Definitions
- the invention relates to a security element with a substrate and at least one microimage arrangement and at least one focusing layer which interacts with the microimage arrangement and has an arrangement of focusing elements, the at least one microimage arrangement comprising at least one relief structure, the microimage arrangement having a visible optical image when viewed through the focusing layer effect created.
- Such security elements are usually used to increase the counterfeiting security of securities or security papers, such as banknotes, identity cards, credit cards, ATM cards, tickets, etc.
- the object of the present invention is to increase the counterfeit security of the known security elements.
- the at least one microimage arrangement comprises at least one color-shifting layer arranged on the at least one relief structure and having a color-shifting effect recognizable through the focusing layer.
- the resolution according to the invention makes it possible for the microimage arrangement to only become recognizable in interaction with the focusing elements and without the focusing elements only the color-shifting layer would be perceptible as a uniform layer with a uniform color impression.
- the invention makes it possible to create a security element that is very difficult to counterfeit.
- the solution according to the invention also enables a high degree of customization, or a large variety of design options. This is accompanied by a significant increase in protection against counterfeiting.
- a layer is applied to something
- the phrase "a layer is applied to something" should be understood to mean that the layer may be applied directly, or there may be another or there may be several intermediate layers.
- one or more intermediate layers can be arranged between the layers described in this document. It is therefore not absolutely necessary for the layers described to contact one another.
- the term layer in this document is to be understood in such a way that a layer can be made up of only a single layer or also of a number of partial layers or partial layers.
- the substrate preferably has a thickness of between 5-700 ⁇ m, preferably 5-200 ⁇ m, particularly preferably 5-125 ⁇ m, in particular 10-75 ⁇ m.
- the focusing elements are designed as microlenses, in particular as microlenses embossed in an embossing lacquer layer.
- the embossing lacquer layer, with the microlenses formed therein can have a thickness of, for example, 0.1 ⁇ m to 300 ⁇ m, in particular from 0.1 ⁇ m to 50 ⁇ m.
- the focusing elements designed as microlenses can also be made of a ther moplastic material.
- a so-called reflow method can be used here. This technique comprises the steps of: defining an insular structure in or with a thermoplastic material such as a resin, eg by photolithography in a light-sensitive resin-like photoresist, or applying the material to a substrate, eg by printing, and then heating the material. In doing so, surface tension pulls the island of material into a spherical cap with a volume equal to that of the original island before melting, forming a microlens.

It is also possible for only parts of an image to lie under a lens or a focusing element and the magnification and the interaction of the lenses then a macroscopic image is constructed.
- the focusing elements do not necessarily have to lead to an enlargement. It is also possible to use only the refraction of light from the focusing elements to display an image sequence by tilting, in which case an image sequence can be defined by nested microimages. In this case, the focusing elements and the micro-image arrangement can produce a lens raster image (“lenticular raster image”).
- a very good contrast, particularly in terms of colour, of the microimage arrangement and a significantly improved perceptibility of the same can be achieved by influencing the color-shifting layer, in particular its thickness, in the case of thin-film structures in particular the spacer layer, through the structures of the microimage arrangements, resulting in a color change of the color-shifting layer varies precisely with the structure.
