| titleOfInvention | Silver halide color photographic material |
| abstract | 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: <IMAGE> (I) wherein R1 and R2 each represents a substituted or ubsubstituted aliphatic, aromatic or heterocyclic group; R3 represents a hydrogen atom, a halogen atom, a substituted or unsubstituted aliphatic or aromatic group or an acylamino group, and further R3 may be non-metallic atomic groups which form with R2 a nitrogen-containing 5- or 6-membered ring; Y1 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 R1, R2 or Y1. |
