Abstract
A topcoat layer that has a defined surface structure on an outer surface thereof once the topcoat layer is laminated to a substrate. The surface structure of the topcoat layer provides a matte surface finish to the underlying substrate. Any attempt to alter the substrate or the topcoat layer will result in disruption or destruction of the surface structure of the topcoat layer making such tampering evident. Replication of the surface structure of the topcoat layer by a counterfeiter is also difficult without the appropriate equipment.
