Problems solved by technology

[0002] In order to identify the authenticity of commodities, anti-counterfeit identification materials are often used on commodities. Microlens materials are widely used. Most of the existing microlens materials are microlens arrays with a layer of bumps arranged on the substrate. The microlens array magnifies the pattern on the substrate to realize the identification of authenticity, but the magnification effect of one layer of microlens is relatively small

Embodiment Construction

[0013] All features disclosed in this specification, or steps in all methods or processes disclosed, may be combined in any manner, except for mutually exclusive features and / or steps.

[0014] Any feature disclosed in this specification (including any appended claims, abstract and drawings), unless expressly stated otherwise, may be replaced by alternative features which are equivalent or serve a similar purpose. That is, unless expressly stated otherwise, each feature is one example only of a series of equivalent or similar features.

[0015] Such as figure 1 A naked-eye 3D anti-counterfeiting material as shown includes a base material 1, and the top layer UV varnish 2 and the bottom UV varnish 4 are respectively coated on both sides of the base material 1, and the top layer UV varnish 2 and the bottom UV varnish 4 pass through the The embossing forms the top layer texture 3 and the bottom layer texture 5, the top layer texture 3 and the bottom layer texture 5 are microlens...

Abstract

The invention discloses a naked-eye 3D anti-counterfeiting material. The naked-eye 3D anti-counterfeiting material comprises a base material, the two sides of the base material are coated with UV curable varnish, the UV curable varnish forms upper and lower layers of microlens arrays through embossing, and the upper and lower layers of microlens arrays are staggered. The enlargement effect generated by the dislocation of a top layer texture and bottom layer texture generates different method effects with the difference of light incidence angles, if the bottom texture is 0.01 mm, the texture can be enlarged to 5 mm when the rotation angle reaches 30 degrees, the enlargement effect is significant, a pattern is more stereoscopic, and the naked-eye 3D effect is achieved.

Description

technical field [0001] The invention relates to a naked-eye 3D anti-counterfeiting material. Background technique [0002] In order to identify the authenticity of commodities, anti-counterfeit identification materials are often used on commodities. Microlens materials are widely used. Most of the existing microlens materials are microlens arrays with a layer of bumps arranged on the substrate. The microlens array magnifies the pattern on the substrate to realize authenticity identification, but the magnification effect of a layer of microlenses is relatively small. Contents of the invention [0003] The invention relates to a naked-eye 3D anti-counterfeiting material, which can expand the magnification effect. [0004] To achieve this purpose, the method adopted in the present invention is: a naked-eye 3D anti-counterfeiting material, comprising a substrate, the two sides of the substrate are respectively coated with a top layer of UV varnish and a bottom layer of UV var...
