The invention relates to a security covering structure for identity documents, for example identity cards, passports, credit cards visas or checks, which comprises a series of layers (1, 2, 3). On determined areas (11, 21, 31) of said layers, corresponding reflecting means (12, 22, 32) haven been deposited. The areas (11, 21, 31) are arranged in such a way that they don't overlap when seen in a direction perpendicular to the external surface of the structure. The first layer (1) includes a polyester sheet, and the second layer (2) is made of polyolefin. The invention also relates to a process for obtaining said structure. <IMAGE> |
