Abstract: The invention concerns a security element having a magnetic coding consisting of magnetic coding elements. At least one of the magnetic coding elements has a grid-shaped magnetic region which is formed by a plurality of mutually parallel grid strips made of magnetic material which respectively have a magnetic anisotropy. The grid strips lead, through their magnetic anisotropy, to the magnetization direction of the coding element being able to differ from the direction of the applied magnetic field. Since the resultant magnetic signals that the grid-shaped magnetic regions deliver cannot be simulated by conventional magnetic regions, said coding elements increase the anti-forgery security of the security element.

Abstract: An optically variable surface pattern is made available, having at least two partial areas with reflection elements, wherein the reflection elements of the first partial region on the one hand and the reflection elements of the second partial region on the other hand reflect impinging light in different reflection directions. The first partial region is so covered with a first glazing ink layer that a viewer, upon a change of the viewing angle at which the viewer views the optically variable surface pattern, sees the first partial region glow in a first color upon reaching a first viewing angle. The second partial region glows in a second color that is different from the first color upon reaching a second viewing angle.
