ABSTRACT:
In accordance with the invention a set of dyes suitable for use in ink-jet inks and method for formulating the same are provided. The yellow ink of the present invention contains a yellow colorant having a CIELAB hue angle, h.degree., less than 90.degree. to provide a true representation of colors, particularly skin tone colors. More specifically, a specific dye set for formulating the yellow, cyan, and magenta inks is disclosed, comprising Yellow 104, Direct Blue 199, and Magenta 377 dyes, respectively. The Yellow 104, the Magenta 377, and the DB 199 dyes provide near photographic images having lightfast characteristics necessary to preserve the trueness of the inkjet images by (1) producing images having less light fade and (2) images that when they do fade, fade in a more uniform manner across the color set.
