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, and (4) spectral sensitizing dye in the red recording layer units exhibits an overall half-peak absorption bandwidth of at least 50 nm bridging the green and red regions of the spectrum, with absorption at 560 nm being in the range of from 80 to 95 percent of maximum absorption, which is located in the spectral region of from 570 to 710 nm. When the images produced by the red recording layer units are printed as red images, the human eye sees the red component image as an improved reproduction of the red component of the original image.
