A silver halide color photographic material which comprises a support having provided thereon at least one silver halide emulsion layer containing a cyan dye image-forming coupler represented by the following general formula (I), wherein the emulsion layer comprises silver bromide grains or silver chloro-bromide grains in which tabular grains having a mean aspect ratio of 5 or more amount to 50% or more based on the total projection area of the whole grains, and which are spectrally sensitized with a cyanine dye of the trimethine or pentamethine type or a merocyanine dye, which dye has a desensitization degree of 10 or more, thereby achieving high sensitivity and excellent fastness of photographic images and ensuring uniform quality in mass production: ##STR1## wherein R.sub.1 and R.sub.2 each represents a substituted or ubsubstituted aliphatic, aromatic or heterocyclic group; R.sub.3 represents a hydrogen atom, a halogen atom, a substituted or unsubstituted aliphatic or aromatic group or an acylamino group, and further R.sub.3 may be non-metallic atomic groups which form with R.sub.2 a nitrogen-containing 5- or 6-membered ring; Y.sub.1 represents a hydrogen atom, or a group which is eliminable upon an oxidative coupling reaction with a developing agent; and n represents 0 or 1; and further the coupler may take a polymeric form, including a dimeric form, via a group represented by R.sub.1, R.sub.2 or Y.sub.1.
A silver halide color photographic material which comprises a support having provided thereon at least one silver halide emulsion layer containing a cyan dye image-forming coupler represented by the following general formula (I), said emulsion layer containing silver chlorobromide grains containing 40 to 95 mol % bromide in which tabular silver halide grains having a means aspect ratio of 5 to 8 amount to 85% or more based on the total projection area of the whole grains, and being spectrally sensitized with a cyanine dye of the trimethine or pentamethine type or a merocyanine dye, which dye has a desensitization degree of 10 or more, ##STR21## wherein R.sub.1 and R.sub.2 each represents a substituted or unsubstituted aliphatic, aromatic or heterocyclic group;
