ABSTRACT:
A photographic material for recording non-silver images at high sensitivity using a small amount of silver halide, comprising a support, a layer, formed thereon, of a monovalent or divalent copper salt or complex and a hydrophilic binder, and a layer of silver halide formed on the layer containing the copper salt or complex either by vacuum-deposition or sputtering, or by coating a silver halide emulsion. Non-silver images are formed by exposing the photographic material imagewise, and developing the silver halide layer and the copper compound layer either successively with different developer solutions, or continuously in one developer solution. The silver developed acts as a catalyst for the development of the copper compound.
