A security element comprises a diffractive or reflective relief structure 198a at least in first partial areas P1 of the region; a reflection enhancing material 197 present at least in the first partial areas of the region and being disposed on and following the contours of the diffractive or reflective relief structure; and a light absorbing material 192 provided in second partial areas P2 of the region which do not overlap the first partial areas. The first partial areas being arranged between the second partial areas such that a half-tone or screened pattern is formed by the reflection enhancing material and the light absorbing material in combination and is exhibited across the region. A non-opaque layer of iridescent amplitude interference material 193 is applied at least over the second partial areas of light absorbing material. In the areas of the light absorbing material, the visual effect of the iridescent amplitude interference material is visible, and in the intervening areas where the reflection enhancing material and the diffractive or reflective relief structure are present, the visual effect of the diffractive or reflective relief structure is visible, such that the two visual effects appear superimposed on one another across the region. |
