Title:

VALUABLE DOCUMENT WITH AN OPTICALLY VARIABLE STRUCTURE (VARIANTS)

Document Type and Number:

WIPO Patent Application WO/2013/002680

Kind Code:

A3

Abstract:

The valuable document comprises a coating in the form of a printed raster that is made up of at least one colour which is different from the colour of the main document. The document also comprises a three-dimensional raster arranged relative to the coating so that the three-dimensional raster is at least partially disposed on the coating, is oriented substantially parallel to the lines of the printed raster and together with the coating forms a latent image which is not discernible when the document is viewed at a right angle. At least a portion of the lines of the three-dimensional raster has an asymmetric cross-section profile with an aspect ratio of not less than 1:1.25, as a result of which the latent image becomes visible in the form of coloured elements or a single-coloured region in the event of a change in the viewing angle. In the event of a 180° change in the viewing direction without any change in the viewing angle, a change in the optical density or in the colour gamut of at least a part of the latent image results. The invention makes it possible to increase the protection against counterfeiting of a valuable document with optically variable images and makes it possible for an untrained user to carry out a visual authenticity check.
