Description

The invention relates to a book-like identification document, in particular a passport booklet, with a plastic data page and a paper page following or preceding the plastic data page. The invention also relates to a production method for such an identification document.

Passports and other book-like identification documents often have the form of a small booklet with an outer cover, a bundle of paper made up of several pages of content and a data page made of plastic, which is usually provided with high-quality personalization features and integrated security elements.

Proceeding from this, the invention is based on the object of providing a book-like identification document of the type mentioned at the beginning with increased security against forgery.

This object is achieved by the features of the independent claims. Developments of the invention are the subject of the dependent claims.

• - die Kunststoffdatenseite einen transparenten Fensterbereich aufweist, in den eine Fensterinformation eingebracht ist,
• - die genannte Papierseite zumindest in einem in geschlossenem Zustand des Identifikationsdokuments an den Fensterbereich der Kunststoffdatenseite angrenzenden Merkmalsbereich mit Kaolin versetzt ist, und
• - in diesen Merkmalsbereich eine mit der Fensterinformation übereinstimmende und deckungsgleiche Papierinformation eingebracht ist.

According to the invention it is provided in a generic identification document that

• - the plastic data page has a transparent window area in which window information is introduced,
• - said paper side is offset with kaolin at least in a feature area adjoining the window area of the plastic data page in the closed state of the identification document, and
• - Paper information that matches and is congruent with the window information is introduced into this feature area.

In the invention, the paper information of the paper page forms a type of shadow information for the window information present in the data page. The congruent arrangement of the two corresponding pieces of information in successive pages which differ in terms of material technology provides additional authentication of the identification document, which makes it much more difficult to reproduce the document.

In the closed state of the identification document, the plastic data side and the paper side lie directly on top of one another. The area of the paper page then lying directly above or below the window area defines the mentioned feature area of the paper page.

The window information and the paper information each represent a laser marking with particular advantage. It was surprisingly found that the offset of the paper side with kaolin allows congruent laser marking to be introduced into the window area of the plastic data side and the marking area of the paper side at the same time. Without such a kaolin addition, an adjacent paper side is not changed by the laser processes when processing the plastic data side.

In an advantageous embodiment, said paper side has a layer structure with a paper core and a surface layer which is arranged on the side of the paper core facing the plastic data side. The surface layer is mixed with kaolin, at least in the feature area. In addition to kaolin, the surface layer of the paper side expediently also contains titanium dioxide pigments and / or aluminum hydroxide.

In addition, the surface layer expediently contains binders, for example natural or synthetic polymers such as starch, polyvinyl alcohols, styrene acylates and / or polyvinyl acetates.

Alternatively, the kaolin can be provided not only in a surface layer, but in the volume of the paper side. In all cases, kaolin is added to the paper side at least in the feature area, it being possible both to provide kaolin only in the feature area and to add kaolin to the entire paper side.

The kaolin portion in the feature area of the paper side, in particular the kaolin portion in the feature area of the surface layer of the paper side, is advantageously between 1% and 10%. The proportion of kaolin can be determined, for example, as the proportion of ash (loss on ignition according to ISO 2144).

The data page is advantageously formed by a polycarbonate layer or contains one or more polycarbonate layers.

The window area can basically have any shape. For example, the window area can be designed in a rectangular manner in the interior of the data page, or it can be designed in the form of a longitudinal or transverse strip extending over the entire data page.

The window information and the paper information can represent a picture motif, in particular a portrait, a logo or a coding such as a barcode or an alphanumeric character string. Specifically, the window information and the paper information can include an access number of the identification document, the name of the Represent the document owner or the signature of the document owner.

In an advantageous embodiment, the paper information can form hidden information on the paper side. For example, a suitable background print on the paper side can ensure that the paper information that is congruent with the window information is not always visible, but only appears from special viewing directions or only when aids are used. The security of authenticity is thereby further strengthened, since the presence of the paper information corresponding to the window information cannot be easily recognized by a potential forger.

In relation to the reading direction of the identification document, the paper page can be both the paper page following the plastic data page and the paper page preceding the plastic data page. If the paper side shows the side following the plastic data side, the paper information appears when the paper side is viewed separately on its front side, the correct way round to the window information. In the case of a previous page, however, the paper information appears on the reverse side of the paper page, mirror-inverted to the window information.

The invention also includes a method for producing a book-like identification document of the type described, in which method the window information in the transparent window area and the paper information in said paper page are generated at the same time by applying a laser to the window area of the plastic data page.

To generate the window information and the paper information, a laser beam, for example a pulsed laser beam, can be guided over the surface of the window area in the pattern of the desired information. Alternatively, a large-area laser beam can be used together with a suitable mask with advantage.

Since the laser application always takes place through the window area into the adjacent paper side, when the paper information is inserted into the paper page following in the identification document, the front side is displayed in the correct way, and when the paper side is inserted into the previous paper side in the identification document, the reverse side is displayed. The latter variant can be used to advantage in particular with hidden paper information.

Further exemplary embodiments as well as advantages of the invention are explained below with reference to the figures, in the representation of which a representation true to scale and proportion was dispensed with in order to increase the clarity.

• 1 in perspektivischer Ansicht schematisch ein erfindungsgemäßes Passbüchlein mit mehreren Papierseiten und einer Kunststoffdatenseite, und
• 2 schematisch einen Querschnitt des Passbüchleins der 1 im Fensterbereich der Kunststoffdatenseite beim Schritt der Laserbeaufschlagung, wobei (a) den Zustand vor und (b) den Zustand nach der Laserbeaufschlagung zeigt.

Show it:

• 1 in a perspective view schematically a passport booklet according to the invention with several paper pages and a plastic data page, and
• 2 schematically a cross section of the passport booklet of 1 in the window area of the plastic data page in the step of laser exposure, where (a) shows the state before and (b) shows the state after laser exposure.

The invention will now be explained using the example of a passport booklet. 1 shows a schematic perspective view of a passport booklet according to the invention 10 that comes in an envelope cover 16 several pages of paper 12th , 14th and a plastic data page 20th contains.

The plastic data page 20th des Büchlein has, in addition to other personalization and security features, a transparent window area 22nd in which a window information 24 is introduced, which is represented in the exemplary embodiment for illustration by the number sequence “33550336”. With the window information 24 it can be, for example, an access number (CAN), the name of the passport holder or their signature.

The one in the reading direction of the plastic data page 20th next page in the passport booklet 10 represents a paper page 12th represents, in the case of a feature area 32 a paper information 34 is introduced. The paper information 34 agrees with the window information 24 corresponds, so represents the same sequence of digits. In addition, the paper information 34 and the window information 24 arranged congruently to one another, so that when passport book pages 20th , 12th are exactly on top of each other in register.

This congruent arrangement of the two pieces of information with the same content 24 , 34 in different passport book pages 20th , 12th becomes an additional authentication of the passport booklet 10 achieved.

In order to be able to produce a passport booklet with this additional protection, the paper side 12th be designed in a special way and also in the production of the booklet at the same time with the plastic data page 20th and through their window areas 22nd be subjected to laser radiation therethrough, as shown below with reference to the illustration of 2 explained in more detail.

2 shows schematically a cross section of the passport booklet 10 in the window area 22nd the plastic data page 20th at the step of laser exposure. The plastic data page 20th and the following side of the paper 12th are shown with a small distance for the sake of clarity, but in practice lie directly on top of one another when the laser is applied.

With reference first to 2 (a) is the plastic data page 20th of the passport book 10 formed for example from polycarbonate and generally contains several personalization and security features that are not essential for the present invention and are therefore not shown in the figure. The plastic data page 20th has a transparent window area 22nd on, which is rectangular in the embodiment and arranged inside the data page.

The ones on the plastic data page 20th next page of the passport booklet 10 represents a paper page 12th represents a layer structure of a paper core 36 and one of the data pages 20th has facing surface layer 38. The surface layer 38 contains a mixture of titanium dioxide and aluminum hydroxide and, as a special feature, the filler kaolin in a proportion of, for example, 5%.

The plastic data page 20th is together with the underlying paper side 12th in the window area 22nd with laser radiation 40 applied to the desired window information 24 in the window area 22nd to register ( 2 (a) ). A pulsed laser beam, for example, can be used for this purpose 40 in the pattern of the desired window information over the area of the window area 22nd be guided.

The inventor has now surprisingly found that the surface layer 38 is laser-sensitized by the addition of kaolin to such an extent that the laser exposure 40 not only for generating the window information 24 in the pane of the data page 20th , but also to a blackening in the adjacent surface layer 38 of the paper side 12th and thus for generating the paper information 34 leads.

As the plastic data page 20th and the paper side 12th are directly on top of each other when the laser is applied, the information 24 , 34 simultaneously in both passport book pages 20th , 12th with identical information content and congruent to one another, as in 2 B) shown. The paper information 34 forms in the finished passport booklet 10 thus a kind of shadow information of the window information 24 , as mentioned in connection with 1 shown and described.

Should the paper information 34 The paper side can form hidden information 12th in the labeling area, for example, can be provided with a camouflaging background layer that hides the presence of the paper information under normal viewing conditions. For example, the background layer can be made black, but with a different gloss behavior than the laser-marked paper information 34 show so that it is only visible when the light is grazing.
