Example Embodiment

[0036] Example one

[0037] Such as figure 1 As shown, the anti-counterfeiting film includes a three-dimensional holographic layer and a reflective information layer. The three-dimensional holographic layer includes a three-dimensional holographic film 2 made of photosensitive material and recorded with three-dimensional graphic information. The reflective information layer includes a reflective information layer. A retro-reflective film a and a reflective information film 7 made of photosensitive material and recorded with reflective graphics and text. The reflective information film 7 is made of acrylic monomer, and an object is implanted in the retro-reflective film. The bottom of the lower adhesive layer is coated with a thickness of 10-60 nm.

[0038] The retro-reflective film a includes an implant 5 for refraction, an adhesive layer 4 for embedding the implant 5, and a retro-reflective layer 6 for reflecting light, wherein the retro-reflective layer 6 is made of high reflec...

[0047] Example two

[0048] Such as figure 2 As shown, the anti-counterfeiting film includes a three-dimensional holographic layer and a reflective information layer. The three-dimensional holographic layer includes a three-dimensional holographic film 2 made of photosensitive material and recorded with three-dimensional graphic information. The reflective information layer includes a reflective information layer. The retro-reflective film a and the reflective information film 7 made of materials with different refractive indexes by sputtering and recorded with reflective graphic information and having a reflective effect at the same time. The reflective information film 7 is made of metal Cr and MgF respectively by sputtering to make. Then, 15nm and 50nm thick coatings were sputtered on the bottom surface of the adhesive layer 4 under the implant 5, respectively.

[0049] The retroreflective film a includes an implant 5 for refraction, an adhesive layer 4 for embedding the impla...

[0057] Example three

[0058] Such as image 3 As shown, the anti-counterfeiting film includes a three-dimensional holographic layer and a reflective information layer. The three-dimensional holographic layer includes a three-dimensional holographic film 2 made of photosensitive material and recorded with three-dimensional graphic information. The reflective information layer includes a reflective information layer. A retro-reflective film a and a reflective information film 7 made of photosensitive material and recorded with reflective graphics and text. The reflective information film 7 is made of acrylic monomer, and an object is implanted in the retro-reflective film. The bottom of the lower adhesive layer is coated with a 60nm thick coating.

[0059] The retro-reflective film a includes an implant 5 for refraction, an adhesive layer 4 for embedding the implant 5, and a retro-reflective layer 6 for reflecting light, wherein the retro-reflective layer 6 is made of high reflecti...

Abstract

This invention relates to one anti-false film, which comprises space holographic layer and reflection layer, wherein, the front comprises space information film with light sensing materials; the reflection layer comprises strengthening reflection effect regress film and the reflection information film with reflection graphic information. The process method comprises the following steps: independently processing the said holographic layer and reflection layer; then locating one layer to connect medium layer between holographic layer and reflection layer; finally combing the space holographic layer and said reflection layer.

Description

technical field [0001] The invention relates to an anti-counterfeit film applied in the field of anti-counterfeit technology, in particular to an anti-counterfeit film with dual characteristics of three-dimensional holography and reflective information changing with viewing angle and a preparation method thereof. Background technique [0002] In daily life, in order to prevent their products from being counterfeited, merchants usually paste various anti-counterfeiting marks on their products, such as barcodes on brand-name tobacco and alcohol, car film on high-end cars or steel stamps on electrical products At the same time, government departments often attach some unique anti-counterfeiting marks to the driver's license, degree certificate or business license issued by them to prevent counterfeiting; The certificates with anti-counterfeiting marks are getting more and more attention. For example, my country has begun to implement a new generation of re...
