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.
