Title:

LASER-PERSONALIZABLE SECURITY ARTICLES

Document Type and Number:

WIPO Patent Application WO/2012/162041

Kind Code:

A3

Abstract:

Laser-personalizable security articles include a multi-layer security document and an optically transparent processing tape. 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. The optically transparent processing tape sufficiently wets out on the microstructured surface to render the microstructured surface invisible to a writing laser.
