Abstract
A media sheet which can be used with a new system and method of the present invention is provided. Specifically, a media sheet can comprise a substrate, a porous dye-receiving layer deposited on the substrate, and a porous ionic layer deposited on the porous dye-receiving layer. Thus, when the ink-jet ink is printed onto the media sheet, ink-jet ink passes substantially through the porous ionic layer and onto the porous dye-receiving layer forming an ink-jet ink-containing media sheet. A fluid sealant composition having an opposite polarity than the ionically-charged surfaces can then be applied. Upon application of the fluid sealant to the ink-jet ink-containing media sheet, an interpolymer complex is formed sealing the ink-jet ink in the media sheet.
