a) a polymeric electrically active conductive (EAC) layer, a recording layer (b) comprising a dye-forming coupler and an oxidation-reduction combination comprising an organic silver salt and a reducing agent having an oxidation product which reacts with the coupler to form image dye. Imagewise passage of current through the material, possibly achieved by applying a potential across the material and an exposed photoconductive layer in contact therewith, produces a heat-­ developable latent image. Higher current sensitivity of this material is obtained by using as the organic silver salt a salt of a mercapto-1,2,4-triazole derivative and as the polymer for the EAC layer a vinyl addition polymer of the structure:
