ABSTRACT:
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.
