  • Patent number: 7147996
    Abstract: Photographic silver halide materials containing an incorporated black-and-white developing agent can be quickly and simply processed using unique processing compositions and methods. In a “two-step” method, the exposed material is contacted with an alkaline activator solution followed by a fixing composition. In a “one-step” method, activation and fixing are combined using a single alkaline activator-fixing composition containing the fixing agent. None of the processing solutions include black-and-white developing agents. The photographic silver halide materials are preferably radiographic silver halide materials that have a reflective support and provide black-and-white images that can be viewed without a light box.

  • Patent number: 6187517
    Abstract: The present invention provides a gelatin-based aqueous-coatable overcoat for a photographic element that allows for appropriate diffusion of photographic processing solutions. The overcoat comprises 10 to 50% by weight gelatin and 50 to 90% by weight of hydrophobic particles (by weight of dry laydown of the entire overcoat) having an average diameter of 10 to 500 nm. A proteolytic enzyme is applied to the clement in reactive association with the overcoat layer. A photographic element according to one embodiment of the invention can be exposed and processed using normal photofinishing equipment, with no modifications, to provide an imaged element together with a protective, water-resistant layer.

  • Patent number: 6025118
    Abstract: A method of manufacturing an optical disc master from a glass substrate includes coating the substrate with a layer of photoresist, and applying an alkali-gel layer atop the photoresist. The coated substrate is then placed in an environment with a higher than normal humidity. The surface of the coated glass is selectively exposed to a beam of a writing laser, the exposure being controlled by digital information to be recorded on the disc. Exposed portions of the coated substrate experience a chemical reaction between the photoresist and the alkali material in the humid environment. Exposed portions are then developed and ablated thereby creating the pits and lands.
