Abstract:
A photographic recording process employing a film comprising at least one imaging layer comprising a light-sensitive silver-halide emulsion, binder, an incorporated developer or developer precursor, and at least one fluorophore capable of luminescence, which method in order comprises:(a) imagewise exposing the film in a camera; (b) thermally developing the film comprising heating said film to a temperature greater than 80Â° C. in an essentially dry process, such that the incorporated developer or a developer formed from a developer precursor in reactive association with the exposed silver-halide in the silver-halide emulsion forms a silver image and a fluorescent latent image, (c) detecting the fluorescent latent image in the film without desilvering or fixing the film by illuminating the film with a substantially monochromatic light of a wavelength suitable for the excitation of the luminescence of said fluorophore to produce a luminescent signal of a different wavelength band, the emitted light; and measuring the imagewise intensity of the luminescent signal to produce an electronic image record capable of generating an image in a hard or soft display element.
