The invention concerns a multilayer structure such as a booklet cover paper, in particular for a passport. It comprises a radio frequency identification device (31, 32) having a chip (31), the latter being housed in the thickness of the multilayer structure without creating excess thickness, the materials constituting the various layers of the multilayer structure being selected, as well as the thickness of said layers, such that the cover (20) is resistant to mechanical and thermal impacts, in particular so that it can be subjected to a graining and/or jacketing process by deposition of a heat-transfer film under pressure and/or by lamination when security films are deposited thereon.
L'invention est relative à une structure multicouche telle qu'un papier couverture de livret, notamment de passeport. Elle comporte un dispositif d'identification radiofréquence (31, 32) ayant une puce (31), celle-ci est logée dans l'épaisseur de la structure multicouche sans générer de surépaisseur, les matériaux constituant les différentes couches de la structure multicouche sont choisis, ainsi que l'épaisseur desdites couches, de manière à ce que la couverture (20) soit résistante aux chocs mécaniques et thermiques, notamment puisse subir un traitement de grainage et/ou d'enjolivure par dépôt d'un film par transfert à chaud et sous pression et/ou de lamination lors de dépôts de films de sécurité.
