Abstract
The present invention is drawn to dye sets for formulating ink-jet inks, including ink sets having six ink-jet inks. In one embodiment, the dye set can comprise a yellow dye for formulating a yellow ink, a pair of magenta dyes for formulating a magenta ink and a pale magenta ink, a pair of cyan dyes for formulating a cyan ink and a pale cyan ink, and a black dye for formulating a black ink-jet ink. The pair of magenta dyes can be a transition metal-containing azo dye and a non-metallized dye. The pair of cyan dyes can be a first copper phthalocyanine dye and a second copper phthalocyanine dye that is different than the first copper phthalocyanine dye.
