A silver halide color photographic light sensitive material is disclosed, comprising a support having thereon a silver halide emulsion layer containing a sensitizing dye represented by formula (I) and a coupler represented by formula (M-I). The photographic material further contains a coupler represented by formula (C-I) or (C-II). ##STR1##

Silver halide color photographic light sensitive material

The improved silver halide photographic material has one or more silver halide emulsion layers on a support and at least one of said emulsion layers contains silver halide grains which are of normal crystal form having at least one concave crystal face. This photographic material has not only high sensitivity but also good keeping quality.

Silver halide photographic material having improved keeping quality

A photosensitive silver halide photographic material having a support and, provided thereon, the photographic component layers including at least one silver halide emulsion layer containing silver halide grains (1) having at least two kinds of halogens, is disclosed. The silver halide grains (1) are grown to in a system in the presence of silver halide grains (2) coexisting:

Photosensitive silver halide photographic material

The present invention relates to a silver halide photographic material having one or more light-sensitive silver halide emulsion layers on a support, which said photographic material is characterized in that at least one of said light-sensitive emulsion layers contains silver halide grains that are spectrally sensitized with at least one of the spectral sensitizers represented by the following general formula (I) and further contains at least one of the compounds represented by the following general formulas (II) and (III): ##STR1## wherein the variables are as defined in the specification.

Spectrally sensitized silver halide photographic material

A silver halide photographic material in which at least one silver halide emulsion layer coated onto a base support has been subjected to supersensitization by the combination of at least one symmetrical carbocyanine dye having two symmetrical heterocyclic structures, at least one other symmetrical carbocyanine dye having two symmetrical heterocyclic structures, and at least one asymmetrical carbocyanine dye having either one of the two heterocyclic structures in the first symmetrical carbocyanine dye and either one of the two heterocyclic structures in the second symmetrical carbocyanine dye. This photographic material has high spectral sensitivity and good storage stability since it is resistant to desensitization due to desorption of spectral sensitizers from silver halides.
