| Zusammenfassung: | A high contrast photographic material comprises a support bearing a silver halide emulsion layer which material is free from nucleating agents and has a silver:gelatin ratio above 1 characterised in that the emulsion layer comprises both silver halide grains which are spectrally sensitised and silver halide grains which are not spectrally sensitised, and contains a density enhancing amine compound in the emulsion layer or an adjacent hydrophilic colloid layer. |
