Implants prepared according to the process of the present invention have comparable oxidation resistance and superior wear performance compared to unirradiated ultrahigh molecular weight polyethylene.

  • Publication number: 20030036026
    Abstract: The invention provides black and white silver halide material for optical contact copying, comprising: at least one photographic emulsion layer including a silver-halide-containing matrix in which the matrix includes a polymer and a hydrophilic binder, wherein the ratio of the weight of silver in the emulsion layer to the weight of polymer in the emulsion layer per unit area is less than 2.0. The photographic material is suitable for use in optical contact copying providing reduced contact gain compared to that provided by conventional photographic material.
