Abstract
This invention relates to switch-proof labels useful for marking objects in a manner such that, if one were to attempt to transfer the label to another object, the label would be destroyed or defaced to such an extent that its transference would be noticeable. The label comprises a laminate comprising a transparent or translucent outer sheet having an information containing pattern printed on its inner surface, said printed inner surface having a coating of pressure sensitive adhesive film coated thereon.
