    Abstract: An optical construction includes a lens film having an outermost structured first major surface and an opposing outermost substantially planar second major surface. The structured first major surface includes a plurality of microlenses. A solvent-deposited optically opaque mask layer is applied over the second major surface of the lens film. The mask layer has an average thickness of less than about 10 microns and defines a plurality of laser-ablated through openings therein. The through openings are aligned to the microlenses in a one-to-one correspondence, such that for a light incident on the structured first major surface along an incident direction forming an incident angle with the second major surface, an optical transmittance of the optical construction as a function of a transmitted angle includes a first transmitted peak having a first peak transmittance T1 ≥ 40%. The first transmitted peak can be within about 10 degrees of the incident angle.

    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.
