Abstract
A single-side coated silver halide photographic film material has been disclosed, said film material comprising a support, at least one light-sensitive emulsion layer and a substantially light-insensitive protective hydrophilic colloid layer farther away from said support than said emulsion layer, wherein said emulsion layer contains a silver halide emulsion rich in silver bromide with cubic crystals having an average numerical diameter in the range from 0.4 up to 0.8 &mgr;m, wherein at least 95 mole % of bromide ions are present, and wherein said hydrophilic colloid layer or another substantially light-insensitive hydrophilic colloid layer essentially comprises a hydrazide represented by the general formula (I) having a silver halide adsorbing group or a masked silver halide adsorbing group; besides a method for forming a diagnostic image comprising the steps of contacting said photographic film material with an intensifying screen, forming a film/screen assembly, and exposing said assembly to X-ray radiation with an energy lower than or equal to 70 kVp, and processing said film material during a time of 90 seconds or less in a processing cycle following the steps of developing, fixing, rinsing and drying, and wherein the developing proceeds in a radiographic developer composition essentially comprising a hydroquinone and a phenidone (a 1-phenyl-3-pyrazolidine-1-one compound) as a developing agent and a heteroatomic nitro-indazol.
