Abstract

Abstract This invention presents a light-sensitive silver halide color photographic material having at least two silver halide emulsion layers having sensitivities in different spectral regions on the same side of a support, at least one layer of the layers comprising at least two silver halide emulsion layers with different sensitivities, in which each of the at least two silver halide emulsion layers with different sensitivities contains at least one kind of substantially monodispersed silver halide crystals and at least one silver halide emulsion layer of the layers comprises substantially silver iodobromide containing 4 mole % or more of silver iodide, and further the iodine content in the emulsion layer having the highest sensitivity is higher than that of the emulsion layer having a sensitivity second to the highest. The light-sensitive silver halide color photographic material of this invention has a wide latitude of exposure and can be developed suitably without receiving influence from the processing time of color development.
