Abstract:
An optical article has a substrate including a reflective polarizing element preferentially reflecting light having a first polarization state and preferentially transmitting light having a second polarization state and a beaded layer disposed on the substrate. The beaded layer includes transparent binder and a plurality of transparent beads dispersed therein. A normal angle gain of the optical article with the beaded layer is increased when compared to a normal angle gain of the same optical article but without the beaded layer.
