Ink composition that includes from about 0.1 to about 10 wt % of metal oxide pigment particles, having an average particle size in the range of about 3 to about 300 nm, that are dispersed with polyether alkoxysilane dispersants; and from about 0.01 to about 3 wt % of watersoluble amphiphilic polymers or of water-dispersible polymer waxes, based on the total weight of the ink composition. Said ink composition forms, onto printable media, a printed feature that exhibits a metallic appearance. Also described herein are the resulting printed article and the method to produce it.
