Abstract
In accordance with embodiments of the present invention, an ink-jet ink can comprise a dye and a liquid vehicle carrying the dye. The liquid vehicle can include a sulfonated aromatic compound present in the ink-jet ink at an effective concentration to cause improvement of ozone fastness of said ink-jet ink.
Claims46
An ink-jet ink composition, comprising:
- a dye;
- and
- a liquid vehicle carrying the dye, said liquid vehicle including a sulfonated aromatic compound present in the ink-jet ink at an effective concentration to cause improvement of ozone fastness of said ink-jet ink,
- wherein the improvement is determined by comparing the ozone fastness of the ink-jet ink with a control ink-jet ink that does not include the sulfonated aromatic compound.
A printing system for creating images with improved ozone fastness, comprising:
- a) a printing medium including an ink-receiving layer coated thereon, said ink-receiving layer including semi-metal oxide or metal oxide particulates;
- and
- b) an ink-jet ink configured for printing on printing medium, said ink-jet ink, comprising:
- i) a dye;
- and
- ii) a liquid vehicle carrying the dye, said liquid vehicle including a sulfonated aromatic compound being present in the ink-jet ink at an effective concentration to cause improvement of ozone fastness, wherein the dye and the sulfonated aromatic compound have an association on the media, and wherein the improvement is determined by comparing the ozone fastness of the ink-jet ink with a control ink-jet ink that does not include the sulfonated aromatic compound.
A method for printing images with improved ozone fastness, comprising jetting an ink-jet ink onto a printing medium, said printing medium including an ink-receiving layer coated thereon, said ink-receiving layer comprising semi-metal oxide or metal oxide particulates, said ink-jet ink comprising a dye, and a liquid vehicle carrying the dye, said liquid vehicle including a sulfonated aromatic compound being present in the ink-jet ink at an effective concentration to cause improvement of ozone fastness, wherein the improvement is determined by comparing the ozone fastness of the ink-jet ink with a control ink-jet ink that does not include the sulfonated aromatic compound.
