Abstract
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 backing and the face film. The protective web 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.

Claim 1
Independent Claim
205 words
A method of forming discrete labels on a temporary carrier web having a release surface which comprises: forming discrete label face films releasably adhered to the release surface of the carrier web and comprising at least one layer of radiation-cured polymer by coating discrete areas on the release surface corresponding to labels being formed with at least one layer of radiation-curable liquid and curing the liquid by exposure to polymerizing radiation; applying pressure-sensitive adhesive in liquid form over the discrete label face films substantially in register with the label face films; solidifying the liquid adhesive to form discrete labels, each label having a face film releasably adhered to 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 covering the pressure-sensitive adhesive with a protective backing have a release surface in contact with the adhesive, the adhesion between the adhesive and the release surface of the backing being weaker than the adhesion between the face film and the release surface of the carrier web, whereby the protective backing can be removed from such a label to expose the layer of adhesive while leaving the label releasably adhered to the carrier web.
