The composite film of the embodiment, the ink layer 15 and the holographic layer 12 are mutually matched, and has various anti-counterfeiting effects. When the ink layer 15 is arranged on the outer side of the holographic layer 12, the surface of the composite film has a bright-color ink effect and a full-plate weak laser effect; when the ink layer 15 is arranged on the inner side of the holographic layer 12, the coating 13 is a transparent coating, and the surface of the composite film has a clear and transparent laser effect and a full-page full-body matte ink effect.
When the ink layer 15 is disposed on the outer side of the hologram layer 12 (for example, the ink layer 15 is disposed on one surface of the base film layer 11), the plating layer may be a transparent plating layer or a colored plating layer. When the ink layer 15 is arranged on the inner side of the holographic layer 12 (e.g. the ink layer 11 is arranged between the coating layer 13 and the glue layer 14), the coating must be a transparent coating. The transparent coating is a titanium dioxide coating, a niobium pentoxide coating, a zirconium dioxide coating, a magnesium fluoride coating or a zinc sulfide coating, or is made of other ceramic materials with the refractive index of more than 1.8.

For example, the holographic anti-counterfeiting micro-nano structure comprises a micro-nano structure with a lens effect and a micro-nano structure with a laser effect, which are locally arranged. The specific structures of the holographic anti-counterfeiting micro-nano structures with unique visual effects (anti-counterfeiting effects) are the prior art, and refer to patents such as a three-dimensional laser printing method and system of patent CN201310166341.1, a two-channel grating structure of patent CN201210002138.6, an identification structure and a card identification method, a safety film with dynamic three-dimensional effects of patent CN201010180251.4, a dynamic amplification optical film of patent CN201510094589.0 plane Fresnel lens array and the like.

The local hollow-out arrangement of the ink layer enables the anti-counterfeiting mark in the designated area of the holographic layer to be clear and transparent and more prominent.
When the ink layer 15 is arranged on the inner side of the holographic layer 12, the ink layer has a full-page full-body matte ink effect due to the existence of the holographic anti-counterfeiting micro-nano structure 121 of the holographic layer 12. Therefore, when a certain image and text or logo on a part of the ink layer needs to be emphasized, in another preferred embodiment, referring to fig. 6, the holographic layer 12 is partially hollowed, the ink layer 15 includes a designated area 151, and the designated area is printed with a specific image, text or logo. The holographic anti-counterfeiting micro-nano structure 121 of the holographic layer 12 is hollowed in a region corresponding to the designated region 151 of the ink layer 15. The local hollow-out arrangement of the holographic layer here means that no micro-nano structure is imprinted at the local hollow-out position 122 of the holographic layer. The arrangement enables the specific pictures and texts of the ink layer arranged on the inner side to present the printing ink effect with vivid colors.

The embodiment also provides an identification card which comprises the composite film provided by the embodiment.
Card with symmetrical structure
The structure of the existing identification card is basically not designed symmetrically, and due to the fact that different materials have different shrinkage rates, the asymmetric design can enable the identification card to be prone to curling or unevenness after the identification card is used for a period of time.

Due to the fact that the same materials have the same shrinkage rate, the card can be even and flat without warping even if the card is used for a long time due to the symmetrical structure.
The contents of the base film layer 11, the holographic layer 12, the plating layer 13 and the glue layer 14 may be referred to the contents of the respective layers of the composite film of the previous embodiment. Because the two composite surface layers of the identification card provided by the embodiment are provided with the holographic layers printed with the holographic anti-counterfeiting micro-nano structures, the identification card provided by the embodiment has a double-sided holographic anti-counterfeiting effect.
In order to make the anti-counterfeiting effect more diversified, as shown in fig. 8, in a preferred embodiment, the identification card further includes an ink layer, and since the thickness of the ink layer is thinner, the symmetry of the material of the composite surface layer of the identification card of this embodiment is not affected, so that the ink layer can be flexibly disposed at some positions of the identification card of this embodiment. For example, the ink layer may be disposed on both sides of the middle layer as shown in fig. 8, or may be disposed on one or both of the composite surface layers, and as for the specific location of the composite surface layer, reference may be made to the location of the ink layer in the composite film of the previous embodiment.

In addition, when the composite film provided in the previous embodiment is disposed on both sides of the middle layer of the identification card as the composite surface layer, the positions of the base film layer 11, the holographic layer 12, the plating layer 13 and the glue layer 14 are symmetrically disposed, but the positions of the ink layers may be asymmetrical, for the reasons stated above, and will not be described in detail here.
Card with incomplete symmetrical structure
The composite surface layer of the card provided by the previous embodiment comprises a plurality of layers, and the thickness of the plating layer is negligible compared with the thickness of other layers (the base film layer, the holographic layer and the adhesive layer) in practice, and the symmetry of the whole card on the material is not influenced.

The certificate card with the incompletely symmetrical structure is characterized in that the thicknesses of the base film layers of the two composite surface layers are the same, the thicknesses of the holographic layers of the two composite surface layers are the same, and the thicknesses of the glue layers of the two composite surface layers are the same, so that even if the holographic layer of one composite surface layer is printed with the holographic anti-counterfeiting micro-nano structure and coated with the coating, the coating is thinner, and the symmetry of the whole certificate card on the material is not influenced. This embodiment thus provides an identification card that is uniformly flat and warp free even after prolonged use due to the same material having the same shrinkage, which is not completely symmetrical.
Like the identification card provided by the previous embodiment, the identification card provided by the embodiment can also increase the diversity of the anti-counterfeiting effect of the identification card by adding the ink layer. As shown in fig. 10, in a preferred embodiment, the identification card further includes an ink layer, and since the thickness of the ink layer is relatively thin, the symmetry of the material of the composite surface layer of the identification card of this embodiment is not affected, so that the ink layer can be flexibly disposed at some positions of the identification card of this embodiment. For example, the ink layer may be disposed on both sides of the middle layer as shown in fig. 8, or may be disposed on one or both of the composite surface layers, and as for the specific location of the composite surface layer including the plating layer, reference may be made to the location of the ink layer in the composite film of the previous embodiment.
It should be noted that the composite film provided in the first embodiment can also be used as a composite surface layer with a plating layer of the identification card provided in this embodiment, and the identification card provided in this embodiment also has more diversified anti-counterfeit effects (for example, the ink layer is hollowed and the holographic layer is hollowed).
The above is only the preferred embodiment of the present invention, and not the scope of the present invention, all the equivalent structures or equivalent flow changes made by the contents of the specification and the drawings or the direct or indirect application in other related technical fields are included in the patent protection scope of the present invention.
