Abstract: The present invention is drawn to compositions and coated substrates wherein a back coating layer can be implemented for use to mitigate ink transfer, surface damage, smudging, and sticking between stacked sheets in output trays of ink-jet ink printers. Specifically, a coated media sheet can comprise a printing surface including an ink-receiving coating formulated to accept an ink-jet ink composition, and an opposing back surface comprising a back coating. The back coating can include an admixture of 0.5 wt % to 75 wt % of a polymeric binder, 5 wt % to 95 wt % of filler particulates having an average particle size from about 0.01 ?m to about 15 ?m, and 3 wt % to 90 wt % of spacer particulates having an average particle size from about 6 ?m to about 500 ?m. In one embodiment, the spacer particulates are larger than the filler particulates.

Abstract: An ink-jet media sheet imparting superior image quality and permanence is disclosed. Such a sheet may comprise a substrate consecutively coated with a porous ink-absorbing layer and a porous ink-receiving layer, where the specific surface area of the particulates of the ink-absorbing layer is less than that of the ink-receiving layer, e.g., the particulates are generally smaller in the ink-receiving layer. The porous coating layers can comprise semi-metal or metal oxide particulates and may further include other surface treatment or reactive groups having functional moieties to promote fixing and localizing printed colorants. Images printed on these media sheets exhibit good fastness to water, ozone, and humidity as well as improved color gamut and black intensity.

Abstract: The present invention is drawn to compositions and coated substrates wherein a back coating layer can be implemented for use to mitigate ink transfer, surface damage, smudging, and sticking between stacked sheets in, output trays of ink-jet ink printers. Specifically, a coated media sheet can comprise a printing surface including an ink-receiving coating formulated to accept an ink-jet ink composition, and an opposing back surface comprising a back coating. The back coating can include an admixture of 0.5 wt % to 75 wt % of a polymeric binder, 5 wt % to 95 wt % of filler particulates having an average particle size from about 0.01 ?m to about 15 ?m, and 3 wt % to 90 wt % of spacer particulates having an average particle size from about 6 ?m to about 500 ?m.

Abstract: A print medium having improved image quality and permanence. The print medium comprises a coated paperbase and an ink-receiving layer. The ink-receiving layer is present on the coated paperbase at less than approximately 10 grams per square meter. A method of forming the print medium is also disclosed. In addition, a method of printing an image having improved image quality and permanence is disclosed.
