The invention relates to a structure (1) comprising: a fibrous layer (2a, 2b); a substructure (3) having a translucent region; a watermark or pseudo-watermark (8a, 8b) carried by the fibrous layer and at least partially superposing the translucent region of the substructure, in such a way that the watermark or pseudo-watermark is observable in transmitted light through the structure, in the translucent region of the substructure, only from that face of the structure which is adjacent to the fibrous layer; and an integrated microcircuit device (4, 10) for communication with and/or without a contact.
L'invention concerne une structure (1) comportant: une couche fibreuse (2a, 2b); une sous-structure (3) comportant une région translucide; un filigrane ou pseudo-filigrane (8a, 8b) porté par la couche fibreuse et se superposant au moins partiellement à la région translucide de la sous-structure, de telle sorte que le filigrane ou pseudo-filigrane ne soit observable en lumière transmise à travers la structure, au niveau de la région translucide de la sous-structure, que de la face de la structure adjacente à la couche fibreuse, et; un dispositif à microcircuit intégré (4, 10) communication sans contact et/ou avec contact.
