Abstract
An article for applying a color shifting optically variable coating on a substrate formed from a polymeric web, a release coating on the web and an optically variable coating wherein the optically variable coating consists of a semi-opaque metal layer adjacent to the release layer, a transparent dielectric layer on the semi-opaque metal layer and a reflective metal layer on the dielectric layer. The article can be bonded to a substrate by means of hot stamping with the hot stamp adhesive layer being applied to the article or applied to the substrate.
