Abstract

in a highly or superhighly sensitive color photographic material having at least one highly or superhighly light-sensitive silver halide emulsion layer containing a color-forming coupler and silver iodobromide grains color-sensitized with a dye having at least one sulfo group or carboxy group, the silver halide emulsion grains having a mean grain size of larger than about 1 micron, the occurrence of fog due to pressure stimulus is prevented effectively by the incorporation of a high-boiling organic solvent having a boiling point of higher than about 175.degree. C at normal pressure in the silver halide emulsion layer in an amount of higher than about 20% by weight of the amount of binder present in the emulsion layer.
