Patent ID: 6905729

Claim:
A method of preparing a media sheet for ink-jet printing applications, comprising: (a) dispersing or dissolving inorganic porous particulates and an active ligand-containing organosilane reagent in water, said 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, with the proviso that both R1 and R2 are present; (b) reacting the inorganic porous particulates and the active ligand-containing organosilane reagent to form media coating composition; and (c) applying the media coating composition to a media substrate.
