Abstract
The present invention is directed to ink-jet inks, ink sets, and methods of printing images. The ink-jet ink can comprise a cyan phthalocyanine dye, a divalent salt, an anti-flocculent aromatic polyamine, and a liquid vehicle. The cyan phthalocyanine dye can be susceptible to destabilization by the presence of the salt, and the anti-flocculent aromatic polyamine can be present at a concentration that stabilizes the cyan phthalocyanine dye in the presence of the divalent salt.
