A silver halide photographic light-sensitive material comprises a support and provided thereon, a hydrophilic colloid layer comprising a silver halide emulsion layer, wherein said support has a thickness of 70 to 120 .mu.m and Young's modulus of not less than 550 kg/mm.sup.2 and said hydrophilic colloid layer has a degree of swelling of not more than 80%, said degree of swelling being obtained by the following equation:

Silver halide photographic light-sensitive materials

A silver halide photographic light-sensitive material comprising a support bearing on both sides thereof a silver halide emulsion layer containing a silver halide emulsion comprising monodispersed and spectrally-sensitized silver halide tabular grains having an average aspect ratio of grain diameter to grain thickness of from not less than 2 to less than 8 and accounting for at least 70% of the total projected area of the grains contained in the silver halide emulsion and a method of preparing the silver halide emulsion are disclosed, wherein the silver halide emulsion is chemically sensitized in the presence of iodide-containing silver halide fine grains, thus chemically-sensitized emulsion having a value of 100 mV or less with respect to a silver electrode potential at 50.degree. C.

Silver halide photographic light-sensitive material and a method for
