Abstract
An optical security label for security and anti-counterfeit applications comprises a first layer having an optically variable portion (diffractive, holographic or interference film) generating an optically variable effect secured to a support layer by a weak adhesive layer such that the first layer can be scratched off the third support layer to reveal underlying data and the label is affixed to a substrate by a pressure sensitive adhesive. The label or substrate carry the data to be protected such a printed or personalized paper or plastic substrate. In one aspect the scratch off region is patterned and also the data can comprise a pattern of alternate scratch off and permanent areas. In one aspect the label is a thin frangible structure delivered to the substrate with a weakly bound top carrier. In another aspect the optical variable device includes a covert image authenticated by a decoder carried on the top of the removable carrier. In one aspect the pressure sensitive adhesive is a curable adhesive to provide a permanent bond.
