Articles including a multilayer optical film and fluoropolymer layers, transfer articles, and methods of making same

Abstract

Articles are provided including a first fluoropolymer substrate having a tetrafluoroethylene (TFE) content of >10 to <55 mole %; a multilayer optical film disposed on the first substrate; and a second fluoropolymer substrate having a TFE content of >55 mole % disposed on the first fluoropolymer substrate opposite the multilayer optical film. The multilayer optical film is composed of alternating first and second layers of high refractive index material and low refractive index material. The multilayer optical film transmits incident light in a wavelength range from at least 400 nanometers to 700 nanometers. Often, the multilayer optical films reflects or absorbs certain wavelength bands within a wavelength range of 190 to 320 nanometers. Transfer articles are also provided including a release layer including a metal layer or a doped semiconductor layer; an acrylate layer disposed on a major surface of the release layer; and a multilayer optical film disposed on a major surface of the acrylate layer opposite the release layer. The disclosure further provides methods of making articles and transfer articles.
