摘要:
An object of the present invention is to provide a silver halide photographic material having improved antiblocking property without deterioration of film brittleness and image quality due to addition of a polymer latex.A silver halide photographic material having at least one silver halide emulsion layer and at least one nonsensitive protective layer on a support, in which the nonsensitive protective layer contains polymer grains represented by the following General Formula (1) in a proportion by weight of 5 to 300% to a hydrophilic colloid as a binder, and the polymer grains have a mean grain diameter of at most 0.1 .mu.m,--(A).sub.x --(B).sub.y --(C).sub.z -- General Formula (1)wherein A is a repeated unit derived from an ethylenically unsaturated monomer containing carboxyl group, B is a repeated unit derived from a cross-linking monomer having at least two ethylenically unsaturated groups and C is a repeated unit derived from another ethylenically unsaturated monomer than those of A and B, x, y and z are copolymerization ratios, x being 1 to 50 weight %, y being 0 to 20 weight % and z being 30 to 85 weight %, and x+y+z=100.
