ABSTRACT:
A high contrast, high density color image is formed on a silver halide photosensitive monochromatic, e.g., irradiated by X-rays, by subjecting the photosensitive material to coupling or color development with a developer solution containing a p-phenylene diamine developing agent and 1-phenyl-3-pyrazolidone and then, without desilverization, to fixing. The coupler may be contained in the silver halide photo-emulsion or in a developing solution.
