Abstract
A silver halide photographic light-sensitive material having on a support at least one light-sensitive silver halide emulsion layers and at least one light-insensitive upper layers on the emulsion layer, in which at least one of said light-insensitive upper layers contains a polymer latex having a glass transition point of at least 20.degree. C. and the said at least one light-insensitive upper layer and/or at least one other of said at least one light-insensitive upper layer(s) contains a polymer latex having a glass transition point of lower than 20.degree. C. In the silver halide photographic light-sensitive material, at least one of the light-insensitive upper layers can also have a melting time which is longer than that of the light-sensitive silver halide emulsion layer. The silver halide photographic light-sensitive material has high sticking resistance and improved layer strength under low humidity conditions.
