ABSTRACT:
A multi-layered corrosion-resistant label comprising a printed layer of a first corrosion-sensitive material, a transparent second layer of a second material different from the printed layer covering the front surface of the printed layer, and being of a shape similar to that of the first layer in plan view and of a second size greater than the first size, a third layer of a material different from the printed layer covering the back surface of the printed layer and being of a shape similar to that of the first shape and of a size greater than the first size, with the second and third layers enveloping the printed layer and providing a protective border surrounding the printed layer so that the peripheral edge of the printed layer is spaced inwardly from the peripheral edges of the second and third layers. A first adhesive layer bonds the second layer to the front surface of the first layer across its surface, a second adhesive layer bonds the inner surface of the third layer to the back surface across its surface, and one of the first and second adhesive layers extends to the peripheral edges of the second and third layers for bonding the second and third layers to each other to define the protective border. A third, pressure-sensitive adhesive layer on the outer surface of the third layer secures the label to the surface of an object, and a release liner covers the third adhesive layer.
