摘要： Photographic silver halide material suitable for use in the silver complex diffusion transfer reversal process for the production of a continuous tone positive silver image (sensitometric curve I of the drawing) on an image-receiving material and a continuous tone negative silver image (sensitometric curve II of the drawing) in the photographic silver halide material itself, wherein the negative silver image is usable per se for serving as an internegative in a photographic printing process. In the photographic material on each side of a transparent support a silver halide emulsion layer high in silver chloride is present with a different developing agent composition to yield from the two emulsion layers together the total silver image density and average gradient desired in the negative image.
