The invention relates to an integral layered structure for identity documents. The invention consists of a central structure (Ec1-Ec4) comprising thermolaminated layers having at least one face which is protected by a cover. The invention is characterised in that a zone-based metallic hologram (Hdmz) is provided on at least the front face of the central structure (Ec1-Ec4), which can be customised using a laser beam and which is stripped by means of either: gradual stripping with the application of successive corrosive stamps; or stripping using the laser beam in order to vaporise and eliminate the unwanted metallic deposit zones in accordance with the desired customisation, such as to transparentize around the contour of the laser-engraved image as well the clear zones of same. The invention is suitable for documents, identity cards, credit cards, passports, visas and bank notes. |
