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.
