Abstract
In accordance with embodiments of the present invention, an ink-jet ink can comprise a metallized phthalocyanine dye and a liquid vehicle carrying the dye. The liquid vehicle can include an amine additive present in the ink-jet ink at an effective concentration to cause improvement of ozone fastness. The improvement can be determined by comparing the ozone fastness of the ink-jet ink with a control ink-jet ink that does not include the amine additive.
