PROCESS AND ELEMENT FOR OBTAINING A PHOTOGRAPHIC IMAGE

A photograhic image is formed with silver halide emulsions by using optically unsensitized light sensitive (coarse) silver halide grains. Optically (or spectrally) sensitized fine grains (or crystals or particles), - especially light insensitive or Lippmann silver halide grains-, can be reactively a...

Summary:A photograhic image is formed with silver halide emulsions by using optically unsensitized light sensitive (coarse) silver halide grains. Optically (or spectrally) sensitized fine grains (or crystals or particles), - especially light insensitive or Lippmann silver halide grains-, can be reactively associated with optically (or spectrally) unsensitized light sensitive (coarse) silver halide grains to get a combination of Spectrally Sensitized Fine Grains with Spectrally Unsensitized Light Sensitive or Coarse Grains, - especially Tabular Grains -, which can be imagewise exposed (to the light absorbed by the dye sensitizer adsorbed on the surface of such fine grains) and developed with substantially the same sensitivity of the light sensitive optically sensitized (coarse) silver halide grains.
