    摘要： A silver halide photographic light-sensitive material having at least one light-sensitive emulsion layer containing surface latent image-type silver halide grains, coated on a reflective support, in which said at least one emulsion layer contains regular crystal grains of silver chloride or silver chlorobromide having a mean silver chloride content of 80 mol % or more on the basis of the total silver halide grains contained therein and substantially does not contain silver iodide, and in which a colloidal silver-containing layer is located adjacent to said emulsion layer, wherein at least one of said colloidal silver-containing layer, said emulsion layer and an interlayer therebetween contains at least one mercaptoazole compound. The material is, after having imagewise exposed, processed with a color developer within 90 seconds. The material forms an image with excellent sharpness and whiteness.

    摘要： A photographic silver halide emulsion containing a yellow color forming coupler, in which one hydrogen atom of an active methylene group is replaced by a 2,5-dioxo-1-imidazolidinyl group, in which a nitrogen atom at 3-position and a carbon atom at 4-position are connected to form a ring through a divalent aliphatic radical, a photographic element containing the emulsion and a method for forming color photographic images which comprises developing the image-exposed photographic silver halide emulsion with a primary aromatic amino developing agent. These yellow color forming couplers have a high coupling reactivity as well as no adverse effect on the bleaching of developed silver and thus they are suitable for use in rapid processing type color photographic materials.
