Abstract
A surface of a plastic article is metallized without substantial pinholes, holidays and the like by initially coating the surface with an aqueous colloidal dispersion of an organic polymer, particularly a barrier polymer such as polyvinylidene chloride, treating the organic polymer coating to make it metallizable and subsequently overcoating the treated organic polymer coating with a metal to form a thin metal layer adherent to the organic polymer layer. The resulting metallized plastic article which can optionally be treated with an additional amount of an aqueous colloidal dispersion of an organic polymer or metal is essentially impermeable to atmospheric gases and other vapors.
