Embodiment Construction

[0030] figure 1 An example of an identity document 10, which is a passport in this case, includes a security sheet 11 that is a data page in this case, and the security sheet 11 is stitched to a plurality of visa pages 13 and a cover along a seam 12 (Not shown). The visa page 13 is usually made of a fibrous substrate such as paper, and may include several security features such as security threads, security fibers, and watermarks.

[0031] As in figure 2 As shown in more detail in, the security sheet 11 includes a plastic substrate 14 having a first outer surface 15 and a second outer surface 16. Each of the first and second outer surfaces 15, 16 is preferably substantially flat and planar. The plastic substrate 14 is formed of a plurality of layers which are fused together into a substantially non-layered or monolithic structure. The plastic forming the plastic substrate 14 may be a thermoplastic polymer, such as polycarbonate, polyester, polyethylene, polypropylene, or polyv...

Abstract

The present disclosure provides a security sheet (11) for an identity document (10). The security sheet (11) comprises a plastic substrate (14) formed from a plurality of plastic layers (34). The plastic substrate (14) comprises a plurality of windows (60) and each window (60) has a maximum width in the range of from approximately 0.5 mm to approximately 10 mm. The present invention is further directed to an identification document (10) comprising the security sheet (11), a plurality of such identity documents (10) and a method of manufacturing the security sheet (11).

Description

Technical field [0001] The present invention is directed to a security sheet for identification documents, which includes a plurality of windows in a plastic substrate. The present invention is also directed to an identity document including the security sheet, a plurality of such identity documents, and a method of manufacturing the security sheet. Background technique [0002] Security documents and brochures such as passports, passbooks, identity documents, certificates, licenses, checkbooks, etc. usually include one or more security pages on which information is provided. For example, a passport booklet usually includes a cover and multiple internal visa pages in between. Usually, the visa page is made of paper with a weight of about 85gsm and stitched together along the seam. The cover is adhered to the outside of the visa page and thereby protects the suture. [0003] At least one security sheet or data page is provided in the booklet, and is usually the second or penultim...
