Beschreibung
Zusammenfassung:	The invention relates to a security document (100) with a securing element (101) placed locally or on the entire surface of a laminated or non-laminated substrate, comprising at least a marking region composed of at least one printing ink layer containing optically variable interference pigments and fluorescent pigments and/or dyes or a printing ink layer containing optically variable interference pigments and being free of additives changing the absorption spectrum of the printing ink layer, the marking region comprising a laser marking applied by laser radiation, that is visually recognizable basing on an irreversible change of interference properties of the printing ink layer containing optically variable interference pigments and fluorescent pigments and/or dyes or printing ink layer containing optically variable interference pigments, and on a transformation, within the laser marking, of an original color demonstrating a change dependent on the observation angle into another color demonstrating no change dependent on the observation angle. Also, the invention relates to a method for producing a security document as well as the invention relates to a securing element placed on a laminated or non-laminated security document (100).
