  • Patent number: 8986924
    Abstract: A thiosulfate polymer composition includes an electron-accepting photosensitizer component, either as a separate compound or as an attachment to the thiosulfate polymer. The thiosulfate polymer composition can be applied to various articles, or used to form a predetermined polymeric pattern after photothermal reaction to form crosslinked disulfide bonds, removing non-crosslinked polymer, and reaction with a disulfide-reactive material. Such thiosulfate polymer compositions can also be used to sequestering metals.

  • Patent number: 6638696
    Abstract: This invention provides a display element comprising a support, a phosphorescent material, and at least one layer containing a silver halide emulsion, wherein the phosphorescent material is not excited upon exposure of the silver halide emulsion. It further provides methods of exposing and processing such display elements.

  • Patent number: 6586165
    Abstract: The present invention is a photographic element which includes, in order, a transparent support, at least one silver halide emulsion layer superposed on the support, optionally a white or diffuse reflective layer, and a processing-solution-permeable protective layer on the backside, which protective layer becomes water-resistant in the final product without lamination or fusing. The present invention is also directed to a method of making a photographic print involving developing the photographic element. The resulting print is viewed through the support, which provides protection against scratches and stains, while the polymeric overcoat provides water and stain protection to the reverse of the print where minor scratches or damage are not critical, since the image is not viewed from this side. Thus, this invention provides for a tough, stain resistant and transparent viewing surface and a stain resistant back side, which is permeable to processing solutions.

  • Patent number: 6572677
    Abstract: The present invention relates to the use of fine metal particles for the recovery of silver from a silver-bearing photographic waste solution. In particular, the metal particles are encapsulated in a hydrophilic colloid that allows for the permeability of water and silver ions. When contacted with the silver-bearing photographic waste solution, the hydrophilic colloid will imbibe water and swell. At the same time, the silver ions can permeate the colloid matrix and come into contact with the metal particles, preferably iron particles, at which point a metal—metal exchange reaction takes place.

  • Patent number: 6455240
    Abstract: A method of reducing the tendency toward formation of coating non-uniformities in the coating of multilayer photographic elements is disclosed. More particularly, the present invention involves the coating of a non-gelatin coating over a topmost gelatin layer in a photographic element. In one embodiment, a processing-solution-permeable overcoat is simultaneously coated with the emulsion layers onto a photographic substrate, which overcoat becomes water and stain resistant in the photochemically processed product. In the latter embodiment, the overcoat formulation comprises at least one water-dispersible hydrophobic polymer interspersed with a water-soluble polymer.

  • Patent number: 6432623
    Abstract: A method of processing a photographic imaging element to obtain a protective overcoat is disclosed, which overcoat provides, in the final product, resistance to fingerprints, common stains, and spills. More particularly, the present invention involves a processing-solution-permeable overcoat that becomes water and stain resistant in the photochemically processed product. The overcoat formulation comprises at least one water-dispersible hydrophobic polymer interspersed with a water-soluble polymer. During development or thereafter, before drying, the water-soluble polymer is removed to a significant extent. Subsequently, the imaged element is dried at an elevated temperature to facilitate coalescence of the overcoat to thereby provide enhanced stain resistance and water-resistance.

  • Patent number: 5888648
    Abstract: The present invention is a multi-layer film which has an improved composite structure for providing hermetic seals to packages manufactured in high speed packaging apparatus. The structure of the multi-layer film of the present invention includes a main substrate and a sealant layer. The sealant layer, in turn, includes two components, an intermediate layer which has the primary function of compliance during sealing, and a sealing layer which has the primary function of providing adhesivity to the completed seal. As a result of this invention, high strength hermetic seals can be provided to multi-layer films effectively and efficiently, and hermetic seals are provided with the ability to be peeled open without destruction of several layers of the film.
