摘要：
Photographic elements and processes feature photoconductive, substantially silver halide free, inorganic particles and a photoreactive sulfur compound which will react with the inorganic particles upon exposure to light to form sulfur containing sites for physical development. Subsequent to exposure, the element is physically developed to produce a negative of the original.
