The invention relates to a security document (1) comprising at least one security feature and to a method for the production thereof. The invention also relates to, in particular, a security document (1) with at least one security element, comprising a document body with at least one diffraction layer (2) that comprises on a top side, a diffraction surface structure (4) that is embodied as an optically thin projection hologram as the at least one security element. In the document body, at least one suppression structure is formed or arranged behind the diffraction surface structure when viewed from the top side (6) of the at least one diffraction layer (2), in order to minimise an oriented reflection of a reconstruction light (9, 10) back through the top side of the diffraction layer (2), transmitted by the diffraction structure (4) and appearing on the top side (6) of the diffraction layer (2) for reading out the diffraction surface structure (4). |
