The security element (1) comprises a layer based on liquid crystalline materials, a lacquer layer on which the liquid crystalline layer (5) is applied, a function layer on which the lacquer layer is applied, and an adhesive layer. The lacquer layer is unstructured and consists of a lacquer (3) that is free from liquid crystals and is inert against the liquid crystalline layer. The lacquer is solvent free and the lacquer layer has a layer thickness of 2-3 mu m. The lacquer is radically or cationically hardened. The security element (1) comprises a layer based on liquid crystalline materials, a lacquer layer on which the liquid crystalline layer (5) is applied, a function layer on which the lacquer layer is applied, and an adhesive layer. The lacquer layer is unstructured and consists of a lacquer (3) that is free from liquid crystals and is inert against the liquid crystalline layer. The lacquer is solvent free and the lacquer layer has a layer thickness of 2-3 mu m. The lacquer is radically or cationically hardened. The function layer is non-inert against the liquid crystalline layer and is a further liquid crystalline layer. The security element has a bonding agent between the liquid crystalline layer and the lacquer layer, and has a stratified layer construction with further function layer. The further function layer is reflecting layer, a layer with optical diffraction effect, an interference layer, a layer containing reflecting, magnetic, electrically conductive, luminescent material, and a printed ink layer. The lacquer layer is applied between the liquid crystalline layer and the further function layer. Independent claims are included for: (1) a method for the production of a security element for safeguarding the authenticity of a value object; (2) a transfer band having security paper or a value document; and (3) a value document such as security paper. |
