  • Single-side coated silver halide photographic film material having reduced tendency to curl
    Patent number: 6573036
    Abstract: A single-side coated light-sensitive silver halide photographic film material has been disclosed, having on one side of a subbed support, one or more light-sensitive silver halide emulsion layer(s) overcoated with an outermost protective layer; and, at the other side of said support, a backing layer, covered with a protective outermost layer, characterized in that at least said backing layer is provided with a layer wherein, besides a cross-linked or cross-linkable first binder an organic component free from cross-linking upon reaction with a hardener is present as a second binder having a low molecular weight.
    Type: Grant

  • Photographic silver halide photographic material for mammography
    Patent number: 6573019
    Abstract: A radiographic film material has been described for recording medical diagnostic images of soft tissue through exposure to light, emitted by a single intensifying screen, after having been subjecting to exposure with X-rays, emitted from an X-ray generating device with a tube voltage of 20 kV to 40 kV, and processing, including development, fixing and drying, within a time of 120 (and more preferably 90) seconds or less, wherein said film is comprised of a transparent film support, front and back major faces and an image-forming portion for providing, when imagewise exposed by light emitted by said intensifying screen and processed, an average contrast or gradient in the range from 3.0 up to 4.5, measured over a density above fog in the range of from 0.25 to 2.
