The invention relates to a data carrier with an optically variable structure having an embossed structure with raised areas and a first coating contrasting with the surface of the data carrier. The embossed structure and the first 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 first coating is provided only in certain areas. Additionally, the optically variable structure has at least in partial areas a second coating likewise contrasting with the data carrier surface and disposed in overlap with the first coating at least in partial areas.

Support de données à structure optiquement variable qui comporte une structure gaufrée pourvue de zones en relief et un premier revêtement contrastant avec la surface du support de données. La structure gaufrée et le premier revêtement sont combinés de manière telle qu'au moins certaines parties du revêtement sont totalement visibles lorsqu'elles sont regardées verticalement, mais cachées lorsqu'elles sont regardées de biais, si bien qu'il en résulte un effet de basculement lorsque lesdites parties sont regardées en alternance verticalement et de biais. Le premier revêtement n'est présent que sur certaines parties. Ladite structure optiquement variable possède en outre au moins sur certaines parties un second revêtement contrastant également avec la surface du support de données, ce second revêtement recouvrant le premier revêtement, au moins sur certaines parties.
