Abstract
Abstract A data carrier with an optically variable structure is described having an embossed screen which is combined with a coating contrasting with the surface of the data carrier in such a way that different optically variable effects occur at different angles. Embossed screen and/or coating are executed in such a way that especially striking or additional effects occur which are suitable for determining the authenticity of the data carrier but cannot be reproduced, or reproduced true to the original, with the help of copying machines.

Claims Analysis
Total Claims: 18
Claim 1
Independent Claim
192 words
A data carrier with an optically variable structure verifying the authenticity of the data carrier and having a first embossed structure which is combined with a first coating contrasting with the surface of the data carrier in such a way that at least partial areas of the coating are visible upon perpendicular viewing but concealed upon oblique viewing from a predetermined viewing direction so that a tilting effect occurs upon alternate perpendicular and oblique viewing, wherein the optically variable structure is divided into at least two areas, and wherein the first coating and the first embossed structure are disposed in a first one of said at least two areas, and a second embossed structure different from the first embossed structure and combined with a second coating different from the first coating and contrasting with the surface of the data carrier in such a way that at least partial areas of the second coating are visible upon perpendicular viewing but concealed upon oblique viewing from a predetermined viewing direction so that a tilting effect occurs upon alternate perpendicular and oblique viewing is present in the second one of said at least two areas.
Claim 2
Dependent Claim
192 words
A data carrier with an optically variable structure verifying the authenticity of the data carrier and having a first embossed structure which is combined with a first coating contrasting with the surface of the data carrier in such a way that at least partial areas of the coating are visible upon perpendicular viewing but concealed upon oblique viewing from a predetermined viewing direction so that a tilting effect occurs upon alternate perpendicular and oblique viewing, wherein the optically variable structure is divided into at least two areas, and wherein the first coating and the first embossed structure are disposed in a first one of said at least two areas, and a second embossed structure different from the first embossed structure and combined with a second coating different from the first coating and contrasting with the surface of the data carrier in such a way that at least partial areas of the second coating are visible upon perpendicular viewing but concealed upon oblique viewing from a predetermined viewing direction so that a tilting effect occurs upon alternate perpendicular and oblique viewing is present in the second one of said at least two areas.
