摘要： A security element (2) in the form of a laminate can be used for the authentication of a document (1). The laminate has at least a transparent protective layer, a transparent lacquer layer and an adhesive layer, the lacquer layer being arranged between the protective layer and the adhesive layer. An interface in the form of a reflection layer separates the adhesive layer and the lacquer layer. The interface is divided into regions of a pattern (25) with flat surface portions and with relief structures which are formed in the lacquer layer. The flat surface portions form background surfaces (3) providing flat mirror surfaces for light which is incident into the laminate, while the regions with the relief structures of a predetermined, optically effective structure depth form pattern elements (4). The relief structures of the pattern elements (4) absorb the incident light. In the reflected light of the reflecting background surfaces (3) the dark pattern elements (4) form a strong contrast and the pattern (25) is clearly visible. In directions other than that of the reflected light the contrast between the background surfaces (3) and the pattern elements (4) disappears so that a copier apparatus reproduces the background surfaces (3) and the pattern elements (4) as black surfaces.
摘要翻译： 层叠体形式的安全元件（2）可用于文件（1）的认证。 层压体至少具有透明保护层，透明漆层和粘合剂层，漆层布置在保护层和粘合剂层之间。 反射层形式的界面将粘合剂层和漆层分开。 界面被划分成具有平坦表面部分的图案（25）和形成在漆层中的浮雕结构的区域。 平坦表面部分形成背景表面（3），为入射到层压体中的光提供平坦的反射镜表面，而具有预定的有光学有效结构深度的浮雕结构的区域形成图案元件（4）。 图案元件（4）的浮雕结构吸收入射光。 在反射背景表面（3）的反射光中，暗图案元素（4）形成强烈的对比度，并且图案（25）清晰可见。 在反射光以外的方向上，背景表面（3）和图案元件（4）之间的对比度消失，使得复印机装置将背景表面（3）和图案元件（4）再现为黑色表面。

摘要： An optically variable surface pattern (1) contains relief structures (9.1; 9.2; 9.3) for producing at least two representations (2; 3; 4). The relief structures (9.1; 9.2; 9.3) have a period length (L) of at least five micrometers and are sawtooth-shaped. The relief structures (9.1; 9.2; 9.3) associated with different representations (2; 3; 4) have different angles of inclination (α;β;γ). The angles of inclination are so selected that the representations (2; 3; 4) can be perceived separately by a viewer on the one hand and on the other hand when producing a copy by means of a color photocopier they are all transferred onto the copy.

摘要： A label (1) made from a layer composite (15) includes at least one machine-readable diffractive bar code (3) consisting of narrow rectangular fields (4) occupied by the optically active structures and intermediate surfaces (5). The optically active structures which are covered by a reflection layer are embedded between layers of the layer composite (15). The diffractive relief structure used in the diffractive bar code (3) for the fields (4) diffracts and polarizes incident light and scatters the diffracted light into a half-space above the diffractive relief structure. A second diffractive relief structure differs at least in respect of the polarization of the polarizedly backscattered light with respect to the first diffractive relief structure. The second diffractive relief structure can be used for example for field surfaces of a second bar code in the bar code field (9) on the label (1) or for the intermediate surfaces (5). The light which is polarizedly backscattered at the diffractive bar code (3) can be detected by means of one of the known commercially available reading apparatuses for bar codes produced by printing. The bar code produced by printing can be used for individualizing the labels (1).

摘要： A security element in the form of a multi-layer film body with a security element and a process for the production of such a security element. The film body has a replication lacquer layer and a thin-film layer for producing a viewing angle-dependent color shift effect by interference. A first relief structure is shaped in a first region in the interface between the replication lacquer layer and the thin-film layer. That relief structure suppresses the production of the color shift effect by the thin-film layer so that the color shift effect is not present in the first region in which the first relief structure is provided and the color shift effect produced by the thin-film layer is present in a second region of the security element, in which the first relief structure is not provided.

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.

Light (11) which is incident on the plastic laminate (1) and which passes through a cover layer (4) of the plastic laminate (1) and through the shaping layer (5) is deflected in a predetermined manner by means of the optically effective structures (9). 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.
