Summary:PROBLEM TO BE SOLVED: To provide a color photographic silver halide material suitable for digital exposure and analog exposure and characterized by sharp gradation and stable latent image quality independent of exposure time. SOLUTION: The color photographic silver halide material capable of forming a negative when developed, having silver halide, at least 95 mol% of which comprises AgCl, including at least one photosensitive silver halide emulsion layer and containing at least one of compounds of the formula [IrClnF6-n]2-M2+ (I) [where (n) is 0 or an integer of 1-6 and M2+ is 1 or 2 cations having 2 positive charges in total], the formula [Fe(CN)6]m-Mm+ (II) [where (m) is 2 or 3 and Mm+ is 1-3 cations having 2 or 3 (m) positive charges in total] and formula (III) [where (o) is 0, 1 or 2 and R is alkyl, aryl or aralkyl] in the silver halide is characterized by clear contrast and a stable latent image independent of exposure time under scanning exposure or in analog exposure.
