Color photographic negative elements with enhanced printer compatibility |
摘要 |
A silver halide photographic negative has a red sensitive layer containing a coupler which reacts with oxidized color developer to form a cyan dye, a blue sensitive layer containing a coupler which reacts with oxidized color developer to form a yellow dye, and a green sensitive layer containing a coupler which reacts with oxidized color developer to form a magenta dye. The coupler in the green sensitive layer produces a magenta dye which has relatively low density in the 560-590 nm range as compared with magenta dyes produced by pyrazolotriazole type couplers or 1-phenyl-3-acylamino-5-pyrazolone couplers. The element additionally has an inert dye present, preferably positioned below the green sensitive layer containing the foregoing coupler. The inert dye has a peak absorption between 560-590 nm so that the negative has a ratio of density at 580 nm to density at 550 nm, both as measured at neutral midscale exposure, which is greater than exhibited by the element absent the inert dye.
