| Zusammenfassung: | A high contrast photographic material comprises a support bearing a silver halide emulsion layer, is free from nucleating agents and has a silver:gelatin ratio above 1 wherein the emulsion layer comprises silver halide grains which are spectrally sensitised, and contains a density enhancing amine compound in the emulsion layer or an adjacent hydrophilic colloid layer, characterised in that the spectrally sensitised silver halide grains comprise a grain population sensitised to radiation of a particular wavelength region and one or more grain population(s) sensitised to radiation of a different wavelength region. |
