Abstract (en)
[origin: EP1983473A1] Data carrier into which markings are introduced using a laser beam, said markings being visible as laser-generated irreversible changes of the optical characteristics of the data carrier. The data carrier comprises a laser-sensitive layer (20) that is opaque in the visible spectrum and is combined with a securing layer (22) that is metalized in at least a partial area. The markings (30, 32) are introduced simultaneously and with exactly matching registers in the laser sensitive layer and the metalized area (24) of the securing layer. An independent claim is made for a method for manufacturing an inventive data carrier.
