Abstract: A method for providing a waterborne, inorganic barrier coating to a polyolefin substrate is described. The method involves applying a primer composition containing a vinyl polymer, wherein at least 75 % of the polymer repeat units contain side groups having hydroxyl moieties, to the substrate. This primer coating facilitates the application and binding of the subsequently applied barrier coating composition to the substrate.

Abstract: A method and novel barrier coating solutions are provided for imparting improved vapor, gas or aroma permeability characteristics to a coated polymeric substrate. The method and solutions employ a lithium-potassium copolysilicate of the formula (Li2O)x(K2O)1-x(SiO2)y. For the method, y is between 1 and 10, if x is less than 1; or y is greater than 4.6, if x is 1. For the novel coating solutions, y is greater than 4.6 if x is less than 1; or x is greater than 0.5 if y is between 1 and 10.

Abstract: This invention provides novel moisture barrier protective layers for polarizers, as well as laminates comprising those layers useful for display device applications. The protective layer comprises polymers of a cyclic olefin, and the polarizing layer comprises a liquid crystalline polyester and a dichroic absorber. An illustrative laminate comprises a polarizing layer, and a protective layer, bonded by means of an intermediary adhesive layer. The protective layer offers excellent moisture protection to the laminate. The invention further provides a process to prepare such laminates.
