  • Patent number: 6348293
    Abstract: A radiographic film material is described including a transparent film support having first and second major surfaces coated with a subbing layer, optionally overcoated with an antihalation undercoat. Coated adjacent on each side of the film support is a light-sensitive silver halide emulsion overcoated with a protective antistress layer. The emulsion layer has chemically and spectrally sensitized {111} tabular hexagonal grains or crystals, having silver iodide in an amount of at most 3 mole %, based on silver, covering at least 50% of the total projective surface of all grains, having an average grain thickness of less than 0.30 &mgr;m. The antistress layer, or the optional antihalation undercoat or both includes a N-amino mercapto-triazole compound containing one or more alkali soluble group(s). A radiographic screen/film combination is also described including the film material.

  • Patent number: 6238853
    Abstract: A method of processing has been described for a light-sensitive black-and-white silver halide photographic material comprising the distinct steps of developing, fixing, rinsing and drying, wherein during said processing said developer comprises, besides one or more developing agent(s), one or more agent(s) preventing oxidation thereof and agent(s) providing pH buffering in running equilibrium conditions during said processing, at least one agent preventing silver dissolution and at least one silver complexing agent, characterized in that said agent preventing silver dissolution, if present in an amount of 50 mg/l of developer, makes silver content of the developer decrease in an amount of more than 50% versus in the absence thereof, without loss in speed in an amount of more than 0.10 log Exposure after processing in said developer composition; said silver complexing agent makes silver content of the said developer increase in an amount of more than 1 mg per liter per mmole of said complexing agent.

  • Patent number: 6238854
    Abstract: A black-and-white silver halide developer composition has been disclosed comprising, besides one or more developing agent(s), agent(s) preventing oxidation thereof and agent(s) providing pH buffering, at least one silver complexing agent, characterized in that said silver complexing agent has a silver complexing stability ratio of at least 70% and, besides said silver complexing agent, at least one agent preventing silver dissolution characterized in that said agent preventing silver dissolution, if present in an amount of 50 mg/l of developer, makes silver content of the developer decrease in an amount of more than 50% versus in the absence thereof, without loss in speed in an amount of more than 0.10 log Exposure after processing in said developer composition.
