Abstract
The invention provides a dye set comprising a magenta dye, a yellow dye, and a cyan dye wherein the normalized spectral transmission density distribution curve of the magenta dye has a density between 0.25 and 0.93 at 520 nm, a density between 0.9 and 1.0 at 540 nm, and a density between 0.9 and 1.0 at 560 nm and the yellow dye has a density between 0.9 and 1.0 at 450 nm and a density between 0.8 and 1.0 at 470 nm. Such a dye set enables an increase in the color gamut obtainable for imaging.
