Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention more clear, the technical solutions of the embodiments of the present invention will be clearly and completely described below. The specific conditions are not noted in the examples and are carried out according to conventional conditions or conditions recommended by the manufacturer. The reagents or apparatus used were conventional products commercially available without the manufacturer's attention.
The embodiment of the invention provides a holographic anti-counterfeiting film, a preparation process thereof and a holographic anti-counterfeiting card, and the preparation process is specifically described below.
In the prior art, the holographic anti-counterfeiting pattern is extremely easy to damage in the preparation process of the anti-counterfeiting card, so that the anti-counterfeiting effect is caused. The inventor finds that the reason why the holographic anti-counterfeiting pattern is destroyed may be that the temperature and the pressure are high during lamination, and the lamination temperature exceeds the temperature that the holographic anti-counterfeiting film can bear, so that the anti-counterfeiting film with the holographic anti-counterfeiting pattern is vitrified, and the nano microstructure of the holographic pattern is destroyed by lamination under high temperature and high pressure (1-5 MPa and 180-190 ℃) to lose the anti-counterfeiting effect.
In view of the above, the embodiment of the invention provides a holographic anti-counterfeiting film, which comprises a temperature-resistant protective layer and a temperature-resistant imaging layer, wherein the temperature-resistant protective layer and the temperature-resistant imaging layer are not vitrified at the temperature of 190-200 ℃ under the pressure of 1-5MPa, and the temperature-resistant imaging layer is provided with a holographic anti-counterfeiting pattern and is connected with the temperature-resistant protective layer. The holographic anti-counterfeiting pattern is arranged on the temperature-resistant imaging layer, and the temperature-resistant imaging layer has good high temperature resistance and high pressure resistance, so that the holographic anti-counterfeiting pattern cannot be damaged due to the high temperature or high pressure of lamination when the anti-counterfeiting card is prepared by subsequent lamination, and the integrity of the holographic anti-counterfeiting pattern in the anti-counterfeiting card is further ensured. The temperature-resistant protective layer can produce synergistic effect with the temperature-resistant imaging layer, so that the holographic anti-counterfeiting pattern can not be damaged by high temperature and high pressure during lamination, the integrity of the holographic anti-counterfeiting pattern is guaranteed, and meanwhile, the adhesion force between all layers of the holographic anti-counterfeiting film can be improved by the temperature-resistant protective layer, and the performance of the holographic anti-counterfeiting film is guaranteed.
Further, the thickness of the temperature-resistant imaging layer is 0.8-1.5 micrometers, more preferably 1.0-1.3 micrometers, and the temperature-resistant imaging layer adopts the thickness, so that the temperature resistance and the pressure resistance of the temperature-resistant imaging layer are ensured more favorably.
The thickness of the temperature-resistant protective layer is 0.8-1.5 microns, more preferably 1.0-1.3 microns, and the thickness of the temperature-resistant protective layer is adopted, so that the holographic anti-counterfeiting pattern is protected at high temperature and high pressure.
Further, the vitrification temperature of the cured temperature-resistant imaging layer and the cured temperature-resistant protective layer is 200-220 ℃, and the vitrification temperature of the cured imaging layer and the cured temperature is between the temperatures, so that the resin is prevented from vitrification during lamination, and the structural integrity of the holographic anti-counterfeiting pattern is ensured, and the anti-counterfeiting effect is ensured.
Further, the holographic anti-counterfeiting film further comprises a die pressing imaging layer with holographic anti-counterfeiting patterns, the die pressing imaging layer is arranged between the temperature-resistant protective layer and the temperature-resistant imaging layer, and the die pressing imaging layer is connected with the temperature-resistant imaging layer. The embossed imaging layer can be laminated under high pressure to further protect the holographic anti-counterfeiting pattern. Meanwhile, the anti-counterfeiting material has good molding property and can be molded to form a holographic anti-counterfeiting pattern. And the mould pressing imaging layer plays a certain isolation role, so that the problems of sticking, peeling, fading and the like caused by direct contact mould pressing of the mould and the curing temperature-resistant imaging layer during mould pressing can be avoided, the production effect of the holographic anti-counterfeiting film is guaranteed, the integrity of the holographic anti-counterfeiting pattern on the holographic anti-counterfeiting film is guaranteed, and the integrity of the holographic anti-counterfeiting pattern on a follow-up anti-counterfeiting card is also facilitated.
The mould pressing imaging layer and the temperature-resistant imaging layer form an imaging layer with a holographic anti-counterfeiting pattern. The imaging layer can not be vitrified at the temperature of between 190 and 200 ℃ under the pressure of between 1 and 5MPa, so that the integrity of the holographic anti-counterfeiting pattern is ensured.
Further, the thickness of the embossed imaging layer is 0.1 to 0.5 microns, more preferably 0.1 to 0.3 microns. The thickness of the mould pressing imaging layer is favorable for forming the holographic anti-counterfeiting pattern on the mould pressing imaging layer and the temperature-resistant imaging layer simultaneously during mould pressing, and is also favorable for improving the holographic anti-counterfeiting film to ensure that the holographic anti-counterfeiting pattern cannot be damaged under high temperature and high pressure.
Further, the holographic anti-counterfeiting film also comprises a release layer, and the release layer is connected with one side of the temperature-resistant imaging layer, which is relatively far away from the temperature-resistant protective layer; preferably, the thickness of the release layer is 0.2-0.5 micrometers, and the surface tension of the release layer is 40-52dyn/cm; the release layer ensures good adhesive force with a matrix film of a subsequent anti-counterfeiting card, so that delamination is not easy to occur in an aging stripping test, and the use requirement of the anti-counterfeiting card can be met.
Further, the holographic anti-counterfeiting film also comprises a base film layer, and the base film layer is connected with one side of the release layer, which is relatively far away from the temperature-resistant imaging layer; more preferably, the thickness of the base film layer is 13-23 microns, and the base film layer is a BOPET base film. The base film layer can protect the holographic anti-counterfeiting film before the holographic anti-counterfeiting film is not used.
Further, the holographic anti-counterfeiting film also comprises a plating layer, wherein the plating layer is arranged between the die pressing imaging layer and the temperature-resistant protective layer, and the die pressing imaging layer and the temperature-resistant protective layer are both connected with the plating layer; more preferably, the thickness of the plating layer is
Further, the holographic anti-counterfeiting film also comprises a glue layer, wherein the glue layer is connected with one side of the temperature-resistant protective layer, which is relatively far away from the plating layer, and the thickness of the glue layer is 4-8 micrometers. By adopting the adhesive layer, the adhesive capability of the holographic anti-counterfeiting film and the matrix film of the subsequent holographic anti-counterfeiting card can be improved, meanwhile, the slitting property of the holographic anti-counterfeiting film is improved, the holographic anti-counterfeiting film cannot be yellowing during high-temperature lamination, and the performance of the anti-counterfeiting card is improved.
The embodiment also provides a preparation process of the holographic anti-counterfeiting film: the method comprises the following steps:
And selecting the base film as a base film layer, and coating a release raw material on the base film layer to form a release layer. Wherein the release raw material comprises resin and cellulose, more preferably, the resin is acrylic resin, more preferably, high hydroxyl acrylic resin; the cellulose is hydroxy cellulose; more preferably, the mass ratio of resin to cellulose is 7:1 to 1:1.
