Embodiment 1

[0031] Such as figure 1 As shown, a micro-nano optical 3D dynamic anti-counterfeiting film of the present invention includes an image layer, an intermediate filling layer, and a microlens layer that are sequentially stacked from top to bottom. The intermediate filling layer is a transparent filling layer for adjusting the focal length, and the microlens A plurality of evenly distributed microlenses are arranged on the layer.

[0032] For the light wave emitted by the trademark on the image layer, it first passes through the transparent filling layer to adjust the focal length, then enters the microlens layer, and after focusing, imaging, adjusting and transforming the microlens layer, it is presented in the customer's field of vision. , the anti-counterfeiting label can obtain a three-dimensional and dynamic display effect that subverts the sensory perception of the human eye. It can be widely used in various daily products and financial and legal documents in various forms s...

Embodiment 2

[0034] This embodiment is preferably as follows on the basis of Embodiment 1: the distance between any two adjacent micro-lenses is in the range of 30 μm-1 mm. It is used to strengthen the diameter depth of the light wave emitted by the anti-counterfeiting label, enhance the dynamic effect, and attract customers' attention.

[0035] The aperture size of each microlens ranges from 10 μm to 100 μm. It is used to strengthen the diameter depth of the light wave emitted by the anti-counterfeiting label, enhance the dynamic effect, and attract customers' attention.

[0036] The middle filling layer is a transparent layer of PVC material. The transparent layer of PVC material is light, waterproof and moisture-proof, flame-retardant and heat-insulating, and can increase the service life of the anti-counterfeiting label.

[0037] The image layer is a transparent layer. The anti-counterfeiting label can better use the microlens layer for optical processing to achieve better optical e...

Embodiment 3

[0039] A manufacturing process of micro-nano optical 3D dynamic anti-counterfeiting film, comprising the following steps:

[0040] Step A) dividing the surface of the microlens array into a plurality of microlens units, and numbering each microlens unit one by one to form a plurality of microlens masks;

[0041] Step B) Process the surface of one or more microlens masks by laser direct writing according to the predetermined pattern to obtain the slit of the predetermined pattern;

[0042] Step C) each processed microlens mask is placed in an independent mobile device and each mobile device works independently, one or more processed microlens masks are placed in parallel on the photoresist surface, Under the action of a 300W-500W mercury lamp, move one processed microlens mask one by one through the photoresist surface for exposure, and then move the next processed microlens mask through the photoresist surface for exposure until The surface of the photoresist completes the pr...

Abstract

The invention discloses a micro / nano optical 3D dynamic anti-fake film and a manufacturing method. The micro / nano optical 3D dynamic anti-fake film includes an image layer, an intermediate filling layer and a micro lens layer which are sequentially stacked from top to bottom. The intermediate filling layer is a transparent filling layer for adjusting the focal length, and the micro lens layer is provided with a plurality of evenly-distributed micro lenses. Through the principle, the micro / nano optical 3D dynamic anti-fake film can present a three-dimensional and dynamic display effect to customers, the customers' attention is attracted well, patterns high in complexity can also be formed to improve grade of an anti-fake mark, and the manufacturing difficulty of the anti-fake mark is also greatly improved.

Description

technical field [0001] The invention relates to the field of anti-counterfeiting technology, in particular to a micro-nano optical 3D dynamic anti-counterfeiting film and a manufacturing process. Background technique [0002] As early as 1700, Europe printed the first labels for identification of goods on medicines and cloth. Therefore, the current label is used to mark the product target and category or content, such as the keywords determined for the target, and it is a tool for finding and locating the target. The label that printing industry is called, mostly is the printed matter that is used to identify the related description of own product, and most of them all have glue on the back side. But there are also some that are printed without glue, which can also be called labels, and the labels with glue are commonly known as self-adhesive labels. The labeling of the instrument after calibration is a label uniformly stipulated by the country. The label can clearly expla...
