Abstract

See full text

Transfer tapes and methods of making transfer tapes are described. In one aspect, the transfer tape comprises a template layer having a structured surface; a backfill layer disposed on at least a portion of the template layer, the backfill layer having a microstructured surface opposite the structured surface; and a layer disposed adjacent the microstructured surface, wherein the layer disposed adjacent the microstructured surface has a refractive index that differs from the backfill layer. The microstructured surface together with the adjacent layer functions as a diffusive layer, or in other words a diffusive interface. Also described are microoptical glazing and methods of making microoptical glazing as well as insulated glazing units and methods of making insulated glazing units.
