Abstract:
A photographic element comprising a support bearing a blue light sensitive record containing at least three yellow dye-forming 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 log E slower than the next fastest blue light sensitive layer when measured at a density of 0.15 above Dmin, and contains a cyan dye-forming development inhibitor releasing (DIR) coupler represented by DIR1; DIR1=Coup1-Time-Inh1 â€ƒwherein Coup1 is a coupler nucleus that releases -Time-Inh1 and forms a cyan dye upon reaction with oxidized developer, Time is a group that permits -Time-Inh1 to be cleaved from Coup1 and to diffuse within the photographic element during development processing and is thereafter cleaved from Inh1, and Inh1 is an inhibitor group of high strength capable of inhibiting the development of a silver halide emulsion upon release from Time; c) all of the blue light sensitive layers other than the slowest blue light sensitive layer independently contain a yellow dye-forming DIR coupler represented by DIR2: DIR2=Coup2-Inh2 â€ƒwherein Coup2 is a coupler nucleus that releases -Inh2 and forms a yellow dye upon reaction with oxidized developer during development processing, and Inh2 is an inhibitor group capable of inhibiting the development of a silver halide emulsion other than one qualifying as a high strength inhibitor.
