Abstract
The second silver halide photosensitive material comprises a substrate and at least one photosensitive silver halide emulsion layer formed thereon, the silver halide photosensitive material comprising at least two types of silver halide grains with different projected areas having photosensitivity in the same photosensitivity range; silver halide grains having a larger projected area having a refractive index n1 and an average thickness a, and silver halide grains having a smaller projected area having a refractive index n2 and an average thickness b; and the silver halide grains satisfying the conditions defined by the following equation (1): n2≦n1, and a≦b×(n2/n1) (1).
Claims20
A silver halide photosensitive material comprising a substrate and at least one photosensitive silver halide emulsion layer formed thereon, wherein said photosensitive silver halide emulsion layer comprises a silver halide emulsion comprising silver halide grains, a silver salt of a benzotriazole compound, a mercaptotetrazole compound and a reducing agent, a silver chloride content of said silver halide grains being 50 mole % or more, a molar ratio of said silver salt of a benzotriazole compound to said silver halide grains being 1 mole % or more, and a molar ratio of said mercaptotetrazole compound to said silver halide grains being 0.1 mole % or more.
A silver halide photosensitive material comprising a substrate and at least one photosensitive silver halide emulsion layer formed thereon, wherein said silver halide photosensitive material comprises at least two types of silver halide grains with different projected areas having photosensitivity in the same photosensitivity range;
- silver halide grains having a larger projected area having a refractive index n1 and an average thickness a, and silver halide grains having a smaller projected area having a refractive index n2 and an average thickness b among said at least two types of silver halide grains;
- and said silver halide grains satisfying the conditions defined by the following equation (1):
- n2≦n1, and a≦b×(n2/n1) (1).
