摘要： PURPOSE:To improve a graininess and color reproducibility by providing a non- photosensitive intermediate layer between silver halide emulsion layers having different color sensitivities and incorporating a diffusion-resistant compd. which can release a coupling component by causing coupling reaction with the oxidant of a color developing agent therein. CONSTITUTION:One of the silver halide emulsion layers adjacent to the non- photosensitive intermediate layer is constituted with the plural layers having substantially the same color sensitivities but different photographic sensitivities. The compd. incorporated into the intermediate layer has both of the diffusion- resistant type coupler component and the scavenger component of the oxidant of the color developing agent in the molecule. The scavenger component scavenges the oxidant of the color developing agent in the color photosensitive material during development and can be discharged from, for example, a colorless compd. or multi-color photosensitive material by making coupling reaction with the oxidant of the color developing agent.

摘要： PURPOSE: To obtain a sensitive material having high sensitivity and showing superior sharpness and graininess by satisfying four conditions with respect to red-, green- and blue-sensitive emulsion layers.
CONSTITUTION: When red-, green- and blue-sensitive silver halide emulsion layers are formed on a support, a blue-sensitive silver halide emulsion layer having the highest sensitivity among red-, green- and blue-sensitive silver halide emulsion layers each having the highest sensitivity is positioned farthest from the support. The red-sensitive silver halide emulsion layer having the highest sensitivity and the green-sensitive silver halide emulsion layer having the highest sensitivity are held between the blue-sensitive silver halide emulsion layer having the highest sensitivity and a blue-sensitive silver halide emulsion layer having lower sensitivity. Red-, green- and blue-sensitive silver halide emulsion layers each having the lowest sensitivity are not present between the uppermost layer and the blue-sensitive silver halide emulsion layer having lower sensitivity. At least one layer among the red-, green- and blue-sensitive silver halide emulsion layers each having the highest sensitivity contains a diffusion resistant compound capable of forming a movable dye by a coupling reaction with the oxidized product of a color developing agent.

摘要： PURPOSE: To obtain a photosensitive material which has high sensitivity, has excellent sharpness and grain characteristic and provides an inter-image effect by providing plural photosensitive silver halide emulsion layers in specific layer order and incorporating a colored magenta coupler in the green sensitive silver halide emulsion layer.
CONSTITUTION: A green sensitive emulsion layer, red sensitive emulsion layer and plural blue sensitive emulsion layers having different photosensitivies are provided on a base. One of the plural blue sensitive emulsion layers is provided as an emulsion layer on the furthest side from the base and at least one layer of the green sensitive emulsion layer and the red sensitive emulsion layer are sandwiched by such blue sensitive emulsion layer provided on the furthest side and the blue sensitive emulsion layer having the lower photosensitivity. The emulsion layers of the green sensitive emulsion layer and red sensitive emulsion layer sandwiched by these two blue sensitive emulsion layers including the two blue sensitive emulsion layers contain single dispersible silver halide particles and the green sensitive emulsion layer sandwiched by the two blue sensitive emulsion layers contain a colored magenta coupler. The effect similar to the effect when the emulsion layers are provided without yellow filter layers is obtd. and therefore the generation of a photographic fog is suppressed while the sensitivity is high and the color clouding is decreased.
