  • Patent number: 10017001
    Abstract: Laser-personalizable security articles include multi-layer security documents. The multi-layer security document includes an optically transparent cover layer, a composite image and an imagable layer adjacent to the cover layer. The first surface of the cover layer is at least partially a microstructured surface, where the microstructured surface forms microlenses or a lenticular surface. The composite image is made by a collection of complete or partial images viewed through the microstructured surface of the cover layer. The composite image is located on or within the second surface of the cover layer. The imagable layer is a laser imagable layer. When imaged, a personalized second composite three dimensional image is created on or in the imagable layer.
