LASER MARKING PROCESS AND ARTICLES |
摘要 |
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. Multilayered articles having multi-layer laser markings are also disclosed. |
