Example (b):

referring to fig. 1, the high brightness hot stamping film in the preferred embodiment of the present invention includes a base film layer 1, a UV layer 2, a color layer 3, a metal plating layer 4 and a glue layer 5, which are sequentially stacked in the thickness direction.

Specifically, in the preferred embodiment, the outermost side of the highlight hot stamping film is the base film layer 1, which is preferably a biaxially oriented polyester film or a biaxially oriented polypropylene film, and the UV layer 2 has strong adhesion, so that an integral structure with good adhesion can be formed with the base film layer 1, and the UV layer 2 can be completely peeled off from the color layer 3 when the base film layer 1 is torn off, so that the surface of the color layer 3 becomes the surface of the highlight hot stamping film.

It can be understood that, in the actual setting, the peeling strength between the UV layer 2 and the color layer 3 is preferably set to be smaller than that between other layers, so that the accurate peeling between the UV layer 2 and the color layer 3 can be ensured, the adhesion stability between other layers in the process of peeling the base film layer 1 is ensured, and the structural reliability in the use process of the film structure is ensured.

Further, the UV layer 2 in the preferred embodiment is made of a UV curable resin, and the color layer 3 is preferably made of a heat curable resin.
