Description

Technical Field

[0001] This utility model belongs to the field of transfer material technology, and in particular to an AR anti-reflective holographic laser medium hot stamping film. Technical Background

[0002] Holographic laser hot stamping film is a novel transfer material with transparent holographic laser graphic effects. It can highlight graphic logos and appearance, and has anti-counterfeiting properties, leading to increasingly diversified applications. However, due to technological limitations, conventional holographic laser hot stamping film suffers from insufficient light transmittance of the stamped graphics due to the interaction between different coatings, significantly affecting the original color of the substrate. These limitations hinder the product's promotion in some application areas. Utility Model Content

[0003] The purpose of this invention is to provide an AR anti-reflective holographic laser medium hot stamping film to overcome the shortcomings of the prior art.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0005] An AR anti-reflective holographic laser medium hot stamping film is characterized in that it comprises at least one BOPET film substrate, and a resin release layer, an AR anti-reflective layer, a holographic laser layer, a medium layer, and a transparent adhesive layer are sequentially coated on one side of the film substrate.

[0006] The AR antireflective holographic laser medium hot stamping film is characterized by the following: the main component of the resin release layer is thermoplastic high-gloss acrylic resin, which can effectively separate from the BOPET film substrate under the combined action of a certain temperature and peel force; the AR antireflective layer is a transparent coating composed of magnesium fluoride, which can effectively reduce light reflection and increase light transmittance; the main components of the holographic laser layer are thermoplastic polyurethane and thermosetting polyurethane, which can realize holographic laser graphic effects; the medium layer is a transparent coating composed of zinc sulfide, which can fix the holographic laser grating graphic; and the main components of the transparent adhesive layer are thermoplastic polyester resin and cellulose resin, which are the main body for effective adhesion between the hot stamping graphic and the hot stamping substrate.

[0007] The beneficial effects of this utility model are: it effectively improves the light transmittance of the holographic laser medium hot stamping film and greatly reduces the impact of the hot stamping pattern on the original color of the substrate. Attached Figure Description

[0012] The following are specific embodiments of the present invention, and the technical solution of the present invention will be further described in conjunction with the accompanying drawings:

[0013] See Figure 1 The present invention discloses an AR antireflective holographic laser medium hot stamping film, characterized in that it comprises at least one BOPET film substrate 1, on which a resin release layer 2, an AR antireflective layer 3, a holographic laser layer 4, a medium layer 5, and a transparent adhesive layer 6 are sequentially coated. The resin release layer 2 is coated onto the surface of the BOPET film substrate 1 using a coating machine, with a coating mainly composed of thermoplastic high-gloss acrylic resin. The AR antireflective layer 3 is uniformly sputtered onto the surface of the resin release layer 2 using a vacuum sputtering device. The holographic laser layer 4 is coated onto the surface of the AR antireflective layer 3 using a coating machine, with a mixed coating mainly composed of thermoplastic polyurethane and thermosetting polyurethane, and then obtained through a holographic molding process. The medium layer 5 is uniformly vapor-deposited onto the surface of the holographic laser layer 4 using an aluminum plating device. The transparent adhesive layer 6 is coated onto the surface of the medium layer 6 using a coating machine, with a mixed coating mainly composed of thermoplastic polyester resin and cellulose resin.

[0014] See Figure 2 After the hot stamping is applied to the surface of the substrate, the surface of the substrate 7 has, in sequence, a transparent adhesive layer 6, a dielectric layer 5, a holographic laser layer 4, an AR anti-reflection layer 3, and a resin release layer 2. The resin release layer 2, under the combined action of a certain temperature and peeling force, can effectively separate from the BOPET film substrate. The AR anti-reflection layer 3 can effectively reduce light reflection and increase light transmittance. The holographic laser layer 4 can realize holographic laser graphic effects. The dielectric layer 5 can fix the holographic laser grating graphics. The transparent adhesive layer 6 is the main body for effectively bonding the hot stamping graphics and the substrate.
