Silver halide color photographic material containing a yellow coupler and a mercapto compound

A silver halide color photographic material having at least one silver halide emulsion layer on a reflex support, wherein at least one of the silver halide emulsion layers comprises (i) silver halide grains containing at least 90 mol % silver chloride and having a silver bromide-rich region in the vicinity of at least one grain corner, but having an average silver bromide content of 15 mol % or less at the grain surface, wherein at least the silver bromide-rich region of the silver halide grains contains an iridium compound, (ii) at least one coupler represented by the following general formula (I):

• ##STR113## and (iii) at least one compound represented by the following general formula (II):
• ##STR114## wherein R.sub.1 represents an aryl group or a tertiary alkyl group;
• R.sub.2 represents a fluorine atom, an alkyl group, an aryl group, an alkoxy group, an aryloxy group, a dialkylamino group, an alkylthio group, or an arylthio group;
• R.sub.3 represents a group which can replace a hydrogen atom of a benzene ring;
• X represents a hydrogen atom or a group capable of being removed by a coupling reaction with an oxidation product of an aromatic primary amine developing agent;
• l represents an integer from 0 to 4, and when l is 2 or more, the R.sub.3 groups may be the same or different;
• Q represents a group of atoms necessary to complete a 5- or 6-membered hetero ring which may be fused together with a benzene ring;
• and M represents a hydrogen atom or cation.
