    摘要: 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.
