<p>In accordance with the invention inks suitable for use in ink-jet printers and method for formulating the same are provided. The present dye set exhibits excellent color quality and lightfastness across a range of media. Furthermore, the dye set preserves its performance over a wide pH range, particularly low pH. This functionality across a wide pH range, enables the use of pH- sensitive bleed control mechanisms. More specifically, a specific dye set for formulating the yellow, magenta, and cyan inks is disclosed, comprising Direct Yellow 132 and Acid Yellow 23; Magenta 377 and Acid Red 52; and Direct Blue 199 and Acid Blue 9; respectively.</p> |
