A photographic silver halide emulsion containing silver halide grains having an average grain size of from 0.3 to 3.0 microns in diameter as a light sensitive element in a dispersing medium and additionally containing super fine grains of silver halide having an average grain size of less than 0.2 microns in diameter is disclosed.

Process for improving image-sharpness of photographic silver halide

A color photographic light-sensitive material which comprises a support having thereon at least a red-sensitive silver halide emulsion layer, a green-sensitive silver halide emulsion layer, a yellow filter layer and a blue-sensitive silver halide layer, in which the green-sensitive layer comprises a first green-sensitive silver halide emulsion layer and a second green sensitive silver halide emulsion layer and the relative positionwise relationship of each layer is in the order of the red-sensitive silver halide emulsion layer, the first green-sensitive silver halide emulsion layer, the yellow filter layer, the blue-sensitive silver halide emulsion layer and the second green-sensitive silver halide emulsion layer from the support.

Color photographic light-sensitive material

An incorporated-dye image forming coupler type multilayer multicolor photographic material comprising a support having thereon at least two silver halide emulsion layers each of which is sensitive to a different spectral wavelength range, with the silver halide emulsion layer which first receives light at image exposure being positioned so that the light is received through a non-sensitive hydrophilic layer containing a semidiffusible color coupler which forms a dye image having a substantially complimentary color to the sensitive wavelength range of the silver halide emulsion layer first receiving light at image exposure and which has a diffusion coefficient of from about 0.25 to 0.80 as defined by the relationship
