Dabei können diese Dokumente nur ein erfindungsgemäßes Datenblatt oder mehrere solcher Datenblätter enthalten, welche in der Regel (aber nicht zwingend) zwischen zwei Buchdeckeln (hart oder flexibel) angeordnet sind. Zusammen mit dem Datenblatt können auch hiervon verschiedene weitere Datenblätter, beispielsweise auf Basis von Papierwerkstoffen, enthalten sein. Ein solches Dokument ist beispielsweise ein Reisepass, es sind aber auch beliebige andere Dokumente dieses Aufbaus umfasst.Background of the Invention and Related Art Datasheets of the invention are typically included in book-type documents. In the context of the invention, the term "book form" also includes booklets, the pages or sheet number can be in the range of 1 to 50, typically from 5 to 40, lie. These documents can contain only a data sheet according to the invention or several such data sheets, which are usually (but not necessarily) arranged between two book covers (hard or flexible). Together with the data sheet can also from this various other data sheets, for example based on paper materials. Such a document is, for example, a passport, but it also includes any other documents of this structure.

Solche Datenblätter tragen typischerweise Informationen, zumindest teilweise individualisiert und/oder personalisiert. Individualisiert bedeutet, auf ein Dokument bezogen, z.B. eine Seriennummer. Personalisiert bedeutet, auf den Dokumenteninhaber bezogen, z.B. Namen oder Bild. Des Weiteren können in einem solchen Datenblatt Sicherheitsmerkmale integriert sein. Dafür kommen alle fachüblichen Sicherheitsmerkmale in Frage, welche typischerweise bei Kunststofflaminaten als Datenblatt einsetzbar sind.Such data sheets typically carry information, at least partially individualized and / or personalized. Individualized means related to a document, e.g. a serial number. Personalized means referring to the document holder, e.g. Name or picture. Furthermore, security features can be integrated in such a data sheet. For all standard safety features come into question, which are typically used in plastic laminates as a data sheet.

Ein solches buchförmiges Dokument mit der Nutzung eines textilen Gewebes als Lasche bzw. Scharnier ist bekannt aus der Literaturstelle WO2006/079224 . Ein heftförmiges Dokument mit textiler Kernschicht, aber mit aufwendiger thermoplastischer Kunststoffschicht ist aus der Literaturstelle EP 1812244 bekannt. Ein Reisepass mit plastifizierter Datenseite und Verwendung eines Vliesstreifens als Knick/Klappkante ist aus der Literaturstelle EP 2116390 bekannt. Datenblätter mit textilen Kernschichten sind schließlich auch aus den Literaturstellen WO 2006/053738 A2 und EP 1 812 244 B1 bekannt.Such a book-shaped document with the use of a textile fabric as a flap or hinge is known from the literature WO2006 / 079224 , A stapled document with textile core layer, but with elaborate thermoplastic layer is from the literature EP 1812244 known. A passport with plasticized data page and use of a non-woven strip as a kink / folding edge is from the literature EP 2116390 known. Finally, data sheets with textile core layers are also from the literature WO 2006/053738 A2 and EP 1 812 244 B1 known.

Beispielsweise aus der Literaturstelle EP 0688839 A2 sind aus anderen Zusammenhängen Polycarbonate auf Basis eines geminal disubstituierten Dihydroxy-diphenylcycloalkans per se bekannt. In diesem Stand der Technik werden solche Polycarbonate als Bindemittel von Siebdruckfarben eingesetzt. Dieser Literaturstelle sind auch Verfahren zur Herstellung solcher Polycarbonate entnehmbar. Solche Polycarbonate finden mittlerweile auch im Bereich der Sicherheits- und/oder Wertdokumente Anwendung, wozu beispielhaft auf die Literaturstelle mit der PCT-Anmeldenummer PCT/DE 2007/001751 verwiesen wird.For example, from the literature EP 0688839 A2 are from other contexts based on a polycarbonate geminally disubstituted dihydroxy-diphenylcycloalkans per se known. In this prior art, such polycarbonates are used as binders of screen printing inks. This reference also discloses methods of making such polycarbonates. Such polycarbonates are now also used in the field of security and / or value documents, including, for example, the reference with the PCT application number PCT / DE 2007/001751 is referenced.

Nachteilig bei den insofern bekannten Sicherheits-und/oder Wertdokumenten ist eine unzureichende Flexibilität der Lasche des Datenblattes, was ein "Aufsperren" des Buches zur Folge hat. Des Weiteren ist z.B. bei TPU-Laschen eine potentielle Delaminationsmöglichkeit der Passkarte zwischen TPU-Innenlage und PC Außenlagen vorhanden, die nur durch zusätzlichen Aufwand, beispielsweise Beschichtungen oder Materialmodifizierung, vermindert werden kann. Bei Gewebelaschenkonzepten zur Herstellung von Sicherheits-und/oder Wertdokumenten wird typischerweise ein passkarten- bzw- datenblattfremdes Gewebematerial, z. B. Polyester verwendet. Um eine innige Verbindung von Laschenmaterial und Polymerlagen des Datenblattes zu erreichen, müssen aufwendige Durchbrüche eingebracht werden, wie sie beispielsweise in der Literaturstelle WO 2006079224 beschrieben sind.A disadvantage of the known security and / or value documents is an insufficient flexibility of the tab of the data sheet, which has a "unlocking" the book result. Furthermore, in the case of TPU tabs, for example, there is a potential delamination possibility of the passcard between TPU inner layer and PC outer layers, which can only be reduced by additional expenditure, for example coatings or material modification. In tissue bag concepts for the production of security and / or value documents, a passcard or data sheet foreign tissue material, for. B. polyester used. To achieve an intimate connection of tab material and polymer layers of the data sheet, elaborate breakthroughs must be introduced, as for example in the reference WO 2006079224 are described.

Aus der WO 2007/034129 sind ein buchartiges Dokument und ein Verfahren zu dessen Herstellung bekannt. Dieses buchartige Dokument umfasst ein Datenblatt, welches aus einem mehrschichtigen Laminat gebildet ist, wobei zwischen den Laminatschichten ein Mikrochip eingebracht ist. Auf diese laminierten Komponenten, die als Inlay bezeichnet werden, wird ein Bogen aufgebracht. Dieser Bogen ist doppelseitig und bildet daher keine Lasche. Vielmehr ist die Lasche durch die äußere Laminatschichten ausgebildet.From the WO 2007/034129 A book-type document and a method for its production are known. This book-type document comprises a data sheet which is formed from a multilayer laminate, wherein a microchip is inserted between the laminate layers. On these laminated components, which are referred to as inlay, an arc is applied. This bow is double-sided and therefore does not form a flap. Rather, the tab is formed by the outer laminate layers.

Technisches Problem der ErfindungTechnical problem of the invention

Der Erfindung liegt daher das technische Problem zu Grunde, ein Datenblatt anzugeben, welches einerseits eine Lasche mit hoher Flexibilität aufweist und so ein "Aufsperren" des Dokumentes sicher vermeidet, und andererseits eine sichere Verbindung aller Komponenten des Datenblattes, einschließlich der Lasche, miteinander bei einfacher Herstellbarkeit zu gewährleisten.The invention is therefore based on the technical problem of specifying a data sheet, which on the one hand has a flap with high flexibility and so safely avoids "unlocking" the document, and on the other hand a secure connection of all components of the data sheet, including the tab, with each other easier To ensure manufacturability.

Suitable compounds are, for example, phenol, tert-butylphenols or other alkyl-substituted phenols. For controlling the molecular weight, in particular small amounts of phenols of the formula (Ic) are suitable

 wherein
R is a branched C 8 - and / or C 9 -alkyl radical.

Bevorzugt ist im Alkylrest R der Anteil an CH3-Protonen zwischen 47 und 89 % und der Anteil der CH- und CH2-Protonen zwischen 53 und 11 %; ebenfalls bevorzugt ist R in o- und/oder p-Stellung zur OH-Gruppe, und besonders bevorzugt die obere Grenze des ortho-Anteils 20 %. Die Kettenabbrecher werden im allgemeinen in Mengen von 0,5 bis 10, bevorzugt 1,5 bis 8 Mol-%, bezogen auf eingesetzte Diphenole, eingesetzt.Preferably, in the alkyl radical R, the proportion of CH 3 protons between 47 and 89% and the proportion of CH and CH 2 protons between 53 and 11%; also preferably R is in the o- and / or p-position to the OH group, and more preferably the upper limit of the ortho-portion is 20%. The chain terminators are generally used in amounts of 0.5 to 10, preferably 1.5 to 8 mol%, based on diphenols used.

Die Polycarbonatderivate können vorzugsweise nach dem Phasengrenzflächenverhalten (vgl. H. Schnell "Chemistry and Physics of Polycarbonates", Polymer Reviews, Vol. IX, Seite 33ff., Interscience Publ. 1964 ) in an sich bekannter Weise hergestellt werden.The polycarbonate derivatives may preferably be prepared according to the interfacial behavior (cf. H. Schnell "Chemistry and Physics of Polycarbonates ", Polymer Reviews, Vol. IX, p. 33ff., Interscience Publ. 1964 ) are prepared in a conventional manner.

Hierbei werden die Diphenole der Formel (Ia) in wässrig alkalischer Phase gelöst. Zur Herstellung von Copolycarbonaten mit anderen Diphenolen werden Gemische von Diphenolen der Formel (Ia) und den anderen Diphenolen, beispielsweise denen der Formel (Ib), eingesetzt. Zur Regulierung des Molekulargewichts können Kettenabbrecher z.B. der Formel (Ic) zugegeben werden. Dann wird in Gegenwart einer inerten, vorzugsweise Polycarbonat lösenden, organischen Phase mit Phosgen nach der Methode der Phasengrenzflächenkondensation umgesetzt. Die Reaktionstemperatur liegt zwischen 0°C und 40°C.In this case, the diphenols of the formula (Ia) are dissolved in an aqueous alkaline phase. For the preparation of copolycarbonates with other diphenols, mixtures of diphenols of the formula (Ia) and the other diphenols, for example those of the formula (Ib), are used. For the regulation of the molecular weight, chain terminators e.g. of the formula (Ic) are added. Then, in the presence of an inert, preferably polycarbonate-dissolving, organic phase is reacted with phosgene by the method of interfacial condensation. The reaction temperature is between 0 ° C and 40 ° C.

Die gegebenenfalls mitverwendeten Verzweiger (bevorzugt 0,05 bis 2,0 Mol-%) können entweder mit den Diphenolen in der wässrig alkalischen Phase vorgelegt werden oder in dem organischen Lösungsmittel gelöst vor Phosgenierung zugegeben werden. Neben den Diphenolen der Formel (Ia) und gegebenenfalls anderen Diphenolen (Ib) können auch deren Mono- und/oder Bis-chlorkohlensäureester mitverwendet werden, wobei diese in organischen Lösungsmitteln gelöst zugegeben werden. Die Menge an Kettenabbrechern sowie an Verzweigern richtet sich dann nach der molaren Menge von Diphenolat-Resten entsprechend Formel (Ia) und gegebenenfalls Formel (Ib); bei Mitverwendung von Chlorkohlensäureestern kann die Phosgenmenge in bekannter Weise entsprechend reduziert werden.The optionally used branching agents (preferably 0.05 to 2.0 mol%) can either be initially charged with the diphenols in the aqueous alkaline phase or added in the organic solvent before phosgenation. In addition to the diphenols of the formula (Ia) and, if appropriate, other diphenols (Ib), their mono- and / or bis-chlorocarbonic acid esters may also be used, these being added dissolved in organic solvents. The amount of chain terminators and of branching agents then depends on the molar amount of diphenolate radicals corresponding to formula (Ia) and optionally formula (Ib); When using chloroformates the amount of phosgene can be reduced accordingly in a known manner.

Geeignete organische Lösungsmittel für die Kettenabbrecher sowie gegebenenfalls für die Verzweiger und die Chlorkohlensäureester sind beispielsweise Methylenchlorid, Chlorbenzol, insbesondere Mischungen aus Methylenchlorid und Chlorbenzol. Gegebenenfalls können die verwendeten Kettenabbrecher und Verzweiger im gleichen Solvens gelöst werden.Suitable organic solvents for the chain terminators and optionally for the branching agents and the chloroformates are, for example, methylene chloride, chlorobenzene, in particular mixtures of methylene chloride and chlorobenzene. Optionally, the chain terminators and branching agents used can be dissolved in the same solvent.

Als organische Phase für die Phasengrenzflächenpolykondensation dienen beispielsweise Methylenchlorid, Chlorbenzol sowie Mischungen aus Methylenchlorid und Chlorbenzol.For example, methylene chloride, chlorobenzene and mixtures of methylene chloride and chlorobenzene serve as the organic phase for the interfacial polycondensation.

Als wässrige alkalische Phase dient beispielsweise NaOH-Lösung. Die Herstellung der Polycarbonatderivate nach dem Phasengrenzflächenverfahren kann in üblicher Weise durch Katalysatoren wie tertiäre Amine, insbesondere tertiäre aliphatische Amine wie Tributylamin oder Triethylamin katalysiert werden; die Katalysatoren können in Mengen von 0,05 bis 10 Mol-%, bezogen auf Mole an eingesetzten Diphenolen, eingesetzt werden. Die Katalysatoren können vor Beginn der Phosgenierung oder während oder auch nach der Phosgenierung zugesetzt werden.The aqueous alkaline phase used is, for example, NaOH solution. The preparation of the polycarbonate derivatives by the interfacial process can be catalyzed in a conventional manner by catalysts such as tertiary amines, in particular tertiary aliphatic amines such as tributylamine or triethylamine; the catalysts can be used in amounts of 0.05 to 10 mol%, based on moles of diphenols used. The catalysts can be added before the beginning of the phosgenation or during or after the phosgenation.

Die Polycarbonatderivate können nach dem bekannten Verfahren in homogener Phase, dem sogenannten "Pyridinverfahren" sowie nach dem bekannten Schmelzeumesterungsverfahren unter Verwendung von beispielsweise Diphenylcarbonat anstelle von Phosgen hergestellt werden.The polycarbonate derivatives can be prepared by the known method in the homogeneous phase, the so-called "pyridine process" and by the known melt transesterification process using, for example, diphenyl carbonate instead of phosgene.

Die Polycarbonatderivate können linear oder verzweigt sein, sie sind Homopolycarbonate oder Copolycarbonate auf Basis der Diphenole der Formel (Ia).The polycarbonate derivatives may be linear or branched, they are homopolycarbonates or copolycarbonates based on the diphenols of the formula (Ia).

Durch die beliebige Komposition mit anderen Diphenolen, insbesondere mit denen der Formel (Ib) lassen sich die Polycarbonateigenschaften in günstiger Weise variieren. In solchen Copolycarbonaten sind die Diphenole der Formel (Ia) in Mengen von 100 Mol-% bis 2 Mol-%, vorzugsweise in Mengen von 100 Mol-% bis 10 Mol-% und insbesondere in Mengen von 100 Mol-% bis 30 Mol-% und ganz besonders von 100 Mol-% bis 50 Mol-%, bezogen auf die Gesamtmenge von 100 Mol-% an Diphenoleinheiten, in Polycarbonatderivaten enthalten.By arbitrary composition with other diphenols, in particular with those of the formula (Ib), the polycarbonate properties can be varied in a favorable manner.

Hierfür kommen beispielsweise oberflächengestrichene, nicht kalandierte, saugfähige Papierwerkstoffe in Frage. Als "saugfähig" wird ein solcher Papierwerkstoff bezeichnet, dessen Wasseraufnahme nach Cobb (Cobb 60s, DIN EN 20535) oberhalb 1 g/m2, insbesondere oberhalb 10 oder 20 oder 50 g/m2 liegt. Der Cobb-Wert eines Papierwerkstoffes kann insbesondere durch Variation des Leimungsgrades des Papierwerkstoffes variiert und gezielt eingestellt werden.In a first alternative of a further development of the invention, the paper material layer (5) is substantially homogeneous and absorbent in the direction perpendicular to the main surfaces, the paper material layer (5) being saturated with the organic binder (6). For example, surface-coated, non-calendered, absorbent paper materials are suitable for this purpose. "Absorbent" refers to such a paper material whose water absorption according to Cobb (Cobb 60s, DIN EN 20535) is above 1 g / m 2 , in particular above 10 or 20 or 50 g / m 2 . The Cobb value of a paper material can be varied and specifically adjusted in particular by varying the degree of sizing of the paper material.

Die Lasche kann dabei mit Binder versehen sein oder keinen Binder aufweisen. Die Papierwerkstofflage kann nur in einem Teilbereich zwischen den Lagen angeordnet werden, oder in dem gesamten Bereich zwischen den Lagen.The invention also encompasses a method for producing a data sheet according to the invention, wherein two layers of an organic polymer material and a paper material layer are provided, wherein at least partial regions of one side of one layer or both layers and / or partial regions of one side or both sides of the paper material layer Coating of a liquid uncured binder preparation applied, in particular imprinted, wherein the layers and the paper material layer stacked to each other and arranged with mutually facing coated sides with the proviso that a part of the paper material layer as a tab outside the two layers protruding, in which case the layers and the paper material layer are laminated together, and wherein the binder is cured or crosslinked. The tab can be provided with binder or have no binder. The paper material layer can be arranged only in a partial area between the layers, or in the entire area between the layers.

Dabei ist es vorteilhaft, wenn die Laufrichtung (Orientierung der Papierfaserrichtung) der Papierwerkstofflage parallel zur Längserstreckung der Lasche orientiert ist. Dadurch wird ein gutes Aufschlag- bzw. Falzverhalten des fertigen Sicherheits- und/oder Wertdokumentes mit eingenähtem Datenblatt erreicht.It is advantageous if the direction of travel (orientation of the paper fiber direction) of the paper material layer is oriented parallel to the longitudinal extent of the tab.

Beispiel 3: Verschiedene Ausführungsformen eines erfindungsgemäßen Datenblattes und Dokumentes hiermitExample 3: Various embodiments of a data sheet according to the invention and document hereby

In den Figuren 1 und 2 ist jeweils ein erfindungsgemäßes Datenblatt 1 bzw. dessen Komponenten vor dem Laminieren dargestellt. Man erkennt in den Figuren zunächst zwei Lagen 2, 3 aus einem organischen Polymerwerkstoff, vorzugsweise aus transparentem Polykarbonat. Die Lagen 2, 3 können ihrerseits aus mehreren gestapelten Folien gebildet sein. Des Weiteren können auf oder in einer Lage 2, 3 oder beiden Lagen 2, 3 nicht gezeigte Druckschichten und/oder Sicherheitsmerkmale eingerichtet sein. Man erkennt des Weiteren in den Figuren 1 und 2 eine Papierwerkstofflage 5.In the Figures 1 and 2 in each case a data sheet 1 according to the invention or its components before lamination is shown. In the figures, two layers 2, 3 of an organic polymer material, preferably of transparent polycarbonate, are initially recognizable. The layers 2, 3 may in turn be formed from a plurality of stacked films. Furthermore, printing layers and / or security features not shown on or in a layer 2, 3 or both layers 2, 3 can be set up. One recognizes furthermore in the Figures 1 and 2 a paper material layer 5.

In der Figur 1 ist diese Papierwerkstofflage 5 aus einem saugenden Papierwerkstoff gebildet. Hierfür kommt beispielsweise Zellulose in Frage. Schließlich ist ein Binder 6 erkennbar, welcher auf die Papierwerkstofflage 5 aufgetragen wurde und diese durchtränkt. Der Binder 6 kann mittels einer Drucktechnologie auf die Papierwerkstofflage 5 aufgebracht sein, durch einseitiges oder zweiseitiges Bedrucken oder durch jede andere fachübliche Beschichtungstechnologie.In the FIG. 1 this paper material layer 5 is formed from a absorbent paper material. Cellulose is suitable for this purpose, for example. Finally, a binder 6 can be seen, which has been applied to the paper material layer 5 and impregnates it. The binder 6 may be applied by means of a printing technology to the paper material layer 5, by one-sided or two-sided printing or by any other customary coating technology.

In der Figur 2 erkennt man, dass die Papierwerkstofflage 5 aus einer Mittellage 5a gebildet ist, auf deren beiden Seiten jeweils eine Außenlage 5b, 5c angebracht ist. Die Verbindung zwischen Mittellage 5a und Außenlagen 5b und 5c kann beispielsweise durch Gautschen erfolgt sein. Als Mittellage 5a kommt beispielsweise reißfestes Baumwollpapier in Frage, während für die Außenlagen 5b und 5c Zellulosepapier verwendet werden kann. Die Mittellage sorgt dabei für Stabilität und Reißfestigkeit. Die Außenlagen 5b und 5c sorgen dagegen für die Aufnahme (Aufsaugen) des Binders 6.In the FIG. 2 recognizes that the paper material layer 5 is formed from a central position 5a, on both sides of which an outer layer 5b, 5c is attached. The connection between central layer 5a and outer layers 5b and 5c may be done by Gautschen, for example. Tear-resistant cotton paper, for example, is suitable as the middle layer 5a, while cellulose paper can be used for the outer layers 5b and 5c. The middle layer ensures stability and tear resistance. On the other hand, the outer layers 5b and 5c ensure the absorption (absorption) of the binder 6.

In beiden Figuren 1 und 2 ist ersichtlich, dass außerhalb der Lagen 2, 3 die Papierwerkstofflage 5 hervorsteht, wodurch eine Lasche 4 gebildet ist.In both Figures 1 and 2 it can be seen that outside of the layers 2, 3, the paper material layer 5 protrudes, whereby a tab 4 is formed.

Das fertige Datenblatt 1 entsteht durch Laminieren der dargestellten Komponenten in der dargestellten Anordnung bzw. Stapelung derselben. Dabei kann der Binder 6 vor dem Laminieren getrocknet sein, dies ist aber nicht zwingend notwendig. Das Laminieren erfolgt mittels einer Laminierungsvorrichtung 7, welche aus zwei Ebenen Laminierblechen 8 und 9 gebildet sein kann. Diese werden in fachüblicher Weise in einer Heiz-/ Kühlpressenkombination unter Druck beheizt und abgekühlt.The finished data sheet 1 is produced by laminating the illustrated components in the illustrated arrangement or stacking thereof. In this case, the binder 6 may be dried before laminating, but this is not absolutely necessary. The lamination takes place by means of a laminating device 7, which can be formed from two-layer laminating sheets 8 and 9. These are heated in a customary manner in a heating / cooling press combination under pressure and cooled.

Abweichend von der Darstellung der Figuren 1 und 2 kann im Bereich der Lasche 4 kein Binder vorgesehen sein. In diesem Fall erhält die Lasche 4 eine vergleichsweise höhere Flexibilität.Deviating from the presentation of Figures 1 and 2 can be provided in the region of the tab 4 no binder. In this case, the tab 4 is given a comparatively higher flexibility.

In der Figur 3 ist schließlich ein Dokument 10 gezeigt, welches ein erfindungsgemäßes Datenblatt 1 enthält. Man erkennt einen Einband 11, das erfindungsgemäße Datenblatt 1 sowie weitere Innenlagen 12. Die weiteren Innenlagen 12 können aus einem Papierwerkstoff gebildet sein oder auch aus einem synthetischen organischen Polymerwerkstoff. Ebenso sind fachübliche Verbundwerkstoffe für die weiteren Innenlagen 12 einsetzbar. Man erkennt, dass das Datenblatt 1 mit seiner Lasche 4 im Bereich einer Naht 13 zusammen mit den weiteren Innenlagen 12 in den Einband 11 eingenäht ist.In the FIG. 3 Finally, a document 10 is shown which contains a data sheet 1 according to the invention. One recognizes a cover 11, the data sheet 1 according to the invention as well as further inner layers 12. The further inner layers 12 may be formed from a paper material or from a synthetic organic polymer material. Likewise, commercially available composite materials for the further inner layers 12 can be used. It can be seen that the data sheet 1 with its flap 4 in the region of a seam 13 is sewn into the cover 11 together with the further inner layers 12.
