High contrast photographic silver halide material.
摘要
<p>A high contrast photographic material comprising a support bearing a high contrast silver halide emulsion layer which is capable of forming a latent image under conditions of use and, in the emulsion layer or an adjacent hydrophilic colloid layer, a hydrazide nucleating agent wherein the material comprises a second silver halide emulsion layer which is not capable of forming a latent image under conditions of use and wherein the silver halide contained in the image areas of both layers contributes to the visible silver image.</p>
