The surface structure is formed in at least a first region of the film element (35) by a first diffractive surface relief (46) comprising a plurality of successive elements following a first envelope curve (47), wherein the elements respectively comprise an element surface (48) arranged substantially parallel to a base surface and at least one flank adjoining the adjacent element surface or surfaces, the element surfaces (48) of adjacent elements are spaced in a direction perpendicular to the base plane, with a first optical spacing or a plurality of the first optical spacing, wherein the first optical spacing is between 150 nm and 800 nm, preferably between 150 nm and 400 nm. The first envelope curve (47) has a spatial frequency of between 100 L/mm and 2000 L/mm and an optical depth of more than 450 nm and the relief shape and the spatial frequency of the envelope curve (47) are so selected that the incident light is diffracted into one or more first directions to represent a first item of information, the color value of which is further determined by the first optical spacing.

The first zones (85) each have a smallest dimension of less than 20 μm and the pattern formed from the first and second zones forms a diffractive optical system which diffracts the light transmitted through the second zones (86) to represent a first item of information.

    摘要: A diffractive security element has a half-tone image comprising diffractive structures in a reflection layer, which are embedded in a layer composite between a transparent embossing layer and a protective lacquer layer. The half-tone image is divided into image elements of at least one dimension less than 1 mm, wherein the surface of each image element is divided up into a background field and an image element pattern. The proportion of the image element pattern to the surface of the image element determines the surface brightness of the half-tone image at the location of the image element. The background field has a first diffractive structure from which the image element pattern differs by its light-modifying effect. Pattern strips of a width of up to 0.3 mm additionally extend over the surface of the half-tone image. The pattern strips occupy a small proportion of the surface of the background fields and/or the image element patterns and produce coloured strips on the half-tone image.

    摘要: A security element which is difficult to copy includes a layer composite which has microscopically fine, optically effective structures of a surface pattern, which are embedded between two layers of the layer composite. In a plane of the surface pattern, which is defined by co-ordinate axes x and y, the optically effective structures are shaped into an interface between the layers in surface portions of a holographically non-copyable security feature. In at least one surface portion the optically effective structure (9) is a diffraction structure formed by additive superimposition of a macroscopic superimposition function (M) with a microscopically fine relief profile (R). Both the relief profile (R), the superimposition function (M) and also the diffraction structure are functions of the co-ordinates x and y. The relief profile (R) is a light-diffractive or light-scattering optically effective structure and, following the superimposition function (M), retains the predetermined profile height. The superimposition function (M) is at least portion-wise steady and is not a periodic triangular or rectangular function. In comparison with the relief profile (R) the superimposition function (M) changes slowly. Upon tilting and rotation of the layer composite the observer sees on the illuminated surface portions light, continuously moving strips which are dependent on the viewing direction.

    摘要: The invention concerns an optical security element having a substrate layer, in which a first microstructure for producing a first optically perceptible effect is shaped region-wise in a surface region. The surface region is divided into microscopically fine pattern regions and a background region. The first microstructure is shaped in the pattern regions but not in the background region. The microscopically fine pattern regions in the surface region are arranged in the form of a moire pattern into which a concealed item of information which can be evaluated by means of an associated verification element is encoded as a security feature. The microscopically fine pattern regions are further substructured in accordance with a substructuring function which describes a microscopic substructuring, serving as a further security feature, of the moire pattern.

    摘要: The present invention relates to an optically variable element having surface portions with achromatic surface structures and different scatter, diffraction and reflection characteristics. The achromatic surface structures are combined with a thin-film structure, whereby upon turning or tilting the optically variable element, it is not the impression of a continuous color transition, but a defined, almost discrete color change that is produced for the viewer.
