摘要： A decorative foil is in the form of a layer composite structure (1) and comprises at least a transparent base foil (2), a transparent cover layer (4) and a transparent dielectric layer (3) arranged between the base foil (2) and the cover layer (4). When the decorative foil serves as a lamination foil for a substrate (5) the material of the cover layer (4) is an adhesive. A reflective metallic layer (6) is arranged at least in surface portions between the dielectric layer (3) and the cover layer (4) and optionally a metal film (11) is also arranged on the side of the dielectric layer (3) facing the base foil (2). General items of information shown by the decorative foil are produced by means of modulation of the thickness (s) of the dielectric layer (3). Transparent locations (7) form individual items of information, wherein the transparent locations (7) are produced with a laser beam (19) by perforating the metal layer (6; 11). Besides being used as a lamination foil the decorative foil can also be used as a packaging foil.

摘要： 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 μm and 100 μm. The structure elements have side faces which are covered by the reflection layer and which include an angle of inclination of 45°, 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.

Shaped in the surface of at least one of the surface elements is a diffraction structure which is produced by a superimposition of a linear asymmetrical diffraction grating (24) with a matt structure. The linear asymmetrical diffraction grating (24) has a spatial frequency from the range of values of between 50 lines/mm and 2,000 lines/mm. The matt structure has a mean roughness value from the range of between 20 nm and 2,000 nm and at least in one direction a correlation length of between 200 nm and 50,000 nm.

摘要： A security element is embedded in a layer composite of plastic material and has reflecting, optically variable surface patterns which can be visually recognized from predetermined observation directions and which are formed from a mosaic of surface elements occupied by optically active structures. A part of the surface pattern is additionally covered by a regularly arranged matrix of unit cells. Each unit cell is occupied by a single elementary surface or a group of identical surface portions that contain optically active structures which are independent of the mosaic of the surface pattern. The arrangement of the elementary surfaces and the surface portions in the matrix form an item of concealed information which is not perceptible to the naked eye, in the form of graphic or alphanumeric characters which however are reproduced in a color photocopy with a color or gray value contrast which is perceptible to the naked eye.

摘要： A surface pattern is made up of surface elements (1 to 7) which are arranged in a mosaic-like fashion and which have microscopic relief structures. The surface elements (2 to 6) which are divided at least into first and second surface portions (8; 9) have in the first and second surface portions (8; 9) asymmetrical diffraction gratings (12; 13) with an optical diffraction effect, wherein in each divided surface element (2 to 6) adjacent first surface portions (8) are separated by at least one second surface portion (9). The grating vectors of the asymmetrical diffraction gratings (12) of the first surface portions (8) of all divided surface elements (2 to 6) have the same first value in respect of azimuth and the asymmetrical diffraction gratings (13) of the second surface portions (9) of all divided surface elements (2 to 6) have the same second value in respect of azimuth. The divided surface elements (2 to 6) are arranged in accordance with their surface proportion value AN in the mosaic of all surface elements (1 to 7). The surface proportion value AN of the N-th divided surface element is the relationship of the sum of all first surface portions (8) to the total area of all first and second surface portions (8; 9).

摘要： A surface pattern (1) has N visually recognizable patterns which are composed of optically diffractive, microscopically fine relief structures, plane mirror faces or absorbing or scattering structures. The N patterns share at least one independent common surface element (11). The surface element (11) is subdivided into surface parts and has an arrangement of the surface parts which is independent of the N patterns, which has a predetermined structure, and which is not recognizable to the naked eye. A single microscopically fine diffraction structure or a structure which has an absorbing or scattering property or is a plane mirror is applied to each surface part. The relief structures, diffraction structures and other structures are embedded in a plastic laminate (20) and can have their optical performance enhanced by a reflection layer (21). The surface pattern (1) is applied as a security element to a document (2) and allows the document (2) to be identified by machine in a reading machine.
