Both the first adhesion promoter layer 42 and the UV varnish layer 44 are coated on the upper and lower surfaces of the ink layer 41 by a coater. The second adhesion promoter layer 43 is coated on the bottom surface of the UV varnish layer 44 by a coater. A second adhesive layer 51 is coated on the top surface of the vacuum aluminized layer 5 by a coater. The second adhesive layer 51 is adhered to the bottom surface of the ink layer 41 through the second adhesion promoter layer 43. The transparent protective layer 3 includes a transparent protective film 31 and a first adhesive layer 32. The transparent protective film 31 is coated on the bottom surface of the separation layer 2 by a coater. The first adhesive layer 32 is coated on the bottom surface of the transparent protective film 31 by a coater. The first adhesive layer 32 is adhered to the top surface of the ink layer 41 through the first adhesion promoter layer 42. Through the settings of the first adhesion promoter layer 42 and the second adhesion promoter layer 43, the bonding strength between the second adhesive layer 51 and the first adhesive layer 32 and the ink layer 41 can be increased. Through the transparent protective film 31 and the UV varnish layer 44, the upper and lower sides of the ink layer 41 can be protected, preventing external water from contacting the ink layer 41, making the pattern after hot stamping have high fold resistance and scratch resistance, and not easily falling off, achieving the purpose of increasing the bonding strength between the coloring layer 4 and the vacuum aluminized layer 5;

[0022] Working principle and usage process of the present utility model: For this high-adhesion hot stamping foil of electroaluminum, during use, first irradiate the UV varnish layer with a UV lamp to harden it, and then hot stamp this electroaluminum hot stamping foil onto the surface of the substrate to be hot stamped. On the surface of the substrate to be hot stamped, there are successively a hot melt adhesive layer 6, a vacuum aluminized layer 5, a coloring layer 4, and a transparent protective layer 3. Through the transparent protective film 31, this electroaluminum hot stamping foil has good scratch resistance. Moreover, after the UV varnish layer 44 is irradiated by the UV lamp, it changes from a liquid state to a solid state, thereby achieving surface hardening and also playing a role in scratch and abrasion resistance. The ink layer 41 can be protected through the UV varnish layer 44, making the ink layer 41 have strong hydrophobicity. Through the setting of the first adhesion promoter layer 42 and the second adhesion promoter layer 43, the bonding strength between the second adhesive layer 51 and the first adhesive layer 32 and the ink layer 41 can be increased.
