Abstract:
1. A method of preparing a media sheet for ink-jet printing applications, comprising: (a) applying inorganic porous particulates to a media substrate; (b) dispersing or dissolving an active ligand-containing organosilane reagent in water to form a liquid coating composition, wherein the active ligand-containing organosilane reagent is stable in water, and wherein the active ligand-containing organosilane reagent comprises the structure: where x is from 0 to 20-y, y is from 0 to 20-x, and x+y is from 1 to about 20; R1 is lower alkyl, lower alkenyl, acrylate, or methacrylate; and R2 is aminoalkyl, aminoalkyl salts, epoxy, epoxyalkyl, carboxyalkyl, or alkylsulfonate; and (c) reacting the liquid coating composition to the inorganic porous particulates that have previously been coated on the substrate.
