Information page
An information page ( 1 ) of a security document, includes: an information part ( 3 ), on the upper or lower surface of which part of the information recorded on the information page ( 1 ) can be seen; and a flexible connecting part ( 2 ) with good bending strength for attaching the information page ( 1 ) to a security document. To ensure that detaching the information part and the connecting part from each other leaves visible marks, the connecting part ( 2 ) has a netlike structure, and the connecting part ( 2 ) is arranged to penetrate into the information part ( 3 ) in the immediate vicinity of the upper or lower surface of the information part.
1. An information page of a security document, comprising:
an information part, on the upper or lower surface of which at least a part of the information recorded on the information page can be seen; and
a flexible connecting part with good bending strength for attaching the information page to a security document, said connecting part having a netlike structure, and being arranged to penetrate into the information part in the immediate vicinity of the upper or lower surface of the information part such that the netlike structure of the connecting part sinks into the material of the information part.
2. The information page according to claim 1 , wherein the netlike structure of the connecting part partly protrudes from said upper or lower surface of the information part, into the immediate vicinity of which the connecting part penetrates.
3. The information page according to claim 1 , wherein the netlike structure of the connecting part comprises threads that form an angle of about 45° with a seam of the information part and the connecting part.
4. The information page according to claim 1 , wherein the connecting part comprises polyester; and material of the information part coming into contact with the connecting part comprises polycarbonate.
5. A method of manufacturing an information page of a security document, comprising:
forming an information part, on the upper or lower surface of which at least part of the information recorded on the information page can be seen,
attaching a flexible connecting part with good bending strength to the information part to attach the information page to the security document,
selecting as the connecting part a connecting part having a netlike structure that is arranged against the upper or lower surface of the information part; and
performing said attaching by laminating in such a way that at a raised temperature the connecting part is pressed against said upper or lower surface of the information part such that the netlike structure of the connecting part sinks into the material of the information part to achieve such an information page in which the connecting part penetrates into the information part in an immediate vicinity of the upper or lower surface of the information part.
6. The method according to claim 5 , wherein the method further comprises:
forming the information part by positioning at least two sheets, which are to be laminated to each other, one upon the other, at least one of the sheets being applicable to laser engraving;
arranging the connecting part having a netlike structure to at least partly overlap with the sheets to be laminated to each other; and
performing said laminating to attach said sheets to be laminated to each other and said connecting part together at one laminating stage.
7. The method according to claim 5 , wherein the method further comprises manufacturing said selected connecting part in such a way that the netlike structure of the connecting part comprises threads that form an angle of about 45° with a seam between the information part and the connecting part.
8. The method according to claim 5 , wherein the method further comprises making the information part of polycarbonate, and making the connecting part of polyester.
