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 an alumina particulate having an active ligand covalently attached thereto or adsorbed thereon. Preferably, the alumina particulate is an aluminum oxide having surface hydroxyls.
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 an aluminum oxide particulate having surface hydroxyls being modified by an attached organic active ligand.
A system for producing permanent ink-jet ink images, comprising:
- (a) a substrate, having coated thereon a porous coating, said porous coating comprising active ligand-modified alumina particulates;
- and
- (b) an ink-jet ink comprising a composition configured for interacting with the active ligand portion of the active ligand-modified alumina particulates upon printing the ink-jet ink onto the porous coating.
