OPTICAL FILM, METHOD FOR PRODUCING OPTICAL FILM, AND SURFACE LIGHT-EMITTING BODY

摘要

This optical film includes a substrate and a plurality of convex microlenses arrayed on the substrate. The microlenses have an α-region and a β-region. The β-region occupies the outer portion of the convex shape of the microlenses, and is positioned in a manner so as to cover the α-region. In an adhesion test conforming to ISO 2409 for measuring the adhesiveness of the substrate and the optical film, the test result is class 0 or class 1.

主权项

1. An optical film comprising a base material and a plurality of convex microlenses arranged on the base material, the microlens having an α-region and a β-region, the β-region occupying the outer portion of the convex shape of the microlens and being positioned so as to cover the α-region, wherein
a resin composition constituting the α-region has a test result of class 0 or class 1 in an adhesion test in conformity with ISO 2409 for measuring adhesiveness between the base material and the resin composition constituting the α-region.
