Abstract: Optical constructions are disclosed. A disclosed optical construction includes a reflective polarizer layer, and an optical film that is disposed on the reflective polarizer layer. The optical film has an optical haze that is not less than about 50%. Substantial portions of each two neighboring major surfaces in the optical construction are in physical contact with each other. The optical construction has an axial luminance gain that is not less than about 1.2.

Abstract: A note sheet comprising: (1) a substrate having a first main face and a second main face; (2) a writing receptive layer on the first main face of the substrate, the writing receptive layer having an exposed face or writing surface having a fine relief structure; and (3) at least one segment of repositionable pressure-sensitive adhesive layer on at least a portion of the second main face; wherein the substrate and writing receptive layer having a visible transmittance of at least about 80% and a haze of not more than about 60%. Also a method for making such sheets.
