ABSTRACT OF THE INVENTION 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 laminate comprising a trans- parent or translucent outer sheet having an information con- taining pattern printed on its inner surface, said printed inner surface having a coating of pressure sensitive ad- hesive film coated thereon. The printed pattern has a lesser affinity for the outer sheet than the printed pattern has for the adhesive. The affinity of the adhesive for the surface to which the laminated label is adhered and to the printed pattern is greater than the affinity of the printed pattern for the the outer sheet. In a preferred embodiment the free side of the adhesive film of the label is covered by a release sheet. Once applied to a substrate, if removal of the label is attempted, the label delaminates in a manner such that the outer sheet separates leaving at least a portion of adhesive layer, having at least a portion of the printed pattern adhering thereto, adhered to the substrate.
