A thermoplastic resin, a leafing grade aluminum paste, and a solvent are mixed to form a metallic printing ink which is useful for metallizing a wide range of paper stocks by selected conventional printing processes, such as rotogravure printing. The metallic ink can be applied at four pounds per ream (6.5 g/m2) of dry coating to form a satisfactory moisture barrier, but the ink is similar to paint in that a glossy aluminum finish is produced by leafing of the aluminum particles when the coated paper is heated, as by passing the paper over a heated roll.
