摘要 A security element (1) for security papers, documents of value or the like, having a substrate (3) the upper face (6) of which is height-modulated, and has a multilayer structure (7) which acts as a color filter. The structure is formed on the height-modulated upper face (6) and is likewise height-modulated as a result, and includes a first layer (8), a second layer (9) of dielectric material formed thereon and a third layer (10) formed on the second layer (9), wherein the first and third layer (8,10) are each formed from a dielectric material having a higher refractive index than that of the second layer (9), or in each case from a metal or semi-metal material.
