Abstract
A multilayer structure has barrier properties for gases and vapors, for example oxygen and water vapor; the structure comprises: an organic substrate layer, and a multilayer permeation barrier thereon; the barrier comprises: a) a first inorganic coating contacting a surface of the substrate layer, and b) a first organic coating contacting a surface of the inorganic coating; the structure may be employed in a variety of articles where barrier properties are important especially in electronic articles such as organic light emitting diode devices where superior barrier characteristics over the life of the device are required.
