Zusammenfassung:PROBLEM TO BE SOLVED: To obtain a color photographic element having high sensitivity and less liable to lower image sharpness. SOLUTION: The color photographic element includes a transparent film substrate and blue, green and red recording layer units coated on the substrate. In the photographic element, each image dye exhibits at least 25 nm half-width of an absorption peak not occupied by dyes other than the dye. The red recording layer unit is divided into at least two hydrophilic colloidal layers containing red sensitized silver halide grains and silver halide grains having the maximum sensitivity are present in a hydrophilic colloidal layer disposed in such a way that the layer first receives radiation for exposure. Red light scattering silver halide grains not containing an adsorbed spectral sensitizing dye, having 0.05-0.7 μm equivalent circular diameter and oriented at random are introduced into only the hydrophilic colloidal layer disposed in such a way that the layer first receives radiation for exposure by 0.01-0.2 g/m2 coating weight on the basis of the amount of silver. The silver halide grains of the blue, green and red recording layer units contain >50 mol% bromide.
