Abstract

A silver halide light sensitive motion picture photographic print element is disclosed comprising a support bearing on one side thereof: a primarily yellow dye image-forming unit comprising at least one blue-sensitive silver halide emulsion layer having associated therewith primary yellow dye-forming coupler and secondary cyan and magenta dye-forming couplers; a primarily cyan dye image-forming unit comprising at least one red-sensitive silver halide emulsion layer having associated therewith an effectively primary amount of cyan dye-forming coupler and effectively secondary amounts of magenta and yellow dye-forming couplers; and a primarily magenta dye image-forming unit comprising at least one green-sensitive silver halide emulsion layer having associated therewith an effectively primary amount of magenta dye-forming coupler and effectively secondary amounts of cyan and yellow dye-forming couplers; wherein the primary and secondary dye-forming couplers in each of the dye image-forming units are present in amounts effective to obtain a ratio of Equivalent Neutral Density for the dyes formed from each of the primary dye-forming couplers to each of the secondary dye-forming couplers in each dye-image forming unit of from 20:1 to 3:2 in the print film upon exposure and processing in the standard ECP-2B motion picture color print process, such ratios measured at an exposure resulting in an Equivalent Neutral Density of 1.0 for the primary image dye color of the respective unit. Color print film silver halide photographic elements with mixed color dye image-forming couplers in each of the dye image-forming units thereof enable the production of projected images having desired black densities and colored images having desired degrees of color saturation.
