A retroreflective article including a binder layer and a plurality of retroreflective elements. Each retroreflective element includes a transparent microsphere partially embedded in the binder layer. At least some of the retroreflective elements include a reflective layer that is a locally-laminated reflective layer that is embedded between the transparent microsphere and the binder layer. At least some of the locally-laminated reflective layers may be localized reflective layers.

Retroreflective article comprising locally-laminated reflective layers

A light guide comprising a polymeric layer at least 25 percent transmissive over at least a 30 nm bandwidth in a wavelength range from 180 to 280 nm over a distance of at least 100 micrometers and visible light transparent reflecting layers (UV-C mirror) that are at least 50 percent reflective over at least 30 nm bandwidth in a wavelength range from 180 to 280 nm over an incident light angle of 0 to 90 degrees and that are at least 25 percent transmissive of visible light over at least 30 nm bandwidth in a wavelength range of 400 to 800 nm over an incident light angle of 0 to 90 degrees. The light guide is useful, for example, for antimicrobial surfaces.

Ultraviolet C light guides

An article is provided. The article includes an acrylate layer; a substrate overlaying the acrylate layer; and an adhesive layer between the acrylate layer and the substrate, wherein the adhesive layer includes germanium; wherein a release value between the acrylate layer and the adhesive layer is more than 200 g/inch.

Interfacial adhesion article and method

A transfer article () is provided. The transfer article () includes a release layer (), wherein the release layer () comprises a metal layer or a doped semiconductor layer; a first acrylate layer () overlaying the release layer (); and a function layer () overlaying the first acrylate layer (); wherein a release value between the release layer () and the first acrylate layer () is from 2 to 50 g/inch.
