Abstract (en)
[origin: EP0557785A1] The present invention provides a photographic film assembly which comprises coated on a sub-coated cellulose triacetate or cellulose acetate-butyrate base at least one gelatino silver halide emulsion layer wherein the silver halide emulsion layer which is closest to the base comprises from 1 to 30% by weight of the gelatin in the emulsion layer, a latex polymer whose glass transition temperature does not exceed 30 DEG C and which to a copolymer of an ethylenically unsaturated monomer containing an aromatic moiety, with an acrylate ester monomer. The latex polymer may also contain additional ethylenically unsaturated monomers. Preferably the amount of latex present in the silver halide emulsion layer is from 2 to 10% by weight of the gelatin in the layer.
