Embodiment Construction

[0163] figure 1 A multilayer body 100 is shown, in which a functional layer 2, a replication layer 3, a structured aluminum first layer 3m, and two differently colored, transparent photosensitive layers 12a that have a matching relationship with the first layer 3m, 12b is placed on the carrier film 1. The functional layer 2 is a layer that is mainly used to increase the mechanical and chemical stability of the multilayer body, but can also be adjusted to produce an optical effect in a known manner, wherein it can also be provided that the layer is composed of a plurality of sublayers. This layer can also be made of wax or in the form of a release layer. However, it is also possible to omit this layer and place the replication layer 3 directly on the carrier film 1. It can also be provided that the carrier film 1 itself is in the form of a replication layer.

[0164] The multilayer body 100 may be a part of a conversion film, such as a thermal relief layer applied to a substrate ...

Abstract

Various methods are described for producing multi-layer bodies having at least one partially formed functional layer and at least one further partially formed layer, and the multi-layer bodies which are produced in this way are also described. The multi-layer body has at least one partially formed functional layer in register with at least one further partially formed layer which preferably complement one another to form a geometric, alphanumeric, visual, graphic or figurative coloured design.

Description

Technical field [0001] The present invention relates to a method of manufacturing a multilayer body having at least one partially formed functional layer, the functional layer having a matching relationship with at least one other partially formed layer, and also relates to the obtained Multi-layer body. In particular, the invention also relates to a security element for security documents and securities having such a multilayer body. Background technique [0002] Optical security elements are often used to make it difficult to copy and abuse files or products, and to prevent such copying and abuse as much as possible. Therefore, optical security elements are often used to protect documents, bank securities, credit cards, cash cards, ID cards and passes, packaging, etc. It is known to use optically variable elements that cannot be reproduced by conventional reproduction means. It is also known to provide security elements with structural metal layers in the form of text, logos or...
