Abstract
A security element for manufacturing value documents, such as bank notes, checks or the like, has an upper side on which there is formed a microcavity structure that has a multiplicity of adjacent microcavities configured as retroreflectors, wherein on the microcavities there is formed a structure causing a color effect. The microcavities are respectively configured such that they have a first region in which radiation incident on the upper side is singly reflected, and a second region in which radiation incident on the upper side is multiply reflected. The structure causing the color effect has a dispersion dependent on the angle of incidence, so that radiation singly reflected at the first region shows a different color effect, when viewed from the upper side, than radiation multiply reflected at the second region.
