Silver halide color photographic material and method for forming color image

A method for forming a color image, which comprises exposing a silver halide photographic material to light by a scanning exposure system taking a shorter exposure time than 10.sup.-4 second per pixel to prepare an exposed image, and color developing the exposed image;

• wherein the silver halide color photographic material comprises a support having provided thereon photographic constituent layers comprising (i) at least three kinds of silver halide emulsion layers different in color sensitivity, each containing a yellow color-forming coupler, a magenta color-forming coupler and a cyan color-forming coupler, respectively, and (ii) at least one light-insensitive layer,
• wherein the photographic constituent layers comprises at least one layer containing silver chloride grains or silver chlorobromide grains having a silver chloride content of not less than 90 mol %, the silver chloride grains or silver chlorobromide grains having a silver chloride content of not less than 90 mol % being sensitized by at least one compound selected from the group consisting of a gold compound, a selenium compound and a tellurium compound;
• and the photographic constituent layers comprises at least one layer containing at least one compound represented by formula (I) ##STR136## wherein R.sup.1 and R.sup.3 each represents an electron withdrawing group having a Hammett substituent constant .theta..sub.p of 0.3 or more;
• R.sup.2 and R.sup.4 each represents an alkyl group or an aryl group;
• L.sup.1 to L.sup.5 each represents a methine group, with the proviso that at least one of L.sup.1 to L.sup.5 has a substituent group;
• M.sup.1 represents a hydrogen atom, or an atomic group or metal atom to be a monovalent cation.
