ABSTRACT:
The present invention relates to photography and, more particularly, to a novel radiation recording photographic diffusion transfer process film unit which comprises a photosensitive element which includes, in combination, a particulate dispersion of photosensitive crystals, preferably, photosensitive silver halide crystals adapted to be reduced to silver, upon contact with a silver halide reducing agent, as a function of the crystals' exposure to incident actinic electromagnetic radiation, having associated therewith an inorganic semiconductor adapted to donate electrons to the photosensitive crystals as a function of the exposure of the element to incident actinic electromagnetic radiation.
