Abstract: This invention is directed to substrates and articles utilizing these substrates that provide improved performance of printable electronics on polymer substrates. In particular, the improved substrates relate to polymer films and electrical conductors printed on them. Application of a thin polymeric coating to the polymer film provides the improved performance of the printed conductors.

Abstract: A security film adapted to display a message indicative of tampering is disclosed. A light transmitting sheet has a first layer on one surface, a release layer on a portion of the opposite surface, and a second layer covering the release layer and another portion of the opposite surface. The first layer is a metal and the second layer is a metal or a non-metal. An adhesive layer on the second surface adheres the film to a substrate. Removal of the sheet from the substrate causes the sheet to separate from the second layer under the release layer making a release layer pattern visible on both the sheet and substrate as reverse images. A method disclosed includes metalizing a light transmitting sheet with a metal layer on one side and a release layer and a metal or a non-metal layer on the opposite side.
