ABSTRACT:
A photographic material comprising a support coated at one side with one or more silver halide emulsion layers and at the opposite side with an electroconductive interlayer which in its turn is coated with a photoconductive layer essentially consisting of at least one organic photoconductive compound, said silver halide emulsion layer or layers being of the type that yield a latent image on exposure with actinic light and of which the latent image is developable to a silver image with a reducing agent applied as developing agent in silver halide photography, said electroconductive interlayer having a resistivity being at least 1000 times smaller than that of the photoconductive layer, and the composition of the non-developed photographic material being such, that the combined spectral density of the support, of the conductive interlayer and of the photoconductive layer does not exceed 0.3 in the wavelength range of 400 to 700 nm.
