Abstract
The present invention is directed to a method of scanning silver-halide-containing color photographic and photothermographic film. In particular, the present invention comprises record shifting by means by employing at least one infrared dye in a color unit of the film, thereby forming at least one image record in the infrared. This expedient leads to the formation of high quality images, especially when scanning photothermographic elements in which the silver halide, metallic silver, and/or any organic silver salts have not been removed.
Claims16
A light-sensitive color photographic element for recording an image comprising a support and, coated on the support, a plurality of hydrophilic-colloid layers, comprising radiation-sensitive silver-halide emulsions and dye image-forming couplers, forming three image recording layer units for separately recording blue, green, and red exposures, wherein the dye-image-forming coupler in at least one the three image recording layer units consists essentially of an infrared dye-forming coupler for color image formation.
A light-sensitive color photographic element comprising a support and, coated on the support, a plurality of hydrophilic colloid layers, comprising radiation-sensitive silver-halide emulsion and dye image-forming couplers, forming three recording layer units for separately recording blue, green, and red exposures, wherein the dye image-forming couplers in the element consists essentially of yellow, magenta and cyan dye-forming couplers and a developing agent or precursor thereof that is capable of shifting the hue of the dye formed by the cyan dye-forming coupler to the infrared for color image formation.
A light-sensitive color photothermographic element for recording an image comprising a support and, coated on the support, a plurality of hydrophilic-colloid layers, comprising radiation-sensitive silver-halide emulsions and dye image-forming couplers, and forming three image recording layer units for separately recording blue, green, and red exposures, wherein the dye image-forming couplers in at least one of the three image recording layer units consists essentially of infrared dye-forming coupler for color image formation, wherein the infrared dye-forming coupler is capable of forming, in reactive association with an incorporated developing agent or precursor thereof, an infrared dye;
- and wherein the element comprises a blue light-sensitive layer unit having a magenta dye forming coupler, a green light-sensitive layer having a cyan dye-forming coupler, and a red light-sensitive layer having said infrared dye-forming coupler.
