  • Publication number: 20070141259
    Abstract: An article comprising a substrate and a patterned electrically conductive metal phase, wherein the electrically conductive metal phase is selectively deposited on the substrate via sequential or simultaneous ink jetting of combinations of a reducible soluble metal salt, a reduction catalyst and a reducing agent. On substrates having layered structures, the selectively deposited electrically conductive metal phase is intertwined with the substrate microstructure. A method of forming the same is also provided. In a particular embodiment of the method, the selective deposition of the electrically conductive phase onto the substrate comprises a first jetting of a composition comprising the reducible soluble metal salt and the reduction catalyst in a predetermined area followed by a subsequent jetting of a composition comprising the reducible metal salt and the reducing agent over the same predetermined area.

  • Publication number: 20050046734
    Abstract: Cartridge and camera systems are provided that have a cartridge with a photosensitive element having an exposure surface and a housing having a storage area for storing the photosensitive element and an opening adapted to permit transport of the photosensitive element from a storage position within a housing to exposure position outside of the housing. A micro-lens array is joined the housing and positioned to confront the exposure surface when the photosensitive element is in the exposure position.

  • Patent number: 5399472
    Abstract: A silver halide emulsion is disclosed including a blend of a first image dye-forming coupler which does not intrinsically inhibit development of silver halide, and a second image dye-forming coupler which intrinsically inhibits development of silver halide. The intrinsically development inhibiting couplers are defined empirically versus a standard coupler. For purposes of this invention DIR couplers are not considered intrinsically development inhibiting couplers. Photographic elements and methods for developing images using the coupler blends are also disclosed.
