Description

Datenseite für ein buchartiges Dokument sowie Verfahren Data page for a book-type document and procedures
zur Herstellung einer solchen Datenseitefor producing such a data page

The invention relates to a data page, in particular a Personalisierdatenseite, for a book-like document and a method for producing such a data page.

From WO 2006/079224 A1 a data page for a passport is known. This data page has a flexible layer to form a tab which is integrated between two data carriers. The disks form a front page booklet and a back page booklet. The flexible layer is connected to the two data carriers by lamination, welding or gluing, the flexible layer only partially protruding between the data carriers and furthermore a middle layer being provided between the data carriers. The layers of the data carrier can be made of polycarbonate. By gluing, welding or laminating, a permanent connection of the data carrier with the flexible fabric can be produced.

From DE 10 2009 051 106 A1 a data page for a book-type document is known which comprises a front page booklet and a back page booklet. In between lying a middle layer or a middle layer is provided, which is connected in each case with the interposition of a leveling layer with the front page booklet and back cover. In the middle layer, an opening is provided to guide a flexible hinge for a loop-shaped configuration of a tab. The same is evident from EP 2 116 390 A2.

From DE 10 2007 036 838 A1 a data page for a book-type document is known, in which a front page booklet is connected to a back side booklet with the interposition of a middle layer which protrudes from the front side booklet and the back booklet to form a tab. Between the middle layer and a layer of the front-side booklet or back-side book lying thereon, a non-destructively detachable connection is formed at an interface by an energy input by means of a laser into the interface.

The invention has for its object to provide a data page, which meets the increased requirements of a permanent connection between a front page booklet and a back cover with the involvement of a flexible tab.

This object is achieved by a data page, in which between a layer or a printing layer of a front booklet and between a layer or printing layer of a back cover a tab made of a flexible layer and at least one leveling layer is provided, wherein the at least one compensation layer comprises a glass transition temperature, the is lower than the glass transition temperature of the adjacent layers or printing layers of the front page booklet or back side booklet. This results in the lamination of the front and back side booklet incorporating the tab and the leveling layer a faster softening of the leveling layer, whereby an improved adhesive bond is given to the adjoining layers or pressure layers and the tab.

Preferably, at least the adjacent layers or pressure layers or both and the at least one leveling layer are made of the same polymer, but differ in glass transition temperature from one another such that the glass transition temperature of the leveling layer is lower than that of the adjacent layer or pressure layer.

A further preferred embodiment of the invention provides that the glass transition temperature T _{g of} the at least one leveling layer is lower by 10 ° C., preferably by 15 ° C., more preferably by 20 ° C., compared to the adjacent layer or pressure layer of the front and back side folders ,

The tab is preferably designed as a flexible fabric, in particular as a fabric tape. This has the advantage that during laminating, the adjacent layers or pressure layers of the front side booklet, the back side book and the leveling layer can penetrate at least partially into the fabric structure, thereby providing an improved connection due to the forming entanglement between the web and the layers or print layers achieve.

It is preferably provided that the compensating foil consists of polycarbonate or polyethylene terephthalate and in particular has a glass transition temperature of less than 148.degree. As a result, a permanent, reinforced and permanent connection between the front and back pages by means of the compensating layer can be made possible.

A further preferred embodiment of the data page provides that the thickness of the at least one compensating layer is smaller than the thickness of the tab. As a result, when laminating the individual superimposed layers of the front and back pages, a reinforced pressing of the tab in the adjoining layer or pressure layer of the front or back side booklet is achieved in order to achieve an increased connection of the front and back side booklet with the tab. For example, the leveling layer has a layer thickness of approximately 100 μm and the tab formed from the flexible fabric has a layer thickness of approximately 130 μm to 160 μm.

The tab is preferably prefixed with the projecting portion on a printing layer or on a layer applied to the printing layer layer of the front or back side booklet. As a result, a simplified handling in the merging of the front and back side booklet can be made possible to a layer composite, which is then preferably laminated under the action of heat and / or pressure to a laminate composite.

The front side booklet, which may also be referred to as a data page booklet, comprises at least one printing layer which is in particular opaque and at least one layer which is in particular transparent, which is applied on the outside of the printing layer. Advantageously, a printed layer for a security feature, in particular a see-through feature, is provided on the printing layer, especially opposite the outer side. In this case, a screen printing ink is advantageously used, which is known for example from EP 0 688 839. This screen printing ink leads in particular when using the printing layer made of polycarbonate to a monolithic structure, so that the printing layer is not a release layer that would allow easier release of the layers.

The back side booklet, which may also be referred to as title page booklet, comprises at least one printing layer, which is preferably opaque and at least on its outside a layer which is preferably transparent.

Depending on the applications, the front and back pages can have a plurality of layers lying on top of one another, in particular also transparent layers, on or in which security features are applied or incorporated.

A preferred embodiment provides that the front or back side pocket at least accommodates a transponder module with an IC chip and an antenna, which are preferably covered by a further layer. In this case, such an antenna can be applied by means of a screen printing process, in particular with a silver conductive paste.

Preferably, the transponder module applied to the printing layer is protected by a further layer applied thereto and is preferably fixed at least in sections by means of heat and / or ultrasound. Thus, by merging the printing layer with the transponder module applied thereon, secure handling for the production of a front and back side booklet can be made possible or a reliable feeding of the individual layers to a layer composite in order to laminate a data page.

Preferably, the layers or printing layers of the front and back pages are made of polycarbonate, so that a PC data page is formed, which comprises a flexible flap of a fabric. Likewise, polyethylene terephthalate can be used.

The object underlying the invention is further achieved by a method in which a layer composite consisting of a front and a back side booklet and lying therebetween is laminated from at least one leveling layer and a tab under the action of heat to a laminate composite, wherein a leveling layer used is formed whose glass transition temperature is less than the glass transition temperature of the adjoining the compensating layer layers or pressure layers of the front or back side booklet. As a result, a reinforced adhesive bond between the front and back side booklet can be done with the involvement of the tab.

An advantageous embodiment of the method provides that the tab is at least partially fixed with a projecting into the data page before merging the front and back side booklet to a layer composite with the layer or the printing layer of the front or back side booklet by heat or ultrasound. The tab can be connected by individual stapling points by means of ultrasonic welding, by lamination or gluing as well as by a sheet-like welding to the front or back side booklet.

Further, the tab is positioned to the front or back side booklet so that the protruding portion and the protruding portion are the same width.

Furthermore, in order to improve the adhesive bond between the front and back pages and the tab, the compensating layer is positioned with its front side in abutment against the opposite end side of the tab. As a result, the tab can be integrated into the data page on three sides with adjacent layers and fixed.

The invention and further advantageous embodiments and developments thereof are described in more detail below with reference to the examples shown in the drawings and explained. The features to be taken from the description and the drawings can be applied individually according to the invention individually or in combination in any combination. Show it:

FIG. 1 shows a book-like document 11 in perspective. This book-type document 11 is, for example, an identification document, such as a passport or an identity card. The document 11 includes, for example, a book cover 12. On an inner side of the book cover 12, a header 14 may be provided, which is attached to the book cover 12. Via a common seam 16, a data page 17 and, for example, one or more inner sides 18 are preferably connected to at least the attachment 14, if this is present. Alternatively to the seam, a weld or other types of connection can be selected. The insides 18 of the book-like document 11 are used to hold visas, stamps or other entries. By way of example, the data page 17 may be designed in accordance with the ICAO standard and may include a document holder image 19, an OCR-readable ICAO zone 21 and other personalization data 22. The Personalisierdaten 22 are provided within the data page 17. The data page 17 has a tab 23, which extends over the seam 16, for example. This tab 23 also includes a seam area in which the seam 16 is formed. Alternatively, instead of the seam 16 or in addition to the seam 16, an adhesive and / or welded connection may also be provided in order to integrate the data page 17 with the tab 23 into the book-type document 11.

FIG. 2 schematically shows a view of the data page 17. The data page 17 is equipped, for example, with a transponder module 24, which consists of an IC chip 25 and an antenna 26. In addition, further electronic and / or other security elements, in particular diffractive security elements, can be incorporated.

The data page 17 comprises a front page booklet 28 and a back side booklet 29, between which the tab 23 and at least one compensation layer 31 are arranged. The front page booklet 28, which can also be referred to as a data page booklet, comprises at least one printing layer 33 and at least one

further layer

35, 36, 37. The printing layer 33 is opaque, wherein the at least one

layer

35, 36, 37 is advantageously made transparent. In the present embodiment, an outer protective layer 35 is present, which has, for example, a layer thickness of 50 microns. This protective layer 35 is connected to a second layer 36, wherein preferably between the protective layer 35 and the second layer 36, a printed image 34 is advantageously provided for a data page including a security print. The second layer 36 comprises, for example, a layer thickness of 100 μm. Advantageously, this protective layer 35 and the second layer 36 are not made laser-capable. In the protective layer 35, for example, a security feature 38, such as a CLI feature (Changeable Laser Image) or an MLI feature (Multiple Laser Image) may be introduced.

A third layer 37, which is likewise transparent, is connected to its second layer 36 and receives the pressure layer 33. On an inner side of the pressure layer 33, a see-through feature can be applied by means of a screen printing. Such a printed layer 39 does not constitute a separating layer, but in particular forms a monolithic structure in the formation of the printing layer 33 made of polycarbonate. A further layer 41, which is advantageously transparent and, in particular, in the form of a non-laserable layer, is applied to this printing layer 33 or to the printed layer optionally applied thereon. This layer 41 has, for example, a layer thickness of 100 .mu.m in analogy to the printing layer 33, which may include, for example, a layer of 100 microns. This results in this embodiment, a front page book 28 with a total thickness of, for example, 400 microns.

The back side booklet 29 may be formed deviating from the front page booklet 28 and consists for example of a protective layer 43, which is applied to a second layer 44. In between, a printed layer 48 may be applied for, for example, a title page. The printed layer 48 may, for example, contain an optically variable color (OVF), in particular an OVI (Optically Variable Ink, for example from Sicpa). Both layers 43, 44 are preferably formed as laserable layers and in particular transparent.

The second layer 44 receives, for example, a pressure layer 45, which is opaque. On this pressure layer 45, the transponder module 24 is preferably provided. The pressure layer 45 is provided after application with a further cover layer 47, which is preferably pre-fixed with the pressure layer 45, so that it forms a Zwischenlagenverbund. The printing layer 45, the second layer 44 and the cover layer 47 may have a layer thickness of 100 μm, for example. The protective layer may be, for example, a thickness of 50 microns. In particular, the cover layer may be formed as a non-laserable layer.

In such a structure, the back side booklet 29 may have a thickness of 350 μm, for example.

The tab 23 is a fabric bag or made of a flexible fabric. Preferably, a polymer material is provided. The fabric pocket has a region 49 projecting beyond the front or back

side pocket

28, 29 and an area 50 projecting into it. Preferably, the tab 23 is provided such that an equal division is given with respect to the projecting and outwardly projecting area. The tab 23 made of the flexible fabric has, for example, a thickness of 130 .mu.m to 160 .mu.m, whereas the compensating layer 31 or compensating layers arranged between the front and

rear side folders

28, 29 have a thickness which is smaller than the thickness of the fabric tab.

The layers as well as the printing layers of the front and

back pages

28, 29 are advantageously all made of polycarbonate or polyethylene terephthalate. Preferably, one of the polymers is bisphenol A polycarbonate or a block copolymer containing bisphenol A polycarbonate and at least one other polycarbonate. In particular, polymers are used in which the properties such as glass transition temperature can be adjusted via the chain length and the degree of crosslinking. Likewise, the leveling layer 31, which has a glass transition temperature which is less than that of the at least adjacent to the leveling layer 31 layers or pressure layers of the front and back side booklet 28, 29th

The number of individual layers and / or printing layers for forming the front page booklet 28 and back page booklet 29 may be selected and varied application specific. The arrangements in Figures 3 and 4 are exemplary only.

The data page 17 can be made as follows: The front page 28 and back page 29 are made separately. For example, in the front-side booklet 28, the printing layer 33 is provided with the printed layer 39 before the

further layers

35, 36, 37, and 41 are carried together according to the predetermined order to subsequently arrange the individual layers in a laminate. Preferably, prior to the merging of the

layers

35, 36, 37, 41 to the printing layer 33, the tab 23 is prefixed or stapled to the layer 39 by heat or ultrasound.

To form the backsheet 29, the transponder module 24 is first applied to the printing layer 45, and then the cover layer 47 is at least prefixed or stapled by heat and / or ultrasound to the printing layer 45. This interlayer composite is combined with the

other layers

43, 44 to form the back side booklet together. These can also be prefixed or stapled to one another by heat and / or ultrasound, in order to facilitate the merging of the front side booklet 28, the at least one leveling layer 31 and the back side booklet 29 to form a laminate, which is then laminated under heat to form a laminated composite as a data page 17 ,

FIG. 4 shows an alternative embodiment of a layer structure of the data page 17 with respect to FIG. This embodiment deviates from FIG. 3 in that, for example, the layer 41 of the front side booklet 28 is not provided, so that a thinned structure of a data page 17 with an inserted tab 23 is thereby made possible. As a result, the front side booklet 28 can have a total thickness of 300 μm, so that the data page 17 can be reduced with respect to the embodiment in FIG. 3 with a layer thickness of 850 μm to 750 μm. The above figures for the layer thicknesses are only examples. After lamination, the layer thickness is usually reduced by about 15 μm.

All of the aforementioned features are essential to the invention and can be combined with one another as desired.
