Patent ID: 7295717

Claim:
A visually attractive article comprising (a) a base layer, (b) a revealing layer and upon superposition of said base layer and revealing layer, (c) a superposition image where the revealing layer comprises a revealing line grating, where the base layer comprises an item selected from the group of base band grating and modified sets of lines, where the base band grating comprises base bands that are repeated along one direction only, said base bands comprising a sequence of specific base band shapes, where said modified sets of lines are obtained by modifying initial sets of lines according to a shape elevation profile generated from a motif shape image, where in the case of a base layer comprising a base band grating, the superposition image comprises a band moiré image comprising moiré shapes which are transformed instances of the base band shapes, the transformation comprising at least an enlargement, and where in the case of a base layer comprising modified sets of lines, the superposition image comprises level lines of said shape elevation profile.
