Abstract
Disclosed is a color photographic element comprising a multilayered blue light sensitive record, a multilayered green light sensitive record, and a multilayered red light sensitive record, the red record comprising two or more layers of differing light sensitivity, the most light sensitive layer of the red record containing a red light sensitized first emulsion having at least one wavelength of peak absorption, and at least one of the two most light sensitive layers of the red record containing a red sensitized second emulsion, wherein the first emulsion exhibits, as measured at 0.2 density units above Dmin, at least one wavelength of peak absorption that is longer than the shortest wavelength of peak absorption of the second emulsion. The element provides an advantageous combination of speed and color rendition.
