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.

Dependent claims

A method of making an article comprising:

providing a structured tape comprising:
a carrier;
a structured template layer having a structured surface and an opposed second surface, wherein the opposed second surface of the structured template layer is in contact with the carrier;
an uncured backfill layer, wherein 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;
laminating the opposed second surface of the uncured backfill layer to a receptor substrate, without an adhesion promotion layer and wherein the uncured backfill layer is tacky, to form an article.
