Abstract
Abstract The invention relates to an identification document, such as a passport or the like, which consists of a plurality of sheets bound into a book at a seam. At least one of the sheets forms a data sheet provided with information and consisting at least of two layers, at least one of the layers being transparent. The format of the layers is selected so that they protrude beyond the area of the seam thereby ensuring a connection of the data sheet with the other sheets of the identification document in the area of the seam. The layers are connected into an inseparable laminate in the area of the information but do not stick together in the area of the seam.

Claim 7
Dependent Claim
37 words
The identification document of claim 4, wherein the format of the cover foil corresponds to the format of a double page of the identification document and the seam is disposed in the middle of said double page.
Claim 8
Dependent Claim
25 words
The identification document of claim 4, wherein the format of the inlay layer corresponds to or is smaller than the format of the cover foil.
Claim 9
Dependent Claim
19 words
The identification document of claim 4, wherein the inlay layer is provided with a cover foil on both sides.
Claim 10
Dependent Claim
18 words
The identification document of claim 4, wherein the inlay layer consists of paper or an opaque plastic foil.
Claim 11
Dependent Claim
19 words
The identification document of claim 3, wherein the plastic foils consist of different plastic materials and contain different additives.
Claim 12
Dependent Claim
28 words
The identification document of claim 3, wherein the plastic foils are selected from the group consisting of polycarbonate (PC), glycol modified polyethyleneterephthalate (PETG) and high deflection temperature (HDT).
Claim 13
Dependent Claim
16 words
The identification of claim 1, wherein the seam is formed by a sewn-in thread or gluing.
Claim 14
Dependent Claim
19 words
The identification document of claim 1, wherein the data sheet has user-related data which are incorporated by a laser.
Claim 15
Independent Claim
73 words
A method for producing an identification document, comprising: providing a plurality of sheets including at least one data sheet comprising at least two layers; providing an information area on the data sheet; connecting the two layers into an inseparable laminate in the information area; providing a seam area in the at least one data sheet in which the layers are not connected; and binding the sheets into a book at the seam area.
Claim 16
Independent Claim
73 words
A method for producing an identification document, comprising: providing a plurality of sheets including at least one data sheet comprising at least two layers; providing an information area on the data sheet; connecting the two layers into an inseparable laminate in the information area; providing a seam area in the at least one data sheet in which the layers are not connected; and binding the sheets into a book at the seam area.
Claim 17
Dependent Claim
25 words
The method of claim 14, wherein the step of connecting the two layers into an inseparable laminate comprises laminating the layers under heat and pressure.
Claim 18
Dependent Claim
47 words
The method of claim 15, wherein the layers comprise plastic foils and the step of providing a plurality of sheets further comprises providing a separation layer between the plastic foils in the seam area to prevent the connection of the layers in the seam area during lamination.
Claim 19
Dependent Claim
30 words
The method of claim 16, wherein the step of providing the separation layer between the plastic foils in the seam area comprises applying the separation layer by a printing process.
Claim 20
Dependent Claim
28 words
The method of claim 14, further comprises subjecting the data sheet to additional measures in the seam area to prevent the identification document from easily unfolding by itself.

The method of claim 18, wherein the step of subjecting the data sheet to additional measures comprises deforming the data sheet in the seam area by heat action such that the layers of the data sheet cling to the other sheets that are bound to the identification document.
Claim 22
Dependent Claim
48 words
The method of claim 18, further comprising deforming the data sheet thermoplastically before the step of binding the sheets into a book such that during the binding step the data sheet clings in the seam area to the other sheets that are also bound in the seam area.
Claim 23
Dependent Claim
52 words
The method of claim 18, wherein the data sheet has a format exceeding the document format in size such that the layers of the data sheet form protrusions that protrude beyond the seam area and further comprising the step of trimming the protrusions to prevent the book from easily unfolding by itself.
