Abstract
A security document has a carrier element which has a surface with a principal plane and a personalization region. A personalization layer is applied to the surface, such that the surface of the carrier element in the personalization region is configured with a plurality of structure elements uniformly aligned with each other and raised with respect to the principal plane. The structure elements of the plurality of structure elements are configured immediately adjacent to each other and the structure elements are configured with a center distance between vertical axes of the respective structure elements of less than 250 μm.
Claims14
A security document having a carrier element which has a surface with a principal plane and a personalization region, wherein in the personalization region a personalization layer is applied to the surface,
- wherein the surface of the carrier element in the personalization region is configured with a plurality of structure elements uniformly aligned with each other and raised with respect to the principal plane,
- wherein the structure elements of the plurality of structure elements are configured immediately adjacent to each other and wherein the structure elements are configured with a center distance between vertical axes of the respective structure elements of less than 250 μm;
- wherein the personalization layer is applied only with colorful color particles defined as being without black particles;
- wherein a black portion comprising black particles is integrated into the interior of the carrier element to define at least a contour of a personalization image;
- wherein the personalization layer is disposed on the structural elements such that the structural elements are at least partially covered by the colorful color particles;
- wherein a respective structure element of the plurality of structure elements is configured at least partly transparent;
- wherein a respective structure element of the plurality of structure elements is configured as an optical lens;
- wherein the colorful color particles of the personalization layer and the black portion integrated into the carrier element together form the personalization image, the personalization image being an image of a human face.
A method for manufacturing a security document with a wear-protected personalization layer, comprising the steps of:
- a) supplying a carrier element with a surface and a principal plane;
- b) determining a personalization region of the surface with a plurality of structure elements which are uniformly aligned with each another, immediately adjacent to each other and raised with respect to the principal plane, with a center distance between vertical axes of the respective structure elements of less than 250 μm;
- c) applying the personalization layer onto the surface in the personalization region;
- and
- d) supplying the security document having the carrier element and the applied personalization layer;
- wherein a respective structure element of the plurality of structure elements is configured at least partly transparent;
- wherein the personalization layer is applied only with colorful color particles defined as being without black particles;
- wherein a black portion comprising black particles is integrated into the interior of the carrier element to define at least a contour of a personalization image;
- wherein a respective structure element of the plurality of structure elements is configured as an optical lens;
- wherein the colorful color particles of the personalization layer and the black portion integrated into the carrier element together form the personalization image, the personalization image being an image of a human face.
