Problems solved by technology

[0003] However, materials with high infrared reflection are often monochromatic pigments, which can only be used to identify the authenticity of anti-counterfeiting components on specific identification instruments
Magnetic and infrared double anti-counterfeiting can only be printed with two different inks at present, and cannot be used in combination directly

Abstract

The invention discloses an anti-counterfeiting pigment composition and a preparation method thereof. The anti-counterfeiting pigment composition comprises a pigment with an anti-counterfeiting characteristic and an infrared reflection pigment, the mass ratio of the pigment with the anti-counterfeiting characteristic is 10%-80%, the mass ratio of the infrared reflection pigment is 20%-90%, the transmittance of the infrared reflection pigment to a visible light wave band is larger than 90%, and the reflectivity of the infrared reflection pigment to an infrared wave band with the interval of 780-1200 nm is larger than 85%. The anti-counterfeiting pigment composition provided by the invention is a combination of the pigment with anti-counterfeiting characteristics and the infrared reflection pigment, has multiple anti-counterfeiting effects, and is good in color contrast property and high in color uniformity.

Description

technical field [0001] The present application relates to the technical field of optical anti-counterfeiting, in particular to an anti-counterfeiting pigment composition and a preparation method thereof. Background technique [0002] In recent years, with the development of anti-counterfeiting technology, a variety of color-changing and special synthetic materials have gradually emerged. Color-changing materials are widely used in traditional visual anti-counterfeiting technology, and more and more invisible anti-counterfeiting technologies are added to color-changing materials, such as infrared anti-counterfeiting and magnetic anti-counterfeiting. [0003] However, the infrared high-reflection materials are often monochromatic pigments, and the authenticity of the anti-counterfeiting element can only be identified on a specific identification instrument. Magnetic and infrared dual anti-counterfeiting can only be printed by two different inks at present, and cannot be used ...
