ABSTRACT:
A security label with a sheet material having a first major surface. An adhesive layer containing an identifier medium is coated on the first major surface. A barrier medium is selectively applied on an exposed surface of the adhesive layer for at least partially blocking diffusion of the identifier medium from the adhesive layer into a substrate. A release liner may be provided that extends substantially over the exposed surface of the adhesive layer. A method of preparing the security label includes applying a barrier medium in the form of an identifier pattern to a low energy surface material. The low energy surface material is laminated to a security label having an adhesive layer containing an identifier medium. When the low energy surface material is removed from the adhesive layer, the barrier medium substantially transfers to the adhesive layer to block diffusion of the identifier medium into a substrate.
