Title:
SILVER HALIDE COLOR PHOTOSENSITIVE MATERIAL
Document Type and Number:
WIPO Patent Application WO/2004/046815
Kind Code:
A1
Abstract:
A silver halide color photosensitive material exhibiting a high photosensitivity, an excellent granularity, a low humidity−dependence in photographing, and a favorable radiation fog resistance. The material is characterized in that at least one of the photosensitive layers of the material contains a silver halide emulsion made of silver halide particles, at least 50% of the total projection area of the silver halide particles contained in the silver halide emulsion includes two twin planes parallel to a major surface, the silver halide flat particles satisfies expression (1) shown below and has an aspect ratio of 8 or more, and the content of fog particles in the unsensitized silver halide emulsion is 1&sol 20 or less. Expression (1) 1.0 ≤ b&sol a ≤ 1.3 [In the expression, a is the shorter one of the distance from one of the opposed major surfaces to the nearest twin plane and the distance from the other to the nearest twin plane when a line passing the center of the particle diameter is drawn vertically to the opposed major surfaces, and b is the longer one.]
