摘要： The invention relates to a value document, especially a banknote, having a sequence of layers into which visually and/or mechanically perceptible identifiers in the form of patterns, letters, numbers or images are introduced by the action of laser radiation. According to the present invention, the sequence of layers includes a marking layer (22) composed of an ink mixture (24, 26) exhibiting a laser-radiation-absorbing mixture component (26) and a laser-radiation-transparent mixture component (24), the identifiers being visually and/or mechanically perceptible due to an irreversible change in the optical properties of the ink mixture (24, 26), effected by the action of the laser radiation.

摘要： A security element for a data carrier (1) includes a translucent substrate (3) which has a first partial area (4) with a first ink layer and a second partial area (5) with a second ink layer different from the first ink layer, wherein the first and second partial area, upon viewing in incident light, form a contiguous total area and produce a substantially identical visual impression, and wherein the first partial area, upon viewing in transmitted light, produces a brighter visual impression compared to the second partial area.
