ABSTRACT:
A silver halide color photosensitive material, which has: at least each one layer of yellow-, magenta- and cyan-color-forming photosensitive silver halide emulsion layers on a reflective support, and at least one non-light-sensitive non-color-forming hydrophilic colloidal layer; wherein at least one of the photosensitive silver halide emulsion layers contains a silver halide emulsion containing 90 mol % or more of silver chloride, and a compound having a repetitive unit of formula (I) is contained:wherein R1is —OR, —SR or —N—R(—R′), where R and R′ are a hydrogen atom, or an alkyl, aryl, aralkyl, cycloalkyl or heterocyclic group, or R and R′ may form a saturated carbon ring or a heterocycle; R2and R3are a hydrogen atom or an alkyl group; Y1and Y2are a polymethylene, arylene or cycloalkylene group; Z is —O—, —SO2— or —CH2—; and m is 0 or 1.
