description A security element is described includes a transparent first layer having a holographic surface structure, a first metal layer arranged on the first layer in a first pattern having transparent and non-transparent regions and a holographic surface structure, a second layer having a second holographic surface structure, and a second metal layer arranged on the second layer in a second pattern having transparent and non-transparent regions and a holographic surface structure. The, transparent regions of the first metal layer and the second metal layer are arranged to at least partly overlap each other and the non-transparent regions of the metal layers develop holographic effects on both sides of the security element which effects may be different. A process is described for making the security element, wherein an embossable radiation-sensitive polymer material is used to form the second layer.
