The object of the present invention is a multilayer film composite which has at least one layer of polycarbonate or copolycarbonate, characterized in that the polycarbonate or copolycarbonate additionally contains one or more special additives.

Obtained by extrusion of a film of polycarbonate, politicalpunch or blends of polycarbonate with complex polyesters, such as polyethylenterephtalate, polybutylenterephthalate or politological-imetadataexchange, such as film, supplied by the firm Sabic Innovative Plastic under the trade names Lexan SLX® or Xylex®, used primarily in electronics, in the domestic sphere for decorative and functional screens, as a coating film, for example, sporting goods, identification cards and blister packaging materials. Other applications of these films include the automotive industry (for example, the manufacture of body parts or exterior mirrors) or telecommunications (for example, section keys and mobile phones). These films are distinguished by high light transmission, impact resistance and heat resistance.

A special area in which the wafers used for the manufacture of films, are portable data carriers. Portable but Italy data in different versions of their design used for numerous purposes. In portable data carriers often incorporate labeling, protective signs, magnetic strip and/or an integrated circuit. Portable data carrier may have, in particular, the form of plastic cards of standard size, which can be used, for example, to perform cashless payments, confirmation of the right of access to mobile networks and so on. In addition, the known portable data carriers, which typically have a smaller thickness and larger size compared to standard plastic cards and are one of the pages of the passport.

Given the wide distribution of portable data carriers, along with associated with their production costs are increasingly playing a role in environmental security used for their manufacturing materials. This should be provided long service life of portable data carriers that applies to most of their applications. In addition, the portable data carrier in ever-increasing volume of supply labels and additional elements, and simultaneously increase the quality requirements of the respective media data.

A known technology for manufacturing high-quality portable storage media involves layering multiple polymer films. However, the reality is isemoa in accordance with such technology manufacturer of portable data carriers, which have a complex structure and consists of a large number of separate films, is quite time-consuming, and there are significant restrictions on the choice of suitable materials, which primarily relate to adjacent separate films. In addition, a separate film must possess acceptable to perform respective processes a minimum thickness. In this regard, recently there has been a trend towards the use for the manufacture of removable data received by coextruding films, which consist of several layers. In the production process such coextruding film layers are connected to each other, receiving the multilayer film material. A few received by the specified method of multilayer films can be connected with each other by layering.

This technology is known, for example, from European patent application EP-A 0640940. The speech in this application is about the production of contactless smart cards between the two coating films which is the inner film. Coating film is connected with the inner film by means of respective connecting layers. Each of the connecting layers are formed, in particular, in the form of a layer, coextruding with the appropriate coating film and/or DNAs is Rennie film. The material of the coating film and the inner film is, for example, polycarbonate. The material of the connecting layer can be modified with glycol terephthalate.

From patent application U.S. US-A 5928788 known, in particular, a multilayer data carrier, which is made by layering the inner film and the two coating films. The material of the inner film and the coating film is modified with glycol terephthalate. To prevent too strong adhesion with coating pleney with plates laminating press the outer area of these films enriched with anti-adhesion. In addition, the respective coating films consist of two coextruding layers, and anti-adhesion are present in only one of these layers.

In the international application WO 2002/41245 A2 describes a multifunctional card, which consists of several interconnected by stratifying films, at least one of which consists of at least two coextruding layers. It is envisaged, in particular, the connection of both sides of the inner film with the respective coating films. Coating film can be obtained by coextruding polycarbonate films consisting of two or three coextruder the bathrooms layers. The inner film may consist of coextruding layers of two different types. Coextrudable layers of both types are stacked in alternating sequence, and the layered structure can be formed by three or five such alternating coextrudable layers. Material coextruding layer of one type may be a polycarbonate or polyethylene terephthalate. Material coextruding layer of another type may be a thermoplastic elastomer.

In European patent application EP-A 0706152 described multilayer chip card or smart card, which consist of thermoplastic materials. Such multi-layered map, running from naslaivanija films offer significant advantages compared to the maps that are produced by time-consuming gluing, for example, by means of cyanoacrylate adhesives.

In connection with optimal mechanical properties of the polycarbonate is particularly suitable material of the above films.

The polycarbonates with additives, which are representatives of a class of tools designed to extract the products from the form described, for example, in international application WO 99/05205, as well As in patent application U.S. US-A 6008280. These polycarbonates are used, for example, as core materials for the optical data carriers, because the process of molding these polymers are characterized by the best technological properties. However, in the cited documents did not mention the use of these modified polycarbonates described above for the manufacture of cards or their suitability for lamination.

In the German patent application DE 102007004322 A1 describes a multilayer composite material, which includes at least one polycarbonate layer, optionally containing means for retrieving items from a form, such as pentaerythritoltetranitrate or glycerylmonostearate, the preferred amount is from 0.02 to 1% of the mass. Both of these compounds belong to the group proposed in the present invention supplements 1-8. Tools to extract the products from the form, as their name implies, are usually used as release agents. It is known that such tools as such primarily have the ability to prevent adhesion. Thus, the cited document does not follow that these it tools to extract the products from the form in the case of their use in higher concentrations will be able to increase the adhesion.

The production of ready-card or multi-layer composite material is carried out, in particular, with what omashu laminerade press when exposed to a pack of film pressure, ensure a tight connection of the separate films with each other. Especially preferred is the presence of at least one of the inner or coating films are extremely high ability to grip in the process of layering. This makes it possible to significantly accelerate the process of manufacturing the above film composite materials. In addition, this improves the adhesion of coating films with inner film. Thus, the inner film may be transparent and/or colored and may have a high level of mechanical properties. Along with this, the coating film may be suitable for laser printing. In this regard, in the present case, it is preferable to use polycarbonate.

However, films made of polycarbonate have the drawback consisting in the fact that the process of layering should be carried out at high temperatures. In addition to stratifying films of polycarbonate necessary for long periods of time. In this regard, are extended above the technological cycles layup and increases the total duration of the production process. Along with this, due to insufficient adhesion of the films to each other during operation of the finished film multilayer material may be splitting.

On the basis of you who izlojennoe the basis of the present invention was based on the objective to offer the film for manufacturing a multilayer systems, which has the necessary mechanical properties and compared with the prior art are characterized by a higher suitability for layering, better traction when layering and improved technological properties. However, such improved film must meet the highest requirements in terms of light transmission, as well as suitability for dyeing and implementation of laser printing.

The specified task has suddenly been solved by the proposed invention is a multilayer composite material, which differs in that it has at least one containing polycarbonate or copolycarbonate film/layer, and a polycarbonate or copolycarbonate further comprises one or more additives selected from the group comprising compounds of the General formula(1)-(8):
