## Abstract

An inlay sheet for a book-like identification document. The inlet sheet may include a first hinge layer comprising polycarbonate and a second hinge layer comprising a flexible material different to polycarbonate, e.g. PET, polyurethane, fabric, mesh. The second hinge layer is attached to the first hinge layer. A first datapage layer and a second datapage layer are attached to the first hinge layer and the second hinge layer, respectively, such that the first and second hinge layers are positioned between the first and second datapage layers for forming a datapage section haying a datapage thickness. The first and second datapage layers form a common datapage inner front edge and the first and second hinge layers extend beyond the common datapage inner front edge such that a hinge section is formed having a hinge thickness smaller than the datapage thickness.

## Claims

### Claim at position 1

1-16. (canceled)

### Claim 17

An inlay sheet configured to be used in a book-like identification document, the inlay sheet comprising:
a first hinge layer comprising polycarbonate;
a second hinge layer comprising a flexible material different to polycarbonate, the second hinge layer being attached to the first hinge layer;
a first datapage layer; and
a second datapage layer;
wherein the first datapage layer and the second datapage layer are attached to the first hinge layer and the second hinge layer, such that the first and second hinge layers are positioned between the first and second datapage layers forming a datapage section having a datapage thickness (tdp), the first and second datapage layers forming a datapage inner front edge;
wherein the first and second hinge layers extend beyond the datapage inner front edge such that a hinge section is formed having a hinge thickness (th) smaller than the datapage thickness (tdp).

### Claim 18 (depends on 17)

The inlay sheet of claim 17, further comprising a third hinge layer comprising polycarbonate, the second hinge layer being positioned between and attached to the first and third hinge layers.

### Claim 19 (depends on 18)

The inlay sheet of claim 18, further comprising a common front edge for the hinge layers formed by at least one of a polycarbonate strip or a strip formed during lamination of the hinge layers made of polycarbonate by at least one of pressing or squeezing.

### Claim 20 (depends on 17)

The inlay sheet of claim 17, wherein at least a component of an RFID element is positioned in the second hinge layer.

### Claim 21 (depends on 20)

The inlay sheet of claim 20, wherein the component extends at least in part n the datapage section.

### Claim 22 (depends on 18)

The inlay sheet of claim 18, wherein at least one of:
the hinge thickness (th) is at least 30% smaller than h datapage thickness (tdp); or
a hinge layer thickness (thl) of at least one of the first or third hinge layers is at least 80% smaller than a datapage layer thickness (tdpl) of at least one of the first or second datapage layers.

### Claim 23 (depends on 18)

The inlay sheet of claim 18, wherein at least one of:
the datapage thickness (tdp) is smaller than 600 μm;
the hinge thickness (th) is smaller han 300 μm;
respective datapage thicknesses (tdp1, tdp2) of the first and second datapage layers are smaller than 300 μm; or
respective hinge layer thicknesses (thl) of the first and third hinge layer are smaller than 100 μm.

### Claim 24 (depends on 17)

The inlay sheet of claim 17, wherein at least one printed or laser engraved pattern is provided in the hinge section.

### Claim 25 (depends on 17)

The inlay sheet of claim 17, wherein the second hinge layer comprises polyurethane.

### Claim 26 (depends on 25)

The inlay sheet of claim 25, wherein at least one printed or laser engraved pattern is provided in the hinge section.

### Claim 27 (depends on 25)

The inlay sheet of claim 25, further comprising a third hinge layer comprising polycarbonate, the second hinge layer being positioned between and attached to the first and third hinge layers.

### Claim 28

A method for manufacturing an inlay sheet, the method comprising:
providing a first hinge layer comprising polycarbonate;
providing a second hinge layer comprising a flexible material different to polycarbonate;
providing a first datapage layer forming a part of a datapage section;
providing a second datapage layer forming another part of the datapage section; and
bonding together the first and second hinge layers and the first and second datapage layers such that the first and second hinge layers are positioned between the first and second datapage layers and the first and second hinge layers extend beyond an inner front edge of the datapage section, forming a hinge section having a hinge section thickness (th) smaller than a datapage section thickness (tdp).

### Claim 28 (depends on 28)

The method of claim 28, further comprising providing at least a component of an RFID element in the second hinge layer and positioning the component such that it extends at least partly in the datapage section.

### Claim 29 (depends on 28)

The method of claim 28, further comprising:
providing a third hinge layer comprising polycarbonate;
positioning the second hinge layer between the first and third hinge layers; and
bonding the first, second, and third hinge layers to each other.

### Claim 29 (depends on 29)

The method of claim 29, wherein at least one of:
the hinge section thickness (th) is at least 30% smaller than the datapage section thickness (tdp); or
a hinge layer thickness (thl) of at least one of the first or third hinge layers is at least 80% smaller than a datapage layer thickness (tdp1) of at least one of the first or second datapage layers.

### Claim 30 (depends on 29)
