    Abstract: Rapid development of silver bromoiodide color negative photographic films and formation of high quality negative images suitable for scanning to produce display images of excellent quality is made possible by a novel developer solution composition and method of development. The solution is characterized by containing, in addition to the color developer compound and conventional photographic developer solution components, a water soluble pyrrolidone polymer, a high concentration of sulfite ion and a low concentration, or the absence of, bromide ion. In the novel method the developer composition contacts the exposed film at elevated temperature, e.g., 40 to 66° C., for a short development time, e.g., 20 to 90 seconds. The developed image has image quality suitable for scanning and digital manipulation to produce a digital record for forming a color display image of high quality.

  • Patent number: 6190844
    Abstract: High performance radiographic films exhibit visually adaptive contrast when imaged in radiographic imaging assemblies comprising an intensifying screen on both sides. These films have at least two silver halide emulsions (preferably tabular grains) on each side of a film support, and the emulsion closest to the film support on each side includes chemistry to control crossover. In addition, the films can be rapidly processed to provide the desired image whereby the upper scale contrast is at least 1.2 times the lower scale contrast. Thus, dense objects can be better seen at the higher densities of the radiographic image without any adverse sensitometric changes in the lower scale densities. These films have greater dynamic range that allows them to be scanned and digitized to correct for under- or over-exposure.

A layer which does not contain any hydroquinones but contains a ultraviolet absorbent is provided above the cyan coupler-containing silver halide emulsion layer having a high chloride content, while below the cyan coupler-containing emulsion layer is provided another layer containing hydroquinones but not containing any ultraviolet absorbent. These materials are processed rapidly with a color developer under a reduced replenishment condition, wherein the amount of a color developer replenished is controlled to below 120 ml/m.sup.2, to provide color images fast to light and free from bluish unevenness in the edge part thereof.

  • Patent number: 5350664
    Abstract: A method is disclosed of obtaining from an imagewise exposed photographic element separate records of the imagewise exposure to each of the blue, green and red portions of the spectrum comprising photographically processing an imagewise exposed photographic element comprised of a sequence of superimposed blue, green and red recording silver halide emulsion layer units at least two of which produce images of the same hue upon processing (e.g., lacking an incorporated dye-forming coupler), and obtaining separate blue, green and red exposure records from the photographic element. The photographic element is additionally comprised of, interposed between the two emulsion layer units, an interlayer unit for transmitting to the emulsion layer unit of the two units which is nearer the support, electromagnetic radiation that this emulsion layer unit is intended to record and capable, after processing, of reflecting electromagnetic radiation within at least one wavelength region.

  • Patent number: 5262286
    Abstract: The invention is generally accomplished by providing a reflection print material having thereon sensitized silver halide containing layers and at least one layer comprising at least one insoluble colored tint, wherein said at least one tint changes the color of said material to be less yellow. In a preferred form, it has been found that a combination of two tints is preferred to provide ready adjustment of the tinting to match the yellowing characteristics of the print material.
