OPTICAL MEMBRANE FLAKE, REPLICATED OPTICAL COATING, COATING AND INK MIXED WITH SAID FLAKE AND METHOD

摘要

Articles and methods for forming optically variable thin film flakes and replicated coatings having preselected optical properties. The articles are formed by coating a flexible web of material (20l) with an optically variable thin film coating (202) on one surface of the web. The optically variable coating is then separated (203) 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.
