Abstract

Disclosed is A silver halide photographic light-sensitive material formed by coating at least one silver halide photographic emulsion layer on a reflective support having irregularities at random on the surface, wherein the intensity of Wiener spectrum of the reflective support at a spatial frequency of f cycles/mm given by the expression f=1120/CS is less than 90% of the geometric mean of the intensity at a spatial frequency of f/2 cycles/mm and the intensity at a spatial frequency of 2f cycles/mm when the coating speed for said silver halide emulsion layer is CS (m/minute). The silver halide photographic light-sensitive material according to the invention, has a proper gross and a high capability of depicting details of an image.
