In addition, the term "peel strength" in the embodiments of the present application refers to the maximum force required to peel the materials from the contact surface per unit width, and the greater the peel strength, the more difficult the layers are to be peeled from each other; in the embodiment of the present application, "the peel strength between the structural layer 200 and the first image-forming layer 300 is smaller than that between other layers" even though it is described that the peeling between the structural layer 200 and the first image-forming layer 300 is most easily performed.
In the embodiment of the present application, the base film layer 100 provides a substrate for the structural layer 200, the structural layer 200 may be coated on the base film layer 100, and then other functional layers are sequentially coated on the structural layer 200. The material of the base film layer 100 may be a biaxially oriented polyester film or a biaxially oriented polypropylene film. The biaxially oriented polyester film has high mechanical strength and good optical performance, and the biaxially oriented polypropylene film has good barrier performance and better gas barrier property and moisture resistance; in this embodiment, the base film layer 100 is made of a biaxially oriented polyester film. In addition, the thickness of the base film layer 100 may be 10 to 30 μm, such as 10 μm, 15 μm, 20 μm or 30 μm, and the thickness of the base film layer 100 in this embodiment is 10 μm.
In the embodiment of the present application, the surface of the structural layer 200 close to the first imaging layer 300 is provided with a groove structure 210, which can be used as a template for the first imaging layer 300. The material of the structure layer 200 may be UV resin, the thickness may be 1.2-1.5 μm, and the depth of the groove structure 210 in the structure layer 200 may be 0.8-1.2 μm. In this embodiment, the material of the structural layer 200 is UV resin, the thickness is 1.5 μm, and the depth of the groove structure 210 is 0.8 μm.
It should be noted that in other embodiments, the material of the first imaging layer 300 may also be a mixture of UV resin and silicone-based additives.
In the embodiment of the application, the first imaging layer 300 is superposed with the structural layer 200, and the groove structure 210 on the structural layer 200 is used as a template, and the first micro image-text array 310 is obtained by copying on the surface close to the structural layer 200, and the first micro image-text array 310 can play an anti-counterfeiting effect; meanwhile, the first imaging layer 300 is arranged on the second imaging layer 400 in an overlapped mode, so that the second imaging layer 400 cannot be damaged, and the second imaging layer 400 cannot be easily counterfeited. The material of the first imaging layer 300 in the embodiment of the present application may be UV resin, and the thickness may be 1.2-1.5 μm, for example, 1.2 μm, 1.3 μm, 1.4 μm, or 1.5 μm. Illustratively, the material of the first imaging layer 300 in this embodiment is a UV resin with a thickness of 1.3 μm.
In addition, the peeling strength between the structural layer 200 and the first imaging layer 300 in the embodiment of the application is smaller than that between other layers, so that the structural layer 200 is easily peeled from the first imaging layer 300, the structural layer 200 and the base film layer 100 are conveniently recycled, other functional layers (i.e. the functional layers except the base film layer 100 and the structural layer 200, see fig. 2) of the anti-counterfeiting hot stamping film 001 are conveniently transferred to a product needing film pasting, and the structural layer 200 also plays a role of a release layer at this time; in order for the structural layer 200 to function as a "release layer," the cross-linking density and surface properties of the UV resin material of the first imaging layer 300 may be adjusted to control the peel strength between the structural layer 200 and the first imaging layer 300. The peel strength between the structural layer 200 and the first imaging layer 300 can be 0.1-0.65N/cm. Illustratively, the peel strength between the structural layer 200 and the first imaging layer 300 in this application is 0.1N/c m.
In this embodiment, the second imaging layer 400 with the second micro-image 410 array can also be used for anti-counterfeit purposes. Since the second microimage array 410 on the second imaging layer 400 is embossed at a later stage of fabrication and not directly replicated from the template, the structure of the second microimage array 410 is more difficult to replicate. Set up second imaging layer 400 in anti-fake thermoprint membrane 001 and can promote anti-fake effect of anti-fake thermoprint membrane 001. Furthermore, to ensure that the second imaging layer 400 in the embodiments of the present application is difficult to counterfeit, the second imaging layer 400 is designed to react in contact with water or air for extended periods of time to avoid its counterfeit; the first image-forming layer 300 is in direct contact with air and can protect the second image-forming layer 400, so that the materials of the first image-forming layer 300 and the second image-forming layer 400 are different.
Illustratively, the material of the second imaging layer 400 is an amine-modified polyether acrylate; the amine-modified polyether acrylate reacts upon contact with water or air for a long time to cause the second micro pattern array 410 on the surface to be damaged, and thus it is difficult to peel the second image forming layer 400 off to imitate the second micro pattern array 410 on the surface. In addition, the thickness of the second image forming layer 400 may be 3 to 5 μm. Illustratively, the thickness of the second imaging layer 400 in this embodiment is 3 μm. In addition, in this embodiment, the height of the second micro-image and text array 410 is 1 μm. In other embodiments, the height of the second micro-image-text array 410 can be 2 μm or 3 μm, which only needs to be within 1-3 μm.
In the embodiment of the present application, the plating layer 500 can protect the second imaging layer 400 from being damaged by other functional layers; and the decorative effect can be achieved, so that the patterns are more attractive and bright. The material of the plating layer 500 may be metal, such as Al, or other transparent semiconductor material, such as zinc sulfide. The thickness of the plating layer 500 may be 0.03 to 0.05 μm. Illustratively, in this embodiment, the dielectric of the second imaging layer 400 is metallic Al and has a thickness of 0.03 μm.
In the embodiment of the application, the adhesive layer 600 has viscosity, and when the anti-counterfeiting hot stamping film 001 is transferred to the surface of an object, the anti-counterfeiting hot stamping film 001 can be attached to the surface of the object through the adhesive layer 600, so that the object has an anti-counterfeiting effect; the adhesive layer 600 may be made of thermosetting resin and has a thickness of 0.6-2 μm. In the present embodiment, the material of the glue layer 600 is thermosetting resin, and the thickness is 0.6 μm.
The embodiment also provides a preparation process of the anti-counterfeiting hot stamping film 001, which comprises the following steps:
a biaxially oriented polyester film with a thickness of 10 μm is used as the base film layer 100;
coating UV resin on the lower surface of the base film layer 100 by using a UV molding press, and performing UV molding and UV curing to obtain a structural layer 200 with the thickness of 3 microns, wherein the surface of the structural layer 200, which is close to the first imaging layer 300, is provided with a groove structure 210, and the depth of the groove structure 210 is 1 micron;
uniformly coating UV resin on the lower surface of the structural layer 200 by using a UV molding press, directly carrying out UV photocuring without molding to obtain a first imaging layer 300 with the thickness of 3 mu m, wherein the first imaging layer 300 is close to the structural layer 200 and can copy a groove structure to form a first micro image-text array 310;
controlling the peel strength between the structural layer 200 and the first imaging layer 300 to be 0.1N/cm by adjusting the crosslinking density and the surface characteristics of the UV resin;
uniformly coating amine modified polyether acrylate on the lower surface of the first imaging layer 300 by using a UV molding press, and performing UV molding and UV curing to obtain a second imaging layer 400 with the thickness of 0.8 mu m, wherein a second micro image-text array 410 is molded on the lower surface of the second imaging layer 400;
evaporating Al on the lower surface of the second image forming layer 400 using a vacuum aluminum plating machine to prepare a plating layer 500 having a thickness of 0.03 μm;
thermosetting resin is coated on the plating layer 500 as a glue layer 600, and the thickness of the glue layer 600 is 0.6 μm.
The anti-counterfeiting hot stamping film 001 in the embodiment can be used for tearing off the base film layer 100 and the structural layer 200, leaving other functional layers (see fig. 2), and then transferring the remaining functional layers and pasting the remaining functional layers to an object needing to be pasted with a counterfeit prevention mark through the glue layer 600 to achieve an anti-counterfeiting effect.
The second micro image-text array 410 in the second imaging layer 400 in the anti-counterfeiting hot stamping film 001 provided by this embodiment is not obtained by directly copying a template, and the first imaging layer 300 is further superimposed on the surface of the second imaging layer 400, so that the structure of the second micro image-text array 410 is difficult to copy and copy; first imaging layer 300 and second imaging layer 400 combined action can promote anti-fake effect of anti-fake thermoprint membrane 001. Meanwhile, the second image forming layer 400 of amine-modified polyether acrylate is easily reacted by contacting air for a long time to destroy the second micro image-text array, so that it is difficult to peel the second image forming layer 400 to imitate the second micro image-text array 410 on the surface thereof.
Second embodiment

In this embodiment, the anti-counterfeiting hot stamping film 001 in the first embodiment is attached to the substrate 700, and then the base film layers 100 and 200 are removed, so as to obtain the anti-counterfeiting product 002. Because the peeling strength between the substrate 700 and the adhesive layer 600 is greater than the peeling strength between the structural layer 200 and the first imaging layer 300, the structural layer 200 and the first imaging layer 300 can be peeled without affecting other functional layers, the anti-counterfeiting product 002 still has an anti-counterfeiting effect, and the peeled base film layer 100 and the structural layer 200 can be reused to prepare a new anti-counterfeiting hot stamping film 001 (see fig. 3), so that the preparation cost of the anti-counterfeiting hot stamping film 001 can be saved. Specifically, the peel strength between the substrate 700 and the glue layer 600 in this example was 0.66N/cm.
In other embodiments, the peel strength between the substrate 700 and the subbing layer 600 may also be 0.67N/cm, 0.7N/cm, etc., as long as the peel strength between the substrate 700 and the subbing layer 600 is greater than the peel strength between the structural layer 200 and the first imaging layer 300.
The above description is only an example of the present application and is not intended to limit the scope of the present application, and various modifications and changes may be made by those skilled in the art.
