ABSTRACT:
A photographic speed-increasing concentration of a certain organic photographic speed-increasing electron acceptor provides increased photographic speed in a charge-sensitive recording composite material having an ohmic resistivity of at least about 1.times.10.sup.10 ohm-cm. The charge-sensitive recording material can comprise (a) a first electrically conducting layer in association with (b) a photoconductor layer, (c) an electrically activated recording layer comprising an image-forming combination of (i) an organic, heavy metal salt oxidizing agent with (ii) a reducing agent and (iii) the described speed-increasing electron acceptor, and a binder, and (d) a second electrical conducting layer. This recording material can be room light handleable and can provide a developed image with increased speed by dry development subsequent to electrical exposure.
