    • 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.
    • 标记具有剥离层和粘合剂层的多层制品的方法,使用激光在制品的多于一层内产生标记。 该方法包括提供包括具有剥离层的可激光标记的剥离衬垫和可激光标记的粘合膜的多层制品; 以及通过将来自至少第一激光辐射源的激光辐射通过至少第一释放层引导到多层制品中来标记可激光标记的释放衬垫和可激光标记的粘合剂膜,以引起第一感光颜料 和可激光剥离衬垫中的第一有机聚合物和可激光标记粘合剂膜中的第二感光颜料和第二有机聚合物,以在每个可激光标记的剥离衬垫中形成至少一个视觉上可察觉的标记 和可激光标记的粘合膜。 释放层对于激光辐射基本上是透明的。 还公开了具有多层激光标记的多层制品。
