ABSTRACT:
A silver halide photographic material has provided on a support a non-light-sensitive surface layer which contains an organic polymer represented by formula (I) and having a mean grain size of 1.0 .mu.m or more, the polymer being produced by suspension polymerization: ##STR1## wherein A is a repeating unit obtained by polymerization of at least one monomer having two or more copolymerizable ethylenic unsaturated groups; B is a repeating unit obtained by polymerization of at least one monomer having one copolymerizable ethylenic unsaturated group; and x, y and z each represents a weight percentage, x is a number of from 1 to 40, y is a number of from 30 to 99 and z is a number of from 0 to 65. The material has good vacuum contact adhesiveness in contact exposures, and the transparency of the processed material is good.
