发明名称 Silver salt diffusion transfer element comprising two silver halide layers
摘要 This invention provides a high sensitivity photosensitive element used for a silver salt diffusion transfer process and capable of producing an image having fine graininess and good quality. The photosensitive element comprises a photosensitive emulsion layer containing silver halide grains having small grain size (S layer) and another photosensitive emulsion layer containing silver halide grains having large grain size (L layer), the S layer being positioned toward the exposure side of the L layer, and the amount of silver halide contained in the S layer, the amount thereof contained in the L layer and the total amount thereof being 60-5 wt %, 40-95 wt %, and no less than 80 wt %, respectively, relative to the total amount of silver halide contained in the photosensitive element.
