摘要： A high-speed color negative photographic material which comprises, a support having provided thereon, at least one red-sensitive silver halide emulsion layer, at least one green-sensitive silver halide emulsion layer and at least one blue-sensitive emulsion layer, and is designated so as to acquire a specific photographic sensitivity (defined in detailed description of the invention) of 800 or above, and has a combined total of silver coverages ranging from 3.0 g/m.sup.2 to 9.0 g/m.sup.2 so as to minimize an increase in fog, a decrease in photographic speed and deterioration in granularity, which heretofore have occurred in high-speed photographic materials during long-range storage before used. In addition, the present photographic material enables enhancement of pressure resistance and processing efficiency.
