DATA CARRIER COMPRISING AN OPTICALLY VARIABLE ELEMENT |
摘要 |
The invention relates to a data carrier comprising an optically variable structure which is provided with an embossed structure having raised areas and a first coating that contrasts with the surface of the data carrier. The embossed structure and the first coating are combined in such a way that at least some parts of the coating are entirely visible when viewed from a vertical position while being covered when viewed from an angle such that a tilting effect is created during alternating viewing from a vertical position and from an angle. Only some areas are provided with the first coating. At least some zones of the optically variable structure additionally comprise a second coating which also contrasts with the surface of the data carrier and is arranged in such a way that said second coating overlaps with the first coating at least in some areas. |
