  • Publication number: 20130337213
    Abstract: A process to mark a multilayered article having a release layer and an adhesive layer, using a laser to produce markings within more than one layer of the article. The process includes providing a multilayered article including a laser-markable release liner having a release layer, and a laser-markable adhesive film; and marking the laser-markable release liner and the laser-markable adhesive film by directing laser radiation from at least a first source of laser radiation into the multilayered article through at least the first release layer to induce an interaction between a first light-sensitive pigment and a first organic polymer in the laser-markable release liner, and a second light-sensitive pigment and a second organic polymer in the laser-markable adhesive film, to form at least one visually perceptible marking in each of the laser-markable release liner and the laser-markable adhesive film. The release layer is substantially transparent to the laser radiation.

  • Publication number: 20120141752
    Abstract: A process to mark a multilayered article with a laser (20). The multilayered article (10) includes a laser-markable layer (14) having at least one organic polymer and at least one light-sensitive pigment therein, and including at least one release agent associated with the laser-markable layer. Laser-marking of the laser-markable layer is accomplished by directing laser radiation (22) into the multilayered article through the release agent (12) to induce an interaction between the light-sensitive pigment and the organic polymer. As a result of the interaction, a visually perceptible marking (16) is formed in the article. The laser-marked article includes a laser-markable layer and a first release agent associated with a surface of the laser-markable layer. The marking(s) in the laser-markable layer is visible through the layer of release agent, and the marking is a result of the laser-induced interaction between the light-sensitive pigment and the organic polymer.
