Abstract

L'invention concerne un support de données (10) comportant deux images de motifs différentes qui sont visibles à partir de faces opposées du support de données, à savoir un motif de face avant (22) et un motif de face arrière (32). Selon l'invention, le support de données (10) a une construction multicouche comportant une couche à motifs supérieure (52), une couche à motifs inférieure (62), et une couche intermédiaire (40) qui est agencée entre les couches à motifs (52, 62) et qui est translucide au moins dans certaines régions. En outre, un sous-motif (22A, 22B) respectif du motif de face avant (22) est agencé dans les couches à motifs supérieure et inférieure (52, 62), les deux sous-motifs (22A, 22B) se complétant l'un l'autre de façon à former le motif de face avant (22) lorsque le support de données est vu depuis la face avant et/ou chaque sous-motif (32A, 32B) du motif de face arrière (32) étant agencé dans les couches à motifs supérieure et inférieure (52, 62), et les deux sous-motifs (32A, 32B) se complétant l'un l'autre de façon à former le motif de face arrière (32) lorsque le support de données est vu depuis la face arrière. Chacune des couches à motifs supérieure et inférieure (52, 62) est constituée d'une encre d'impression modifiée par laser, les informations de motif de celle-ci qui sont produites par application laser et qui forment le motif de face avant (22) et le motif de face arrière (32) n'étant visibles qu'en vue de dessus et n'étant pas visibles en lumière transmise.
