Abstract
Abstract There is disclosed a light-sensitive silver halide color photographic material comprising a support and at least one light-sensitive silver halide emulsion layer applied thereon and containing a photographic coupler which reacts with an oxidized form of a color developing agent to form a dye, characterized in that the silver halide included in said light-sensitive silver halide emulsion layer is composed of a silver halide substantially free from iodine, and grains of said silver halide are distributed therein in a monodisperse state and are contained therein in a proportion of 5 x 10" grains/m 2 or more, and said photographic coupler is contained in said light-sensitive silver halide emulsion layer so that the amount of said photographic coupler may be 3.5 x 10 -15 gram equivalent or less per grain of said silver halide.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
158 words
A light-sensitive silver halide color photographic material comprising a support and at least one light-sensitive silver halide emulsion layer applied thereon and containing a photographic coupler which reacts with an oxidized form of a color developing agent to form a dye, characterized in that the silver halide included in said light-sensitive silver halide emulsion layer is composed of a silver halide substantially free from iodine, and grains of said silver halide are distributed therein in a monodisperse state satisfying the following formula (I): wherein wherein r i is the grain diameter of the i-th grains, and n i is the number of the i-th grains. and are contained therein in a proportion of 5 x 10 11 grains/m 2 or more, and said photographic coupler is contained in said light-sensitive silver halide emulsion layer so that the amount of said photographic coupler may be 3.5 x 10- 15 gram equivalent or less per grain of said silver halide.
Claim 2
Dependent Claim
158 words
A light-sensitive silver halide color photographic material comprising a support and at least one light-sensitive silver halide emulsion layer applied thereon and containing a photographic coupler which reacts with an oxidized form of a color developing agent to form a dye, characterized in that the silver halide included in said light-sensitive silver halide emulsion layer is composed of a silver halide substantially free from iodine, and grains of said silver halide are distributed therein in a monodisperse state satisfying the following formula (I): wherein wherein r i is the grain diameter of the i-th grains, and n i is the number of the i-th grains. and are contained therein in a proportion of 5 x 10 11 grains/m 2 or more, and said photographic coupler is contained in said light-sensitive silver halide emulsion layer so that the amount of said photographic coupler may be 3.5 x 10- 15 gram equivalent or less per grain of said silver halide.
