Abstract:
A dye-forming photothermographic element comprises in a binder, in reactive association,(a) photographic silver halide,(b) an image forming combination comprising(i) a reducible organic silver salt with(ii) a reducing agent selected from the group consisting of p-phenylenediamine, p-aminophenol, sulfonamidophenol, sulfonamidoaniline and hydrazone developing agents, and(c) a coupler which is capable of forming an image dye by reaction with the oxidized form of the reducing agent.In such a photothermographic element improvements are provided wherein the coupler has attached to the carbon atom at the coupling position either (A) a group --S--Dye, wherein Dye represents an image dye, or a blocked or shifted form thereof, and any necessary linking group, or (B) a moiety --S--Z, wherein Z represents atoms linking the sulfur atom to another position in the coupler. The exposed dye-forming photothermographic element is capable of forming a dye image by merely heating the element. The dye-forming photothermographic element can be a diffusion transfer photothermographic element in which the image dye formed upon heating the exposed element is capable of being transferred to an image receiver.

Abstract:
A method of providing an image in an imagewise exposed photographic silver halide material comprising at least one silver halide emulsion layer, which method comprises developing the silver halide and fixing the remaining silver halide by contacting it with a molten composition comprising a silver halide complexing agent which is present in sufficient amount to render the silver halide substantially clear. The photographic silver halide material may comprise at least one silver halide emulsion layer on a support wherein the material also comprises a layer of a composition comprising a silver halide complexing agent which is liquefiable by heat and which, when molten, is in reactive association with the silver halide. The image formed may be scanned to produce an electronic rendition of the image.

Abstract:
A method of making a random color filter array layer which comprises dispersing in an aqueous medium a water immiscible oily liquid having dyes and/or pigments dissolved or dispersed therein to form colored droplets and mixing the resulting dispersion with one or more other dispersions of different colors in a continuous aqueous phase having a film forming polymer dissolved therein and coating the resulting mixture onto a support layer. The color filter array is useful in image capture devices including digital cameras, scanners and photographic film.
Abstract:
The method relates to a method comprising providing a coating of a cross-linkable polymeric substance on a transparent or translucent substrate, applying a pattern of cross-linker to said coated substrate by ink jet printing to cross-link said polymeric substance in the pattern of the crosslinker, washing the coated substrate to remove cross-linkable polymer in the area not having the pattern of cross-linker applied thereto, and applying a contrasting color layer to the hardened cross-linked polymeric material.
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 that produce images of the same hue upon processing (e.g., lacking an incorporated dye-forming coupler). A first interlayer overlies the emulsion layer unit nearest the support for transmitting to it imagewise exposing radiation this emulsion layer unit is intended to record and for absorbing after photographic processing scanning radiation within at least one wavelength region. A second interlayer underlies the emulsion layer unit farthest from the support for transmitting to the underlying emulsion layer units exposing radiation they are intended to record and for absorbing after photographic processing scanning radiation within at least one wavelength region. The imagewise exposed photographic element is photographically processed to produce a reflective image in each of the emulsion layer units and is reflection scanned utilizing the absorption of the first and second interlayers to provide the image information in two of the emulsion layer units. The photographic element is scanned through the interlayers and all of the emulsion layer units to provide a spectrally undifferentiated third record of the combined images in all of the emulsion layer units. The first, second and third records are compared to obtain separate blue, green and red exposure records. In the photographic elements of the invention the interlayers remain or become light absorbing after photographic processing.
Abstract:
An improved photographic silver halide element comprises a support, and an emulsion layer unit containing one or more photographic silver halide emulsions sensitized to the same spectral region and, adjacent each side of the emulsion layer unit, a layer substantially free of active silver halide containing an image modifier which is a compound capable of imagewise releasing an image-modifying compound on silver halide development wherein at least one of the layers contains a dye image-forming coupler. Such a layer arrangement enables greater control of the emulsion layer's response to oxidized developer generated upon processing.
