ABSTRACT:
A silver halide color photographic material having photographic constituent layers on a support, said photographic constituent layers comprising at least 3 kinds of silver halide emulsion layers different in color sensitivity and each containing a coupler producing a yellow color, a magenta color, or a cyan color and at least one light-insensitive layer, in which a silver halide emulsion contained in at least one layer of said photographic constituent layers comprises silver chloride grains or silver chlorobromide grains having a silver chloride content of 90 mol % or more sensitized by at least one compound selected from the group consisting of a gold compound, a selenium compound and a tellurium compound and at least one layer of said photographic constituent layers contains a pentamethineoxonol dye containing a substituent group at the methine chain, whereby the silver halide color photographic material exhibits excellently rapid processing performance, high purity whiteness in the white background of a finished color photograph, high sensitivity, and a small fluctuation in color forming density despite time elapsing from exposure until development when the color photographic material is exposed to light under the circumstances of high humidity.
