Definitions
- the invention relates to a method for producing a multilayer body having a carrier layer and a single-layer or multi-layer decorative layer formed on and / or in the carrier layer, as well as a multilayer body
- optical security elements are often used to make it difficult to copy documents or products to prevent their misuse, especially counterfeiting. How to find optical security elements
- optically variable elements As optical security elements which can not be duplicated by conventional copying methods. It is also known security elements with a structured
