Abstract

The utility model discloses a holographic false proof card-protecting film comprising a plastic carrier thin film, a separation layer, an imaging layer, an media layer and a sticking adhesive layer, which are superposed in turn, and is characterized in that a protecting layer is arranged between the separation layer and the imaging layer. The holographic false proof card-protecting film has the characteristics as follows: (1) due to the installation of the protecting layer between the separation layer and the imaging layer, a transparent scratch-proof protecting layer comes into being on the surface of the imaging layer after the occurrence of transfer, thus the protecting layer can lead the card-protecting film to be durable in use and newer with time; (2) the holographic false proof card-protecting film is part-transferable, which can not only be used on base materials as a full page or large area, but also can be partially transferred to materials with various sizes and shapes, thereby technical content in the holographic false proof film is strengthened.

Description

A kind of holographic false proof card-protecting film

Technical field

The utility model belongs to the antiforge laser holographic technology, be specifically related to a kind of wear-resistant, can the local holographic false proof card-protecting film that shifts.

Background technology

Under the background of global economic integration, counterfeit and shoddy goods have become global problem.In New York, in November, 2005, U.S.'s ready-made clothes and footwear association held 2 days by a definite date, theme as the seminar of " brand and counterfeit predicament ", just counterfeit and the global subject under discussion of the impact of the industry of making discussed, at the major country of counterfeit brand, the development tactics and the available international resource of U.S. government,, handle counterfeit problem from aspects such as legislation, rules, tariff and brand identifications.In Guangzhou, patriot, Benq, a plurality of MP3 brands salable of three magnitudes are without exception at the product of finding that on the market many moneys " are mixed the spurious with the genuine ".In Beijing, in September, 2005,5 tame high-grade fashion famous brands such as Burberry, fragrant Nai Er, ancient strange, LV and Prada lodge a complaint, and charge the plagiarization that this product is subjected to being positioned at some owners of Xiu Shui market.Through the Chinese Civil adjudication, above-mentioned 5 tame famous brands are won a lawsuit.In Shanghai, the chain net of the U.S. " Startbuck " coffee is won go together owner's the lawsuit with a family.Brand is counterfeit not only in the U.S., all is the problem of making us feeling headache in China, European Union, Ya Zhou, in all parts of the world.Although each family adopts various measures one after another, counterfeit phenomenon is not controlled effectively.

At present, certificate, the certificate of personation are seen everywhere at home.The certificate of personation, certificate have brought inconvenience for people's productive life, have hindered social progress and development greatly.Therefore need a kind of have high anti-counterfeiting power, long-lived, can go up the false proof card-protecting film that uses in shape and the base material that varies in size (certificate, certificate).

Summary of the invention

The purpose of this utility model is to provide a kind of holographic false proof card-protecting film, and that this false proof card-protecting film has is wear-resistant, can the local characteristics that shift, and has better antifalse effect.

The holographic false proof card-protecting film that the utility model provides comprises the plastic carrier film, separating layer, imaging layer, dielectric layer and the glue line that superpose successively, it is characterized in that: be provided with protective layer between separating layer and the imaging layer.

The utlity model has following characteristics: (1) is in the utility model; having increased one deck between separating layer and imaging layer is the protective layer of material of main part with the functional high molecule material; after shifting; the surface of imaging layer has the protective layer of layer of transparent, rub resistance, and this layer protective layer will make that card-protecting film is durable in use, sustain its quality through age.(2) the utility model be a kind of can the local holographic anti-counterfeiting film that shifts, it both can justifying was large-area be applied on the base material, also can partly transfer on different sizes, the different materials, had strengthened the technology content of holographic anti-counterfeiting film.

Description of drawings

Fig. 1 is the structural representation of holographic false proof card-protecting film of the present utility model;

Fig. 2 was the schematic diagram that the false proof card-protecting film of wear-resistant local transfer holographic and base material stickup and plastic sheeting separate with protective layer when moulding.

The specific embodiment

Below by will describing the present invention more in detail by following examples, and following examples only are illustrative, and the present invention is not subjected to the restriction of these embodiment.

As shown in Figure 1, the utility model holographic false proof card-protecting film comprises plastic carrier film 1, separating layer 2, protective layer 3, imaging layer 4, dielectric layer 5 and the glue line 6 of stack successively.

Generally, the plastic carrier film 1 general PET plastic sheeting that adopts, thickness is generally 15 μ m or 19 μ m.Separating layer 2 adopts the polyolefin resin material, and its thickness almost can be ignored.Protective layer 3 is a kind of material of transparent rub resistance, as: polyurethane.Imaging layer 4 adopts the polyacrylate resinous materials, again because of having different requirements different to color, surface abrasion resistance and chemical resistance, adopts contour forging technology that hologram pattern is molded on the imaging layer 4 usually, and its thickness is about 0.5 μ m.The geometric thickness of dielectric layer 5 is 0.6-0.8 μ m.Glue line 6 is a transfer adhesive, and its thickness is 1-1.8 μ m.

Imaging layer 4 can also adopt some special technique except common hologram image is arranged, as photochemical embossment technology, spectral transformation encryption technology, machine-readable technology etc., in order to improve the anti-counterfeiting power of holographic film.

Glue line 6 can will have the imaging layer strong bond of anti-counterfeiting information at card face.

During preparation the utility model, separating layer is coated on the plastic sheeting, on separating layer, is coated with protective layer then, on protective layer, be coated with imaging layer again.The plastic sheeting that will scribble separating layer, protective layer and imaging layer is again delivered to and is carried out mold pressing on the moulding press, and hologram pattern is impressed on the imaging layer.Next step is exactly to be printed on the imaging layer of hologram pattern plating dieletric reflection layer, will seem very bright of the hologram after plating medium on the imaging layer.Because dielectric layer extremely thin (only being 0.6 ~ 0.8 μ m),, can see information such as pattern below the card-protecting film and literal clearly so whole card-protecting film remains transparent.

As shown in Figure 2, during transfer, wear-resistant local transfer holographic anti false film is placed on the surface of base material 7, shifting glue-line contacts with document surface, acting on temperature after pressure roller 8 is heated and pressurizeed becomes on the holographic anti-counterfeiting film, the temperature of pressure roller makes the transfer adhesive fusing, and protective layer 3, imaging layer 4 and dielectric layer 5 are bonded in substrate surface; The temperature of pressure roller makes separating layer 2 fusings, and plastic film layers 1 separates with protective layer 3, and the imaging layer that just will record hologram has been stayed substrate surface.

The utility model not only is confined to the above-mentioned specific embodiment; persons skilled in the art are according to the disclosed content of the utility model; can adopt other multiple specific embodiment to implement the utility model; therefore; every employing project organization of the present utility model and thinking; do some simple designs that change or change, all fall into the scope of the utility model protection.
