Abstract

PURPOSE:To obtain a clear image with high maximum density and low minimum density by adding an internal latent image type silver halide emulsion having fogging nuclei to a layer contg. an unfogged internal latent image type silver halide emulsion or other layer. CONSTITUTION:A sensitive material is manufactured by adding an unfogged internal latent image type silver halide emulsion and an internal latent image type silver halide emulsion having fogging nuclei to the same layer or separate layers in 10: 0.03-10:30 molar ratio on the basis of silver halide. Thus, a direct positive type photographic sensitive material with sufficient photosensitivity, high maximum density and low minimum density is obtd. while saving the amount of used silver halide.
