Claim Text:
1. A laser-personalizable security article comprising: a multi-layer security document, the multi-layer security document comprising: an optically transparent cover layer with a first surface, a second surface, and a thickness between the first surface and the second surface, the first surface being at least partially a microstructured surface, having a refractive index between 1.45 and 1.55, wherein the microstructured surface forms microlenses or a lenticular surface; a composite image, wherein the composite image comprises a collection of complete or partial images located on the second surface of the cover layer such that when viewed through the microstructured surface of the cover layer, the collection of complete or partial images forms the composite image; and an imagable layer adjacent to the second surface of the cover layer, wherein the imagable layer comprises a laser imagable layer; and an optically transparent, removable, conformable layer, wherein the removable, conformable layer comprises a processing tape wherein the tape comprises and optically transparent backing; and an optically transparent pressure sensitive adhesive layer at least partially coated on the backing, wherein the pressure sensitive adhesive sufficiently wets out on the microstructured surface to render the microstructured surface invisible to a writing laser and the optically transparent, removable, conformable laver has a refractive index in the range of 1.45-1.55.
