Problems solved by technology

[0003] The existing anti-counterfeiting inks all use a near-infrared absorption anti-counterfeiting material. Therefore, the ink has only one absorption peak under the infrared spectrum, and the anti-counterfeiting effect is not strong enough, and it is easy to imitate

Abstract

The invention discloses an infrared absorption anti-fake ink which comprises the following raw materials in parts by weight: 10-20 parts of an infrared absorption material A, 10-20 parts of an infrared absorption material B, 12-24 parts of a connecting material, 15-20 parts of a pigment, 30-40 parts of a synthetic resin, 6-8 parts of plant oil, 2-4 parts of mineral oil, 16-20 parts of a filler, 2-4 parts of a composite drying agent, 30-40 parts of a solvent and 0.3-0.5 part of an anti-caking agent, wherein the maximum absorption peak of the infrared absorption material A is within 700-900nm; the maximum absorption peak of the infrared absorption material B is within 950-1250nm; the infrared absorption material A or the infrared absorption material B comprises copper ions, phosphate radicals and carbonate; and the position of the maximum absorption peak is determined by contents of the copper ions, the phosphate radicals and the carbonate in the infrared absorption materials. The infrared absorption anti-fake ink is not easy to imitate and convenient in anti-fake characteristic detection, is approximately colorless, is applicable to various tickets, notes, trademarks and similar articles, can be adopted to print various hidden bar codes which are invisible by naked eyes, is good in concealing, and is capable of effectively preventing copy and imitation.

Description

technical field [0001] The invention belongs to the technical field of anti-counterfeiting printing, and in particular relates to an infrared-absorbing anti-counterfeiting ink. Background technique [0002] Anti-counterfeiting ink is a kind of anti-counterfeiting product with a very wide range of applications, especially in the printing of banknotes, valuable notes and other products. Negotiable securities, bills, and famous and high-quality trademarks are often forged, altered, and altered by criminals, which has become a major public hazard today. [0003] Existing anti-counterfeiting inks all use a near-infrared absorption anti-counterfeiting material. Therefore, the ink has only one absorption peak under the infrared spectrum, and the anti-counterfeiting effect is not strong enough and is easy to imitate. With the improvement of social science and technology, criminals are becoming more and more rampant, and it is imperative to strengthen the technical content of anti-c...
