Articles and methods for forming optically variable thin film flakes and replicated coatings having preselected optical properties. The articles generally comprise a flexible web of material and an optically variable thin film coating formed on one surface of the web. The optically variable coating is separated from the web to form optically variable thin film flakes. The flakes are disposed in ink and paint vehicles to provide optically variable inks, paints and the like. |
