Detailed Description

Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, like numbers in different drawings represent the same or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present invention. Rather, they are merely examples of methods consistent with certain aspects of the invention, as detailed in the appended claims.

The composite anti-counterfeiting mark and the preparation method thereof provided by the application are explained in detail by specific examples below.

In order to better understand the technical scheme provided by the application, firstly, the raw materials used in the application are briefly introduced.

The anti-counterfeiting fiber used in the application is an anti-counterfeiting material commonly used for anti-counterfeiting paper, the specific form of the anti-counterfeiting fiber is a strip-shaped or ring-shaped fine fiber, and the size of a single anti-counterfeiting fiber is small, so that adverse effects on the identification of pictures and texts printed on a paper-made mark can be avoided. The size and the property of the anti-counterfeiting fiber are similar to those of the paper pulp fiber, so that the anti-counterfeiting fiber can be uniformly dispersed in the paper pulp fiber when being put into the paper pulp fiber, and therefore, the anti-counterfeiting fiber is added into the paper pulp in the papermaking process, and the anti-counterfeiting fiber and the paper fiber are well fused after paper is formed, so that the obtained anti-counterfeiting fiber paper product has an anti-counterfeiting effect. However, the manufacturing process of the anti-counterfeiting fiber paper is complex, the starting scale is large, the raw material loss is large, at least several tons of requirements are needed, a relatively ideal finished product rate can be obtained, even the minimum starting scale is a little cost investment, and the paper requirement of the identification product generally can not reach the minimum starting scale, so that the cost of using the paper anti-counterfeiting identification is too high in terms of the yield-dosage ratio, and the application of the paper anti-counterfeiting identification is greatly restricted by the high paper making cost.

Although the film products can be produced as required, the problem of overlarge starting scale does not exist, but the film anti-counterfeiting products have reproducibility, and dispersed anti-counterfeiting fibers are difficult to be effectively and uniformly added into the film marks due to the limitation of a manufacturing process in the film products, so that the film anti-counterfeiting products are not popular.

Fig. 1 shows a schematic structural diagram of a composite anti-counterfeit mark provided by the present application, and as shown in fig. 1, the composite anti-counterfeit mark includes a top layer film set 1 and a bottom layer film set 2 laminated together.

In this example, the top layer film group 1 and the bottom layer film group 2 are laminated together through a separation layer 3.

In this example, the material of the separation layer 3 may be a release resin, or a material having a similar function to the release resin, so as to ensure that the top layer film group 1 in the composite anti-counterfeit mark can be conveniently and completely removed from the bottom layer film group 2, and the information carried in the bottom layer film group is fully and completely exposed.

Preferably, the thickness of the separation layer 3 is uniform, and the peeling force thereof is 0.1N to 1.0N/25 mm.

It is to be understood that the thickness of the separation layer 3 is not particularly limited in the present application, and is as small as possible under the condition that the peeling force is satisfied.

In this example, the top layer film group 1 includes a coating layer 11, a hologram layer 12, and a first substrate layer 13 laminated in this order.

In this example, the first substrate layer 13 is transparent, so as to shield information carried by the underlayer film group 2, thereby improving the anti-counterfeiting capability.

Specifically, the material of the first substrate layer 13 may be a polymer film, for example, a PET film, alternatively, the thickness of the first substrate layer 13 may be 30 μm to 100 μm, and the specific thickness may be specifically set as needed.

In this example, the holographic text layer 12 may include a printing sublayer 121 and a holographic image sublayer 122 laminated in sequence, and may also include a holographic image sublayer 122 and a printing sublayer 121 laminated in sequence, that is, the sequence of the printing sublayer 121 and the holographic image sublayer 122 may be interchanged.

Specifically, the printing sublayer 121 may be printed on the holographic image sublayer 122, or may be directly printed on the first substrate layer 13.

In this example, the printing sub-layer 121 is a color image and/or a number, such as a specific character, a specific pattern, etc., formed by digital or conventional printing, and has a hollow structure.

Further, the holographic image sublayer 122 is a holographic film layer, and may specifically be a full-page or partial holographic image added by hot stamping or the like, and the holographic image sublayer 122 also bears structures such as specific characters and specific graphics.

In this example, the printing sub-layer 121 and the holographic image sub-layer 122 can form a specific image and text through a specific combination, and the formed specific image and text can further enhance the anti-counterfeiting capability of the composite anti-counterfeiting mark.

The applicant finds that the arrangement sequence of the printing sublayer 121 and the holographic image sublayer 122 has no significant influence on the anti-counterfeiting function of the composite anti-counterfeiting mark, and can be specifically set according to needs.

In this example, the coating layer 11 is transparent or partially transparent, and specifically may be a polypropylene film or a polyester film, which can display information carried by the holographic text layer 12 on one hand and can prevent the holographic text layer 12 from being damaged on the other hand.

In this example, the underlayer film set 2 includes a second substrate layer 21, a substrate graphics layer 22, an adhesive layer 23 and a security fiber layer 24 laminated in this order.

In this example, the first substrate layer 13 and the second substrate layer 21 are separated on two sides of the separation layer 3, and specifically, as shown in fig. 1, the layer structure of the composite anti-counterfeiting mark sequentially includes a coating layer 11, a holographic image-text layer 12, the first substrate layer 13, the separation layer 3, the second substrate layer 21, a substrate image-text layer 22, an adhesive layer 23, and an anti-counterfeiting fiber layer 24.

In this example, the second substrate layer 21 is transparent, the second substrate layer 21 is on the one hand as the base material of bottom layer membrane layer group 2 for bear substrate picture and text layer 22, adhesion layer 23 and anti-fake fiber layer 24, and on the other hand as the tectorial membrane layer of bottom layer membrane layer group 2, after top layer membrane layer group 1 is uncovered, substrate picture and text layer and anti-fake fiber layer can remain intact on the adhesion base member, and no deformation to realize anti-fake function.

Specifically, the material of the second substrate layer 21 may be a UV resin, the thickness of the second substrate layer 21 is not particularly limited in this application, and any thickness is selected under the condition that the performance requirement is met, and it can be understood that the thickness of the second substrate layer is preferably small.

Further, the second substrate layer 21 may be obtained by spraying a liquid UV resin on the separation layer 3 and then curing the resin. The applicant finds that the UV resin has a flat surface after being cured, has certain hardness and good surface tension, and is suitable for printing and jet printing images and texts on the surface of a substrate.

In this example, the substrate graphics layer 22 is printed on the second substrate layer 21. Optionally, the substrate layer 22 is made of a material that does not chemically react with the binder.

Specifically, the substrate image-text layer 22 may be an image-text printed on the surface of the second substrate layer 21 by a conventional method, and may have a hollow structure, and the substrate image-text layer 22 may be embodied in the form of a number, a bar code, a two-dimensional code, or the like.

In the present example, the adhesive layer 23 is used for adhering the composite security device to a target substrate, and specifically, the adhesive includes a butadiene-acrylonitrile rubber modified phenolic resin.

Optionally, the coating thickness of the adhesive layer 23 is 5 μm to 15 μm to ensure that the security fiber can be well adhered to the adhesive.

In this embodiment, the anti-counterfeit fiber layer 24 can be scattered and adhered on the surface of the adhesive layer 23 by means of scattering, and the density of the anti-counterfeit fiber on the surface of the adhesive layer 23 is 0.2-2.0 g/m²So that a large number of adherable regions are left on the surface of the adhesive layer 23, and further, the anti-counterfeiting fiber and the adhesive can be tightly combined by adhering the composite release paper and applying pressure to the composite anti-counterfeiting mark.

In this example, the composite anti-counterfeit mark can be adhered to the release paper layer 4 before use, and if the composite anti-counterfeit mark is used, the release paper layer 4 can be discarded, and the composite anti-counterfeit mark is adhered to a target position.

Alternatively, the release paper layer 4 may be any release paper in the prior art, such as a lafaxine base paper.

In the present application, the composite anti-counterfeit mark may be prepared according to a method including the following steps 1 to 7:

step 1, printing a holographic picture and text on one side of a first substrate.

In this example, the specific implementation manner of this step includes the following two types:

in a first mode, the printing of the hologram on one side of the first substrate specifically comprises:

printing a holographic image on the first substrate;

printing an image on the holographic image.

In another form, printing the hologram on one side of the first substrate specifically includes:

The coating thickness of the resin to be coated is not particularly limited, and may be specifically selected as needed.

Further, the coating method is not particularly limited in the present application, and may be specifically selected according to the material and the need.
