Anti-counterfeiting film

Abstract

The invention discloses an anti-counterfeiting film. The anti-counterfeiting film comprises a graphics layer, a transparent basement membrane and a micro lens array layer, wherein the graphics layer and the micro lens array layer are respectively arranged on two opposite surfaces of the transparent basement membrane; the graphics layer comprises a plurality of subunit patterns which are distributed in an array, the subunit pattern of the graphics layer and the region structure uncovered by the subunit pattern are a holographic sketch grating structure or a plane structure, and the subunit pattern is different from the region structure uncovered by the subunit pattern; the micro lens array layer comprises a plurality of micro lenses distributed in the array, and the micro lens of the micro lens array layer is corresponding to the subunit pattern of the graphics layer. Merle amplification images and texts can be imaged by the anti-counterfeiting film; the anti-counterfeiting film has the vertical dynamics, parallel dynamics, floating, sinking, three-dimensional and multichannel effects, and the anti-counterfeiting effect is obvious. The micro lens of the anti-counterfeiting film and the subunit pattern belong to a micron-sized structure and are high in the matching degree, thus the anti-counterfeiting film is more exquisite, high in technical threshold, more difficult to counterfeit and strong in anti-counterfeiting ability.

Description

technical field [0001] The invention relates to the technical field of anti-counterfeiting materials, in particular to an anti-counterfeiting film. Background technique [0002] In order to curb the adverse impact of fake and inferior products on the market economy, in addition to establishing a registered trademark system, it is also necessary to develop anti-counterfeit trademarks to regulate the commodity economy and market development. Anti-counterfeiting trademarks refer to marks that can be transferred to product packaging or accessories by pasting, printing, etc., and have anti-counterfeiting effects. [0003] At present, the existing anti-counterfeiting registered trademarks include laser holographic logo, two-dimensional code anti-counterfeiting, anti-counterfeiting ink printing, etc. These anti-counterfeiting means are easy to understand because of their physical principles, and can be produced industrially, so the production cost is relatively low and is conduciv...
