Abstract: Two film webs (1), (2) (in each case transfer film or laminating film) with a carrier film (11) and decorative layer (14), in particular metal layer and/or color layer (14), are to be joined to each other. Instead of using a conventional adhesive tape with cold-setting adhesive as hitherto, in the present case a hot-melt adhesive or an adhesive which can be cured using (UV) radiation is used. For example, using hot stamping, a carrier (63) with a PET layer (64) and an adhesive (65) can be applied which joins together two film webs (1, 2) which are in abutment.

Abstract: A layer composite of plastic material forms a retroreflector and includes at least one transparent structure layer, a protective layer and a reflection layer enclosed at the common interface between the structure layer and the protection layer. A relief structure formed by substantially identically shaped three-dimensional structure elements is formed in the reflection layer. At their base surfaces the structure elements are of lateral dimensions in the range of between 1 nullm and 100 nullm. The structure elements have side faces which are covered by the reflection layer and which include an angle of inclination of 45null, with a free surface of the layer composite. The relief structure is additively superimposed with a microstructure in at least one surface element. The microstructure has a preferred direction and influences the quality of the reflection action of the layer composite. The retroreflector is suitable for the production of machine-readable optical markings.

Abstract: A method for producing security elements, security elements, a security document with at least one security element as well as a transfer film with at least one security element, wherein a three-dimensional object is recorded and a surface profile of the three-dimensional object, described by a function F(x,y), is determined, wherein the function F(x,y) describes the distance between the surface profile and a two-dimensional reference surface spanned by co-ordinate axes x and y at the co-ordinate points x and y. A first microstructure is determined in such a way that the structure height of the first microstructure is limited to a predetermined value smaller than the maximum distance between the surface profile and the two-dimensional reference surface, and the first microstructure provides an observer with a first optical perception which corresponds to the surface profile of the three-dimensional object described by the function F(x,y).
