Abstract:
The present invention is generally directed to treated silica particulates for use in ink-jet media coatings, comprising silica particulates being surface-activated by a surface activating agent; the surface active agent including an aluminum chloride hydrate, and where the silica particulates are also reagent-modified by an organosilane reagent; the organosilane reagent including an amine-containing silane.
