Zusammenfassung: | The holographic anti-counterfeiting hot stamping film comprises a base material layer, a release layer, a wear-resistant layer, an imaging layer A, a semi-reflective and semi-permeable layer, an imaging layer B, a total reflection layer and a super glue layer from top to bottom, the imaging layer A is provided with a deep concave position hologram image and a shallow concave position hologram image which are subjected to compound die pressing; the formed double-image holographic anti-counterfeiting film has the anti-counterfeiting effect of a deep-concave holographic image and the anti-counterfeiting effect of a shallow-concave holographic image at the same point, the holographic effect is rich, and a better anti-counterfeiting effect is formed by combining the two anti-counterfeiting effects; the imaging layer B is a plastically variable organic medium coating, at least one surface or the interior of the imaging layer B is provided with a plurality of steps with different heights, thesemi-reflecting and semi |
