[0029] In order to facilitate understanding of the utility model, the utility model will be described more fully below with reference to the relevant drawings. The preferred embodiments of the utility model are shown in the drawings. However, the utility model can be realized in many different forms and is not limited to the embodiments described below. On the contrary, the purpose of providing these embodiments is to make the disclosure of the utility model more thorough and comprehensive.
[0030] It should be noted that when an element is referred to as "provided on" another element, it can be directly on the other element or there can be a middle element. When an element is referred to as "connected" to another element, it can be directly connected to the other element or there can be a middle element. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only and are not intended to be the only implementation.
[0031] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which the utility model belongs. The terms used in the specification of the utility model herein are only for the purpose of describing specific embodiments and are not intended to limit the utility model. The term "and / or" used herein includes any and all combinations of one or more related listed items.
[0032] A dynamic graphic text optical film can be applied to packaging, labels, anti-counterfeiting and other products, characterized in that the dynamic graphic text optical film comprises:
[0033] A substrate, the substrate including a first surface and a second surface disposed opposite thereto; the substrate may be made of materials such as PET, PMMA, glass, label paper, etc., or may directly be a polymer layer, such as a thermosetting adhesive or a photocuring adhesive. The function of the substrate is to serve as a carrier. The substrate may be colorless or colored, and the properties of the substrate can be determined according to different usage scenarios;
[0034] A graphic structure, the graphic structure being located on the first surface of the substrate, the graphic structure including a first sub-graphic and a second sub-graphic; the graphic structure may be a pattern, text, or a combination of pattern and text; the first sub-graphic and the second sub-graphic may be independent graphics. For example, the first sub-graphic is the Chinese character "印" and the second sub-graphic is the Chinese character "象"; or the first sub-graphic and the second sub-graphic combine to form a complete graphic to be displayed. For example, the first sub-graphic is the left part of the Chinese character "印" and the second sub-graphic is the right part of the Chinese character "印", so that the first sub-graphic and the second sub-graphic combine to form a complete Chinese character "印";
[0035] The first sub-graphic includes a plurality of first micro-nano graphics, the first micro-nano graphics including a plurality of first micro-nano textures, and the first micro-nano textures are arranged according to a first rule; here, the first rule arrangement may be a preset arrangement method. For example, the arrangement method of the first micro-nano textures in a single first micro-nano graphic is as follows: Assume that the first micro-nano graphic is a circle, and take the leftmost vertex of the first micro-nano graphic as a fixed point (assume this fixed point is a solid circle). The first micro-nano textures are arranged to the right of the fixed point with the fixed point as the reference point. All the first micro-nano graphics forming the first sub-graphic are set in the same way.

For example, the arrangement method of the second micro-nano textures in a single second micro-nano graphic is as follows: Assume that the second micro-nano graphic is a circle, and take the rightmost vertex of the second micro-nano graphic as a fixed point (assume this fixed point is a solid circle). The second micro-nano textures are arranged to the left of the fixed point with the fixed point as the reference point. All the second micro-nano graphics forming the second sub-graphic are set in the same way. In this way, when people observe the second sub-graphic, they will change to the left of the fixed point with the fixed point as the reference point, achieving the effects of dynamic change and color transformation;
[0037] Wherein, according to the arrangement mode described above, it can be seen that the first rule is different from the second rule; here, only an enumeration is made, and an enumeration is not exhaustive, and it can also be arranged around the center of the circle as a reference point; Preferably, the arrangement mode of the micro-nano texture of a sub-graphic is the same, and there is another sub-graphic different from the sub-graphic arrangement, so as to display different dynamic effects, and the change effect is more rich.

[0041] As a further improved technical scheme of the utility model, the first sub-graphic and the second sub-graphic are embedded or convex on the surface of the polymer layer. The first sub-graphic and the second sub-graphic can be formed by embossing, or can be formed by photolithography technology, or laser direct writing to form a sub-graphic.

As a further improved technical scheme of the utility model, the spacing between the first sub-graphic and the second sub-graphic is provided with a holographic structure.
