Abstract (en)
[origin: WO2005108110A1] The invention relates to a value document (10), particularly a banknote, comprising a sequence of layers into which visually and/or mechanically recognizable markings are introduced in the form of patterns, letters, numbers, or images under the effect of laser radiation. According to the invention, the sequence of layers encompasses a marking layer (22) that is composed of an ink mixture (24, 26) comprising a component (26) absorbing the laser radiation and a component (24) which is transparent to the laser radiation. The markings are visually and/or mechanically recognizable as a result of an irreversible change in the optical characteristics of the ink mixture (24, 26), said irreversible change being caused by the laser radiation.
