Abstract: The present invention is drawn to a composition for cast-coating on ink-jet media. The composition includes a liquid vehicle, silica particulates, and an internal release agent. The composition is substantially free of polymeric binder and can improve the glossiness of a porous particulate-coated ink-receiving media by at least 2 gloss units at 20 degrees. The silica particulates can be suspended in the liquid vehicle at about 1-35 wt %, and can have a particle size of less than about 150 nm. The internal release agent can be present at about 0.5-10 wt %.

Abstract: The present invention is drawn to a media sheet, comprising a substrate and a porous ink-receiving layer deposited on the substrate. The porous ink-receiving layer can comprise inorganic metal or semi-metal oxide particulates bound by a polymeric binder, and the porous ink-receiving layer can further include an effective amount of a sulfur-containing compound that interacts with ozone upon exposure thereto.

Abstract: Methods of polymerizing polyethylene-based polymers on a support, and supports coated with polyethylene-based polymers. The coated supports may be used to improve the ink fixation properties of an ink-jet printing medium. The coated supports may also be useful for highly tailored chromatographic separations.

Abstract: An inkjet receiver layer is constructed of an alumina-containing layer also containing a binder with an essentially binder-free, colloidal, cationic silica top-coat. The colloidal cationic silica topcoat provides improved image quality (color gamut and gloss) and increased resistance to scratching, while maintaining a high absorption of ink.

Abstract: A method of making an inklet recording sheet having pigment-binder gradient in the ink-receiving layer is provided. The method includes providing a support and forming an inkjet receiver layer over the support. The receiver layer has a lower-most portion over the support and an upper-most layer. The inkjet receiver layer is formed with a gradient in ration of binder to pigment ranging from more binder and less pigment in the lower-most portion and less binder and more pigment in the upper-most portion.

Abstract: Medium for chromatographic separations. The medium includes a support with a surface on which interwoven polymers are coated to form a polymer surface. The polymers are covalently linked to the support surface. The polymers are each formed from one or more monomer types and at least one monomer type has an amine functional group. The medium also includes an active molecule immobilized on the polymer surface that is selected to separate reagent materials by chemical structure.

Abstract: An ink jet inkjet receiver layer on a substrate consists of at least two layers of similar composition of binder and pigment, except that the layer next to the substrate has a smaller pigment/binder ratio versus the layer laid on top of it. Multiple layers making up the gradient are included.

Abstract: The present invention is drawn to the thermal transfer overcoating of images printed on porous media, and methods of overcoating images printed on porous media. Upon use of the systems and methods of the present invention, a thermally coated print is generated that can comprise a porous media substrate having printed thereon a digitally produced image. The digitally produced image and the porous media substrate is thermally coated by an adhesive protective layer, wherein the adhesive protective layer has a tangent d that is greater than 1 and melt viscosity less than 1×105 Pa.·sec. as applied above its phase transition temperature. Thus, the voids in the porous media substrate can be substantially filled, and further, substantially no tags remain on the print.

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.

Abstract: An ink set for ink-jet printing, having at least one ink of the ink set comprising a light dye load and a dark dye load with both the light dye load and the dark dye load being one color. The one color is selected from magenta, cyan, yellow and black; and the light dye load being at least one of air fade resistant, light fade resistant and humid color migration resistant. The invention also relates to a method of inkjet printing with such a method.
