    摘要: A silver halide photosensitive material comprising a support, a silver halide photosensitive layer, and a protective layer formed on said support. The protective layer is essentially composed on a plurality of non-photosensitive hydrophilic colloidal layers at least one of which contains oil particles. The outermost layer of the hydrophilic colloidal layers contains a matting agent in the form of colloidal particles and has a thickness of not more than one fourth of the average size of the matting agent particles and wherein the density of the oil particles in said outermost layer does not exceed 0.2 by volume of the binder, and that of the oil particles in the protective layers other than the outermost layer is in the range of 0.1 to 0.8.
