ABSTRACT:
A set of dyes is provided for use in vehicles employing about 5 to 11% of glycols and/or glycol ethers and the balance water. The dye-set comprises about 2 to 3% of hydrolyzed-Reactive Red 180, about 0.3 to 1% Acid Red 52, with the ratio of hydrolyzed-RR180:AR52 ranging from about 2:1 to 5:1, about 1.75 to 2.75% of Acid Yellow 23, and about 1.75 to 2.5% of Acid Blue 9. The particular dye-set provides bright, saturated colors for ink-jet application for not only special coated paper, but also "plain" office papers and transparencies.
