ABSTRACT:
A silver halide emulsion is disclosed including a blend of a first image dye-forming coupler which does not intrinsically inhibit development of silver halide, and a second image dye-forming coupler which intrinsically inhibits development of silver halide. The intrinsically development inhibiting couplers are defined empirically versus a standard coupler. For purposes of this invention DIR couplers are not considered intrinsically development inhibiting couplers. Photographic elements and methods for developing images using the coupler blends are also disclosed.
