    Abstract: The polymerization and copolymerization of photographically useful vinyl monomers can be effected by dissolving such monomers in an isotropic oil-in-water microemulsion or in an isotropic water-in-oil microemulsion, each comprising monomers or comonomers, surfactants and/or cosurfactants, water, and optionally electrolytes. The microemulsion may be characterized as transparent or nearly transparent to the eye at 1% (w/w) or greater monomer, ultrafine in particle (droplet) size (typically in the range of 30 to 900 .ANG. in diameter), and spontaneously formed upon combining all the components with moderate stirring. The polymerization process is subsequently initiated with free radical initiators or with ultraviolet light. The components are chosen so that photographically useful polymers or photographically useful latexes are obtained, and said polymers or latexes may be coated in a photographic element.

    Abstract: The present invention is drawn to a method of treating silica in an aqueous environment. The method can comprise steps of dispersing silica particulates in an aqueous environment to form an aqueous dispersion; reversing the net charge of a surface of the silica particulates from negative to positive using a surface activating agent, thereby forming surface-activated silica particulates dispersed in the water; and contacting the surface-activated silica particulates with organosilane reagents to form reagent-modified and surface-activated silica particulates.

    Abstract: The present invention is drawn to a media sheet for ink-jet printing and can comprise a media substrate and a coating composition applied to the media substrate to form an ink-receiving layer. The ink-receiving layer can include semi-metal oxide or metal oxide particulates, at least 5 wt % of a water soluble coating formulation additive, and a binder. The media sheet can also have a wash conductivity less than about 80 microsiemens/cm, said wash conductivity determined by measuring the conductivity of a 50 mL bath of deionized water after placing a 100 cm2 sample of the media sheet in the deionized water for 45 seconds at room temperature under agitation.
