Embodiment 1

[0040] see figure 1 , is a schematic structural diagram of a holographic anti-counterfeiting element provided by an embodiment of the present invention. For convenience of description, only the parts related to the embodiment of the present invention are shown, and the details are as follows.

[0041] The holographic anti-counterfeit element 100 provided by the present invention includes a film substrate 110, a photopolymer anti-counterfeiting layer 120 and a protective layer 130 stacked in order from top to bottom, and the photosensitive polymer anti-counterfeiting layer 120 is recorded with a volume reflection hologram and a transmission A type rainbow hologram, the volume reflection hologram has full parallax and three-dimensional effects, and the rainbow hologram has color and horizontal stereo parallax effects.

[0042]In some preferred embodiments, the film substrate 110 is one or more blends or copolymers of polyethylene, polypropylene, nylon, polyamide, polycarbonate, ...

Embodiment 2

[0053] see figure 2 , is a flow chart of steps of a method for preparing a holographic anti-counterfeiting element provided by an embodiment of the present invention. For the convenience of description, only the parts related to the embodiment of the present invention are shown, and the details are as follows.

[0054] A method for preparing a holographic anti-counterfeit element provided by the present invention comprises the following steps:

[0055] Step S110: According to the Fresnel hologram master, build the Fresnel hologram shooting optical path.

[0056] In practice, by selecting a suitable physical model, such as a skull, to make a Fresnel holographic master, and building a Fresnel hologram shooting optical path, it is used for the shooting and production of the volume reflection hologram in the transflective integration.

[0057] Step S120: Build a rainbow hologram shooting light path according to the rainbow hologram master.

[0058] In practice, you can choose a...

Embodiment 3

[0067] see image 3 , the present invention also provides a preparation device for a holographic anti-counterfeiting element, comprising a Fresnel hologram photographing optical path of a Fresnel hologram master, and a rainbow hologram photographing optical path comprising a rainbow hologram master; wherein:

[0068] The rainbow hologram shooting light path and the Fresnel hologram shooting light path are respectively irradiated on the photosensitive polymer anti-counterfeiting layer from both sides, and the reference light is incident on the photosensitive polymer anti-counterfeiting layer at the same time to interfere. The photosensitive polymer anti-counterfeit layer is formed and recorded with volume reflection holograms and transmission rainbow holograms.

[0069] The Fresnel hologram shooting optical path and the rainbow hologram shooting optical path form a transflective integrated hologram optical path system, and the transflective integrated hologram optical path syst...

Abstract

The invention provides a holographic anti-counterfeiting element. The holographic anti-counterfeiting element comprises a thin-film base material, a photopolymer anti-counterfeiting layer and a protection layer which are stacked in sequence from top to bottom, the photopolymer anti-counterfeiting layer records a volume reflection hologram and a transmission type rainbow hologram, the volume reflection hologram is has the full parallax and three-dimensional effect, the rainbow hologram has the color and horizontal stereoscopic parallax effect, according to the holographic anti-counterfeiting element, the volume reflection holography characteristics and the rainbow holography characteristics are combined, the accordingly manufactured transflective integrated holographic anti-counterfeiting element achieves the full parallax and three-dimensional effect of the volume hologram and achieves the bright rainbow effect of the rainbow hologram in terms of visual effects, the problem that photopolymer only can be exposed at a time is solved, and in addition, a preparing method and a preparing device of the holographic anti-counterfeiting element are provided.

Description

technical field [0001] The invention relates to the technical field of holographic anti-counterfeiting, in particular to a holographic anti-counterfeiting element, a preparation method and a preparation device. Background technique [0002] With the continuous emergence of new anti-counterfeiting technologies around the world, and the increasing demand of the public for the anti-counterfeiting level of anti-counterfeiting products, anti-counterfeiting technology is constantly changing from traditional static, single and two-dimensional visual effects to dynamic, three-dimensional and colorful ones. The effect extends. Volume reflection holography can not only provide a dynamic and three-dimensional visual effect, but its high-tech production process, unique photosensitive materials, replication equipment, etc. increase the difficulty of counterfeiting, and it is gradually becoming one of the development directions of holographic anti-counterfeiting technology in the future. ...
