Photographic recording process

Claim 2

A photographic recording process, in which a latent luminescence image is produced by the image-wise exposure of a photosensitive photographic recording material, wherein a photographic recording material comprising at least one layer which contains photosensitive silver halide and at least one compound capable of luminescence is exposed image-wise and developed by a silver halide developer to thereby produce a silver image and a latent luminescence image superimposed on the silver image, and the image information contained in the latent luminescence image is scanned photoselectively by a luminescence spectroscopic process and is recorded electronically in the form of monochromatic luminescence signals.

Claim 3

The recording process as claimed in claim 1, wherein a silver image is produced by image-wise exposure and development in at least one layer of a photographic recording material which contains in said layer photosensitive silver halide and a uniform distribution of a compound capable of luminescence, the luminescence of said compound capable of luminescence being weakened image-wise (in the event of excitation) by said silver image, the silver image is scanned by a beam of monochromatic light of a wavelength suitable for the excitation of the luminescence of said compound capable of luminescence, and the image information in the form of the luminescence thus excited is detected quantitatively by an opto-electronic transducer device, is converted into electronic image signals and is recorded electronically.

Claim 4

The process as claimed in claim 2, wherein the electronic image signals obtained from the opto-electronic transducer device are used for the initial control of an apparatus for the production of visible images.

Claim 5

The process as claimed in claim 2, wherein at least one spectral sensitizer is used as the compound capable of luminescence.

Claim 6

The process as claimed in claim 2, wherein after development and before scanning the silyer image by a beam of exciting light, the photographic recording material is treated with means for removing the remaining silver halide.

Claim 7

The process as claimed in claim 2, wherein a photographic recording material having an opaque substrate is used.

Claim 8

The process for electronically recording including the steps of first image-wise exposure and development of a photosensitive photographic recording material comprising at least three silver halide emulsion layers of a photographic recording material, said three silver halide emulsion layers differing in spectral sensitivity and each containing a uniform distribution of a compound capable of luminescence, each of said compounds capable of luminescence contained in one of said three silver halide emulsion layers differing from said compounds capable of luminescence contained in others of said three silver halide emulsion layers in that it is excited by exciting light from a different partial region of the spectrum, whereby a silver image is produced in each layer, and each of said silver images thus produced represents a color separation image corresponding to the spectral sensitivity of the respective layer; and then scanning each of said color separation images by a beam of monochromatic light of a wavelength suitable for the excitation of the luminescence of the compound capable of luminescence contained in the respective layer, and the luminescence of the compound capable of luminescence contained in each of said three silver halide emulsion layers being weakened image-wise by the silver image in said layer; and then detecting quantatively by an opto-electronic transducer device the image information of each color separation image in the form of the luminescence thus excited; converting the information into electronic image signals and recording electronically.

Claim 9

The process for electronically recording including the steps of first image-wise exposure and development of a photosensitive photographic recording material comprising at least three silver halide emulsion layers of a photographic recording material, said three silver halide emulsion layers differing in spectral sensitivity and each containing a uniform distribution of a compound capable of luminescence, each of said compounds capable of luminescence contained in one of said three silver halide emulsion layers differing from said compounds capable of luminescence contained in others of said three silver halide emulsion layers in that it is excited by exciting light from a different partial region of the spectrum, whereby a silver image is produced in each layer, and each of said silver images thus produced represents a color separation image corresponding to the spectral sensitivity of the respective layer; and then scanning each of said color separation images by a beam of monochromatic light of a wavelength suitable for the excitation of the luminescence of the compound capable of luminescence contained in the respective layer, and the luminescence of the compound capable of luminescence contained in each of said three silver halide emulsion layers being weakened image-wise by the silver image in said layer; and then detecting quantatively by an opto-electronic transducer device the image information of each color separation image in the form of the luminescence thus excited; converting the information into electronic image signals and recording electronically.

Claim 10

The process as claimed in claim 7, wherein the electronic image signals from each of the color separation images are useful for the initial control of an apparatus for the production of a monochromatic visible partial image of another color and a multi-colored image is produced by the combination of the differently colored partial images.

Claim 11

The process as claimed in claim 7 wherein color separation images of the primary colors blue, green and red are recorded by using a photographic recording material having a blue-, a green- and a red-sensitized silver halide emulsion layer.
