Abstract
The present invention is drawn to systems and coated substrates for ink-jet ink printing. The coated media substrate can comprise a substrate, having coated thereon, a porous coating, wherein the porous coating comprises silica having crown compounds covalently attached thereto. The system utilizes a coated media substrate wherein the coating is functionalized with crown compounds, and further provides an ink-jet ink composition that has an affinity for the crown compounds.
Claims26
A coated media substrate for ink-jet ink printing, comprising:
- (a) a media substrate, having coated thereon,
- (b) a porous coating, said porous coating comprising silica having crown compounds covalently attached thereto through reactive groups.
A system for producing permanent ink-jet ink images, comprising:
- (a) a substrate, having coated thereon a porous coating, said porous coating comprising silica having crown compounds covalently attached thereto through reactive groups;
- and
- (b) an ink-jet ink comprising a composition configured for chemically interacting with the crown compounds upon printing the ink-jet ink onto the porous coating.
