摘要:
Disclosed is a photographic element comprising a support bearing a blue light sensitive record containing at least three layers having different levels of light sensitivity arranged in the order slowest to fastest with the slowest layer closest to the support and the fastest layer closest to the light exposure source, wherein (a) all of the blue-sensitive layers are closer to the light exposure source than the layers sensitive to any other color; (b) the slowest blue light sensitive layer is at least 1.0 logE slower than the next fastest blue light sensitive layer when measured at a density of 0.15 above Dmin, and contains a particular type of cyan dye-forming development inhibitor releasing (DIR) coupler; and (c) all of the blue light sensitive layers other than the slowest blue light sensitive layer independently contain a certain type of yellow dye-forming DIR coupler. Embodiments of the invention provide improved color rendition without sacrificing blue density.
