Abstract: A highly refractive embossing lacquer for producing micro-optic arrangements which contains at least one binding agent which has at least one radiation-curing compound system having one or more organic compounds. The highly refractive embossing lacquer has at least a portion of the organic compounds of the radiation-curing compound system having molecules with at least one polarizable element, so that a polymeric material with a refractive index of greater than 1.5 is formed upon radiation curing. A security element which is produced with at least one micro-optic authenticity feature is also provided. The micro-optic authenticity features permit the production of security elements that are so thin that they can be easily incorporated into value documents.

Abstract: Proposed is a portable data carrier for use in a plurality of applications having a memory device containing at least one data field (21, 31) which can be accessed in several modes by applications realized in a card application device, and an access control device (15) for controlling the accesses to the data fields (21, 31). Each data field (21, 31) has a table (23, 24, 33, 34) assigned thereto which assigns an access right to each possible access mode. Each application accordingly has at least one access right assigned thereto. In the case of an access intent the access control device (15) checks whether the application intending the access has the access right necessary for the intended access.

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.
