  • Patent number: 6570034
    Abstract: The present invention relates to a novel blocked phenylenediamine developer useful, in reactive association, for enabling, on development, a non-magenta color, for example a cyan color, from a dye-forming coupler. In one embodiment, the developer has the property that the dye color formed with the coupler is distinctly different from the color formed by the same coupler with an oxidized form of the conventional developer 4-(N-ethyl-N-2-hydroxyethyl)-2-methylphenylenediamine. The invention is also directed to a light-sensitive silver-halide color photographic element comprising the blocked developing agent according to the present invention.

  • Publication number: 20030087206
    Abstract: An image forming assembly and method utilizes a laminate processing sheet. The laminate processing sheet is applied on an emulsion side of an exposed photosensitive film which includes sprocket holes along opposing edges. In a first feature of the present invention, a width of the laminate processing sheet is confined to an image area between the opposing sprocket holes, so as to reduce or eliminate the possibility of processing marks in or around an area of the opposing sprocket holes. In a further feature of the present invention, an absorbing sheet can be applied to the backside of the photosensitive film, to absorb any excess processing or wetting solution that is applied to the photosensitive film. This also aids in reducing or eliminating unwanted processing marks at the sprocket holes or an area in the vicinity of the sprocket holes.

  • Patent number: 6531271
    Abstract: A light-sensitive silver-halide color photographic element comprising at least two different chromogenic couplers including, in reactive association, a multifunctional coupler and a developer precursor that liberates a developing agent enabling cyan color from the multifunctional coupler on development, wherein the multifunctional coupler has the property that it is capable of forming a distinctly colored dye with an oxidized form of the developer 4-(N-ethyl-N-2-hydroxyethyl)-2-methylphenylenediamine. In one embodiment, the multifunctional coupler has the property that it is capable of forming a distinctly colored magenta dye with an oxidized form of the developer 4-(N-ethyl-N-2-hydroxyethyl)-2-methylphenylenediamine. By means of the present invention, light-sensitive color photothermographic elements can form yellow, magenta and cyan dye records of consistent density forming ability and consistent stability in all three color records.

  • Patent number: 6517981
    Abstract: 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.

    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.

  • Patent number: 6402398
    Abstract: A photographic material processing apparatus and method provides for a homogeneous application of processing solution which leads to homogeneous development. The apparatus utilizes a spreader member in the form of, for example, a spreader bar that applies a limited quantity of developer solution to photographic material such as imagewise exposed film. A pressure member in the form of, for example, a weighted roller or spring-loaded roller acts a squeegee roller and improves contact of the film with a support and/or a heating source. A roller arrangement which includes at least the spreader member and pressure member is configured to enable multiple contacts of the spreader member and pressure member with the photographic material to aid in the agitation of the applied developer solution. In a further embodiment, an additional member in the form of, for example, a mixer member can be utilized to further agitate the applied solution.

  • Patent number: 6369873
    Abstract: A thermal processing kiosk for processing thermal film provides multiple processing options for a user. The kiosk includes a user control in the form of a touchscreen to permit the user to enter processing instructions and/or information. The thermal kiosk is adapted to accept exposed film for processing and printing in accordance with the processing instructions. In one feature of the invention, a user can prepay for processing of the film at the time of purchase of the film. The pre-paid status can be provided on the film by a marker or identifier on the cassette or the film. This helps to simplify the user interaction at the kiosk when the user submits the exposed film to the kiosk for processing. In further features of the invention, the processing flow in the thermal kiosk can be adapted to provide for rapid processing and the kiosk can include a display to permit a user to preview images prior to printing.

  • Patent number: 6361225
    Abstract: An apparatus can be used to process photographic silver halide materials in an “almost dry” format. This apparatus includes means for supplying the photographic material as well as photochemical delivery articles and means for providing the chemicals for photochemical reaction and image formation. The apparatus can also include heating means for speeding up the reaction, scanning means and solution applicators at various stations. The delivery articles can be laminated or other wise contacted with the imaged photographic materials on the silver halide emulsion side allowing photochemicals to diffuse into and out of the materials for the desired chemical reactions.
