Abstract

The invention discloses an optical variable anti-fake element for bills, credit cards, passports, securities and product packages. The optical variable anti-fake element comprises a carrier chaff, a grid element, a thin layer element and a light scattering element; the grid element comprises a first grid element and a second grid element; the first grid element and the second grid element are arranged on two sides of the light scattering element; the light scattering element is formed by screen printing of light scattering particles on the second grid element; and the lower surface of the light scattering layer is not a plane, and is arranged as a shape corresponding to a gap of the second grid element to fill the gap of the second grid element. The optical variable anti-fake element achieves different pattern effects during transmitting in different directions to further improve the anti-fake performance.

Description

technical field [0001] The invention relates to an optically variable anti-counterfeit element and a financial anti-counterfeit bill with the optically variable anti-counterfeit element. Background technique [0002] While high-tech promotes social progress and promotes rapid economic development, there are also increasing cases of fraudulent use of high-tech to forge various documents, credit cards, and large-value bills, causing great economic losses to the country and individuals, and serious social impact. In order to reduce financial risks, anti-counterfeiting requirements for high-security products such as banknotes, credit cards, and securities are getting higher and higher, and countries have increased investment in anti-counterfeiting technology and equipment research and development. [0003] Optical anti-counterfeiting refers to the use of the basic principles of light waves such as light reflection, transmission, refraction, interference, diffraction, polarizati...
