Abstract:
A multilayer silver halide color photographic element comprising a support having coated thereon at least two red-sensitive silver halide emulsion layers having different sensitivity to red light, characterized in that the most sensitive of said red-sensitive silver halide emulsion layers comprises a core-shell silver bromoiodide tabular emulsion having a pure bromide core, a total silver iodide content lower than 10% and an aspect ratio higher than 5.0 and a Speed Enhancing (SE) cyan coupler represented by one of the following general formulas: wherein A represents (TIME)nâ€”Sâ€”R1â€”R2, TIME is a timing group releasing Sâ€”R1â€”R2with delay under development conditions; n represents 0 or 1; R1 is a divalent linking group, and R2 represents a water-solubilizing group or â€”NR3â€”R4, wherein R3 and R4, which may be the same or different, each represents a hydrogen atom or an aliphatic group having from 1 to 3 carbon atoms; R5 and R9 represent a non-diffusible ballasting group, R6 represents a group capable of substituting a hydrogen atom of the naphthol ring, m represents 0 to 3, R7 represents hydrogen or a halogen atom, R8 represents an alkyl group, and R10 represents an aryl group.
