Abstract
Silver halide photographic elements that are color intermediate motion picture films have at least one green sensitive silver halide emulsion that includes a green sensitizing dye that is a cyanine dye having two oxazole groups in the molecule, and another green sensitizing dye having either two imidazole groups in the molecule or one oxazole group and one thiazole group in the molecule. The molar ratio of the first green sensitizing dye to the second green sensitizing dye is from about 4:1 to about 0.3:1. The magenta dye image forming unit has at least one green sensitive silver halide emulsion layer that comprises predominantly cubic silver iodobromide grains having at least 90 mol % bromide and at least 1 mol % iodide, which grains have an average equivalent spherical diameter (ESD) of less than 0.25 μm.
Claims23
A silver halide photographic element that is a color intermediate motion picture film designed for exposure by laser radiation, the element having an ISO film speed of less than 1, and comprising a support having thereon:
- a cyan dye image forming unit comprising at least one red sensitive silver halide emulsion,
- a magenta dye image forming unit comprising at least one green sensitive silver halide emulsion, and
- a yellow dye image forming unit comprising at least one blue sensitive silver halide emulsion,
- wherein the magenta dye image forming unit has at least one green sensitive silver halide emulsion layer that comprises predominantly cubic silver iodobromide grains having at least 90 mol % bromide, which grains have an average equivalent spherical diameter (ESD) of less than 0.25 μm,
- the green sensitive silver halide emulsion layer further comprising a first green sensitizing dye that is a cyanine dye having two oxazole groups in the molecule, and a second green sensitizing dye having either two imidazole groups in the molecule or one oxazole group and one thiazole group in the molecule, and the molar ratio of the first green sensitizing dye to the second green sensitizing dye is from about 4:1 to about 0.3:1.
