[ What is claimed is:] [1.] A method of depositing a multilayer barrier coating on a plastic substrate in a previously evacuated chamber comprising:(a) selecting a curable component comprising: i) polyfunctional acrylates, or ii) mixtures of monoacrylates and polyfunctional acrylates;(b) flash vapor

[ What is claimed is:] [1.] A method of depositing a multilayer barrier coating on a plastic substrate in a previously evacuated chamber comprising:(a) selecting a curable component comprising: i) polyfunctional acrylates, or ii) mixtures of monoacrylates and polyfunctional acrylates;(b) flash vaporizing said component into said chamber;(c) condensing a first layer of a film of vaporized component onto the outer surface of said container;(d) curing said film;(e) vaporizing an organotin component, an organosilicon component and admixing the volatilized components with an oxidizer component and optionally an inert gas component to form a gas stream exterior to the chamber;(f) establishing a glow discharge plasma in the chamber from one or more of the gas stream components;(g) controllably flowing the gas stream into the plasma while confining at least a portion of the plasma therein; and(h) depositing a layer of a mixture of tin oxide and silicon oxide adjacent said first layer.
