Abstract
A label construction comprises a temporary carrier web having a release surface and a label releasably adhered to the release surface. The label comprises a radiation cured face film in contact with the release surface of the carrier web and a layer of pressure sensitive adhesive on the side of the label opposite the carrier web, and may comprise indicia between the face film and the layer of adhesive. A protective backing covers the adhesive and has a second release surface in contact with the adhesive. Adhesion between the release surface of the protective backing and the layer of adhesive is weaker than adhesion between the release surface of the temporary carrier web and the face film. The protective backing can be removed from the label to expose the adhesive while leaving the label releasably adhered to the carrier web. The exposed adhesive is applied to a substrate and the temporary carrier web is removed, leaving the label adhered to the substrate.
