Abstract: A printable overlaminate for attachment to a substrate permits application of decorative and/or informative printing on materials that normally are not receptive to ordinary inks. The overlaminate has a release liner releasably attached to a protective layer. On the protective layer is an ink acceptable adhesive, the exposed surface of which receives ordinary ink. After printing the ink acceptable layer is transferred to a substrate through the use of heat and pressure. Then the release liner is removed, leaving the ink visible through the protective layer.

Abstract: A protective lamination film for an identification card or other document, of the kind comprising a tough, abrasion-resistant transparent polyester film coated with polyethylene or other adhesive activatable by heat and pressure, has a multiplicity of slits cut into the film in a pattern that allows the film to hold together in normal use but causes the film to tear if any post-lamination alteration is attempted; the film may be employed as an outer cover for the document, or it may comprise separate film interposed between the document and a continuous film providing an external cover.
