    Abstract: A printed article with optically variable properties that includes a printable media on which a printed feature has been formed with an ink composition. Said ink composition contains metal oxide particles that have an average particle size in the range of about 3 to about 180 nm and that have a refractive index superior or equal to 1.2. The printable media contains a bottom supporting substrate, an ink-absorbing layer and a metallized top layer with pore diameters that are smaller than the size of the metal oxide particles, and the ink composition forms, onto the printable media, a printed feature that exhibits optically variable properties.

    Abstract: A method of security printing can comprise the steps of printing a transparent ink onto a portion of a coated substrate resulting in printed region and an unprinted region, where the transparent ink is devoid of dyes, pigments, ceramics, metallics, and fluorescents; illuminating both the printed region and the unprinted region of the substrate, where the printed region scatters more light than the unprinted region creating a contrast; and detecting the contrast with a sensor that is sensitive to detecting light scattering differences between the printed region and the unprinted region.

    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.
