Zusammenfassung:In order to produce a data carrier, a substrate is printed with a printing ink and personalized by means of a laser. The printing ink is laser-active and is converted at least in regions during the personalization in such a way that, for example, a silver-grade pigment is formed which is readily visible only when the substrate is inclined. In particular, the printing ink has a comparatively small proportion of carbon black that is converted by the laser essentially without disturbing combustion and overall formation.
