  • Patent number: 6190847
    Abstract: A color negative silver halide photographic element is disclosed that is capable of producing images that, when converted to electronic form and then converted to a viewable form, exhibit reduced granularity. The photographic elements contain blue, green and red recording layer units capable of forming spectrally differentiated dye images. The layer units are substantially free of masking coupler, each exhibit a dye image gamma of less than 1.5 and an exposure latitude of at least 2.7 log E. Greater than 50 mole percent of development inhibitor compound in at least one of the layer units exhibits a diffusion factor of less than 0.4.

  • Patent number: 6146818
    Abstract: A color negative film is disclosed capable of producing dye images suitable for digital scanning comprised of a support and, coated on the support, a series of hydrophilic colloid layers including at least two red recording emulsion layer units capable of forming a dye image of a first hue, at least two green recording emulsion layer units capable of forming a dye image of a second hue, and at least one blue recording emulsion layer unit capable of forming a dye image of a third hue, wherein, (1) the series of hydrophilic colloid layers include the following sequence, starting with the layer unit coated nearest the support: (a) a slower speed red recording layer unit, (b) a slower speed green recording layer unit, (c) a faster speed red recording layer unit, and (d) a faster speed green recording layer unit; (2) colored masking couplers are absent from the recording layer units; (3) tabular grain emulsions sensitized to the green and red are employed in the green and red recording layer units, respectively, a
