Abstract
A data carrier with an optically variable element has a layer regularly reflecting incident light and including interruptions. A diffusely scattering layer is disposed on the regularly reflecting layer so as to be visible through at least one interruption to provide at least one optically recognizable marking based on the differences in the reflectivities of the two layers at different viewing angles.
