ABSTRACT:
A motion picture sound recording chromogenic photographic film element for forming non-neutral images is disclosed comprising a film support bearing at least one silver halide emulsion layer comprising at least one dye-forming coupler which forms a dye which absorbs primarily in the green or red light region of the electromagnetic spectrum upon processing with color negative developer, wherein the element does not comprise a neutral-balanced combination of cyan, magenta, and yellow dye-forming couplers. A method for forming a soundtrack image in a motion picture print film is also disclosed, comprising recording a soundtrack negative in a chromogenic soundtrack recording film as described above by exposing said film and processing said exposed film with a color developer process to form a dye soundtrack negative, and printing a soundtrack onto a negative-working motion picture print film by exposing the motion picture print film through the dye soundtrack negative and processing the exposed print film to form a positive soundtrack. In accordance with preferred embodiments of the invention, the light-sensitive emulsion layer of the sound recording film comprises green or red light-sensitive silver halide emulsion grains and a cyan or magenta dye-forming coupler in the substantial absence of yellow dye-forming coupler. In accordance with most preferred embodiments, the light-sensitive emulsion layer of the sound recording film comprises green and red light-sensitive silver halide emulsion grains and cyan and magenta dye-forming couplers in the substantial absence of yellow dye-forming coupler.
