Abstract
A photographic material including a support having thereon photographic component layers including a red-sensitive emulsion layer containing a cyan coupler, a green-sensitive emulsion layer containing a magenta coupler and a blue-sensitive emulsion layer containing a yellow coupler. At least one of these silver halide emulsion layers contains a diffusible DIR compound, wherein the total dry-thickness of the photographic component layers is not greater than 16 .mu.m and the total silver halide content of the silver halide emulsion layers is not more than 6.5 g/m.sup.2 of silver. A colloidal layer, formed in a position farther from the support than the silver halide emulsion layer which is farthest from the support, contains substantially non-light-sensitive fine grain silver halide grains.
