The invention relates to a data carrier with an optically variable structure having an embossed structure and a coating contrasting with the surface of the data carrier. The embossed structure and the coating are so combined that at least parts of the coating are completely visible upon perpendicular viewing but concealed upon oblique viewing so that a tilt effect arises upon alternate perpendicular and oblique viewing. The coating is executed uniformly and the embossed structure is divided into partial areas where different partial embossed structures are provided.
L'invention concerne un support de données (1) ayant une structure optiquement variable (2) qui est composée d'une structure d'estampage et d'un revêtement, lequel contraste avec la surface du support des données (1). La structure d'estampage et le revêtement sont combinés de telle façon qu'au moins certaines parties du revêtement soient parfaitement visibles si l'on observe le support de face mais soient masquées si on l'observe sous un certain angle. Ainsi, en regardant alternativement de face et sous un certain angle, on obtient ainsi un effet de basculement. Le revêtement est réalisé de façon uniforme et la structure d'estampage est subdivisée en zones partielles correspondant à des structures d'estampage partielles.
