Embodiment Construction

[0027] Hereinafter, the present application will be described in detail through embodiments and with reference to the accompanying drawings.

[0028] Anti-counterfeiting film technology is a new type of optical anti-counterfeiting technology, which has a high public recognition effect. It is mainly used for anti-counterfeiting of banknotes, securities, passports, tax stamps and other high-end security products. Its main purpose is to integrate holographic and optical variable anti-counterfeiting features, achieve multiple anti-counterfeiting effects through special structural design, and further improve the anti-counterfeiting level.

[0029] figure 1 and figure 2 The structural schematic diagrams of the anti-counterfeiting films according to the embodiments of the present application are respectively shown. As shown in the figure, the anti-counterfeiting film includes a substrate layer 1 stacked in sequence, a holographic imaging layer 2 with a holographic image, a partia...

Abstract

The invention provides an anti-fake film comprising a base material layer (1), a holographic imaging layer (2) with holographic images, a partially-hollow brightening layer (3) and a light variation composite structure which are sequentially superposed, wherein the light variation composite structure presents a colour at one viewing angle and presents two different colours at the other viewing angle; the light variation composite structure comprises a first layer and a second layer; the first layer is arranged between the brightening layer (3) and the second layer and is partially hollow; the not hollow area of the first layer is at least partially exposed from the hollow area of the brightening layer (3); and the second layer is at least partially exposed from the hollow areas of the brightening layer (3) and the first layer. In addition, the invention also provides a method for manufacturing the anti-fake film.

Description

technical field [0001] The application relates to an anti-counterfeiting film and a manufacturing method thereof. Background technique [0002] Holographic anti-counterfeiting technology products such as security thread, holographic label, and anti-counterfeiting strip have been used on banknotes for many years. The overall technology is mature and reliable. However, due to the high degree of marketization of this technology and easy imitation, it is not suitable for high-end anti-counterfeiting field alone. requirements. However, optical variable anti-counterfeiting technology including interference optical variable, diffractive optical variable, liquid crystal optical variable and other optical variable realization methods has a remarkable anti-counterfeiting effect due to its high technical content and difficulty in counterfeiting. Therefore, when the combination of holographic anti-counterfeiting technology and optical variable anti-counterfeiting technology is applied,...
