发明名称 Silver halid color photographic photosensitive material
摘要 Disclosed is a silver halide color photographic photosensitive material in which the photosensitive layer of the photosensitive material comprising a silver halide emulsion, a developing agent and a coupler is put together with the processing layer of a processing material so that these layers are heated to form a color image in the photosensitive material, said silver halide grains in the photosensitive layer having a silver chloride content of 50 mol% or more, wherein (1) the silver halide grains, in which 50% or more of the exterior faces of the grain is made up of a (111) plane, account for 50% or more of the total projected area of the silver halide grains of the emulsion, and the developing agent has a specific molecular structure, or (2) the tabular silver halide grains having an aspect ratio of 2 or more, which have the exterior faces of the grain made up of a (100) plane and a plane of projection of the grain in a shape of a rectangle with a length to width ratio ranging from 1:1 to 1:2, or which have the exterior faces of the grain made up of a (111) plane and a plane of projection in the shape of a hexagon with the ratio of the lengths of the neighboring sides ranging from 1:1 to 1:10, account for 50% or more of the total projected area of the silver halide grains of the emulsion, and the coupler is a pyrazolotriazole coupler having a specific molecular structure.
