ABSTRACT:
Disclosed is a silver halide photographic material which comprises a monodispersed polymer having an average grain size of from 1 to 10 .mu.m and variation coefficient of 0.10 or less and having a functional group which forms a covalent bond by reacting with an organic hardening agent or gelatin. Preferably, the polymer is a polymer obtained by polymerization by adding to a hydrophilic organic solution a high molecular weight dispersant which is dissolved in the hydrophilic organic solution and further adding at least one vinyl monomer which is dissolved in the hydrophilic organic solution but the polymer to be formed is precipitated from the hydrophilic organic solution. More preferably, the polymer contains 60 wt % or more of the repeating unit derived from methyl methacrylate and has a glass transition point of 60.degree. C. or more. The silver halide photographic material is excellent in antistatic property, transporting property, adhesion resistance, transparency, scratch resistance, graininess, drying property and mat pinholes.
