摘要:
A light-sensitive silver-halide color photothermographic element comprises a typically magenta dye-forming pyrazolone coupler in the cyan record by rendering the hue of the resultant dye a cyan hue. The use of certain para-phenylenediamine developers, for example, containing a substituent group in both the 2- and 6-positions (ortho, ortho') relative to the coupling nitrogen, along with selected magenta dye-forming couplers, when oxidized, yield cyan dyes with certain couplers, resulting in the superior non-hue characteristics of magenta couplers in the cyan layer. By means of the present invention, light sensitive color photothermographic elements can form image dye records of consistent density forming ability and consistent stability in all three color records. Also disclosed is a method of processing such a color photographic element.
摘要:
The present invention is directed to a photothermographic element comprising at least one imaging layer with a pyrrolotriazole coupler and a developing agent, or precursor thereof, the combination of which is capable of forming an image record in the infrared region of the light spectrum in response to a selected hue of visible light. 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. Also disclosed is a method for photothermographically forming a developed image comprising an infrared image record.
摘要:
The present invention is directed to a method of scanning silver-halide-containing color photographic and photothermographic film. In particular, the present invention comprises a photographic element comprising at least one infrared imaging dye-forming agent in a blue-sensitive color layer of the element, thereby forming at least one image record in the infrared region of the imagewise exposed and developed element. This expedient leads to the formation of high quality images when scanning photographic elements in which the silver halide, metallic silver, and/or any organic silver salts have not been removed.

摘要:
This invention involves the use of ionic liquids as coupler solvents in a color or monochrome photothermographic system. The presence of an ionic liquid can increase the amount of density or dye formed. The ionic liquid may be combined with other coupler solvents.
摘要:
This invention involves dispersions comprising ionic liquids and a non-ionic surfactant, optionally further comprising a photographically useful compound such as a dye-forming coupler. Such dispersions form coatings that are relatively free of physical defects, and show reduced problems such as crystallization of components like the couplers or ion pairs.
