More Information
Summary:The disclosed light directing article comprises a structured layer, an adhesive sealing layer, and barrier elements. The structured layer comprises multiple microstructured elements that are opposite a major surface. The adhesive sealing layer has a first region and a second region. The second region is in contact with the structured layer. The barrier element are at the first region. The first region with the barrier element and second region have sufficiently different properties to form a low refractive index layer between the adhesive sealing layer and the structured layer. The barrier element comprises a crosslinked polymeric matrix having a modulus of elasticity less than 4.4 GPa.
