Abstract

Methods of making articles using structured tapes are disclosed. The structured tapes may include a structured template layer having a structured surface and an opposed second surface and an uncured backfill layer, the uncured backfill layer has a lower refractive index than the structured template layer, and the uncured backfill layer has a structured surface conforming to the structured surface of the structured template layer and an opposed second surface. The structured tapes may include a structured template layer having a structured surface and an opposed second surface and an uncured backfill layer, the uncured backfill layer has a higher refractive index than the structured template layer, and the uncured backfill layer has a structured surface conforming to the structured surface of the structured template layer and an opposed second surface. The structure tapes may be laminated via the uncured backfill layer to a receptor substrate to form an article.
