Abstract
A high security label is disclosed which includes a multiple layer security label with a base layer with a permanent adhesive coated on its lower surface. Indicia or markings are applied to the bottom surface of the top layer. The top layer is laminated to the upper surface of the base layer by a permanent patterned adhesive. The patterned adhesive is formed so as to leave a portion of the upper surface of the base layer and the bottom surface of the top layer free from adhesive. The markings are applied to the bottom surface of the top layer in at least the adhesive free areas.
