ABSTRACT:
Methods of preparing media sheets for inkjet printing applications are provided. In one embodiment, the media sheets can be prepared by dispersing or dissolving inorganic porous particulates and an active ligand-containing organosilane reagent in water; reacting the inorganic porous particulates and the active ligand-containing organosilane reagent to form media coating composition; and applying the media coating composition to a media substrate. In another embodiment, the media sheets can be prepared by coating a media substrate with inorganic porous particulates; dispersing or dissolving an active ligand-containing organosilane reagent in water to form a liquid coating composition; and applying the liquid coating composition to the inorganic porous particulates that has previously been coated on the substrate.
