Abstract

Abstract A silver halide photographic material is disclosed, having at least one hydrophilic colloid layer comprising a polyester support and having a polymer latex on at least one side of said polyester support, wherein both surfaces of said support are coated with a polymer layer comprising a copolymer containing from 50 to 99.5% by weight vinylidene chloride and wherein both polymer layers have a thickness of at least 0.3 µm. A method for treating the silver halide photographic material is also disclosed.
