Abstract: A barrier film including a substrate; a base polymer layer adjacent to the substrate; an oxide layer adjacent to the base polymer layer; a adhesion-modifying layer adjacent to the oxide layer; and a top coat polymer layer adjacent to the adhesion-modifying layer. An optional inorganic layer can be applied over the top coat polymer layer. The inclusion of a adhesion-modifying layer provides for enhanced resistance to moisture and improved peel strength adhesion of the top coat polymer layer to the underlying barrier stack layers.

Abstract: A barrier film including a substrate, a base (co)polymer layer applied on a major surface of the substrate, an oxide layer applied on the base (co)polymer layer, and a protective (co)polymer layer applied on the oxide layer. The protective (co)polymer layer is formed as the reaction product of a first (meth)acryloyl compound and a (meth)acryl-silane compound derived from a Michael reaction between a second (meth)acryloyl compound and an aminosilane. The first and second (meth)acryloyl compounds may be the same. In some embodiments, a multiplicity of alternating layers of the oxide layer and the protective (co)polymer layer may be used. An oxide layer can be applied over the top protective (co)polymer layer. The barrier films provide, in some embodiments, enhanced resistance to moisture and improved peel strength adhesion of the protective (co)polymer layer(s) to the underlying layers. A process of making, and methods of using the barrier film are also described.

Abstract: An optical system includes a lens layer including a plurality of microlenses arranged along orthogonal first and second directions, and at least one optically opaque mask layer spaced apart from the lens layer and defining a plurality of through openings therein arranged along the first and second directions. There is a one-to-one correspondence between the microlenses and the openings, such that for each microlens, the microlens and corresponding openings are substantially centered on a straight line making a same oblique angle with the lens layer. An optical layer can include the lens layer and the optically opaque mask layer embedded in the optical layer.
