Problems solved by technology

With the development of science and technology, criminals are more and more capable of counterfeiting. The traditional anti-counterfeiting paper has been forged by many criminals and cannot effectively play an anti-counterfeiting role. Anti-counterfeiting paper has become a technical problem that manufacturers urgently need to solve

Embodiment 1

[0034] see figure 1 , as shown in the figure, a covert anti-counterfeiting paper includes a base material layer 1 with a visible ink layer 2 on the base material layer 1 and a covert ink layer 3 on the covert ink layer 2 . The substrate layer is coated paper layer, offset layer or bond paper layer. The hidden ink layer is a hidden logo pattern layer, and the hidden logo pattern layer is a hidden two-dimensional code layer or a hidden pattern layer. The recessive ink contains a reaction reagent capable of reacting with dilute nitric acid with a molar concentration of 30-35% to turn black, and the reaction reagent accounts for 10-20% by volume of the recessive ink. The reaction reagent is 3-cyclohexylmethylamino-6-methyl-7-anilinofluorane synthesized by reacting diphenylcopper derivatives with 2-methyl-4-methoxydiphenylamine.

Embodiment 2

[0036] see figure 2 , as shown in the figure, a covert anti-counterfeiting paper includes a base material layer 1 with a visible ink layer 2 on the base material layer 1 and a covert ink layer 3 on the covert ink layer 2 . The overt ink layer 2 also has a refraction anti-counterfeiting layer 4 printed with refraction ink. The refraction ink is UV refraction ink. The substrate layer is coated paper layer, offset layer or bond paper layer. The hidden ink layer is a hidden logo pattern layer, and the hidden logo pattern layer is a hidden two-dimensional code layer or a hidden pattern layer. The recessive ink contains a reaction reagent capable of reacting with dilute nitric acid with a molar concentration of 30-35% to turn black, and the reaction reagent accounts for 10-20% by volume of the recessive ink. The reaction reagent is 3-cyclohexylmethylamino-6-methyl-7-anilinofluorane synthesized by reacting diphenylcopper derivatives with 2-methyl-4-methoxydiphenylamine.

Embodiment 3

[0038] see image 3 , as shown in the figure, a covert anti-counterfeiting paper includes a base material layer 1 with a visible ink layer 2 on the base material layer 1 and a covert ink layer 3 on the covert ink layer 2 . There is a watermark pattern layer 5 between the substrate layer 1 and the visible ink layer 2 . The substrate layer is coated paper layer, offset layer or bond paper layer. The hidden ink layer is a hidden logo pattern layer, and the hidden logo pattern layer is a hidden two-dimensional code layer or a hidden pattern layer. The recessive ink contains a reaction reagent capable of reacting with dilute nitric acid with a molar concentration of 30-35% to turn black, and the reaction reagent accounts for 10-20% by volume of the recessive ink. The reaction reagent is 3-cyclohexylmethylamino-6-methyl-7-anilinofluorane synthesized by reacting diphenylcopper derivatives with 2-methyl-4-methoxydiphenylamine.

Abstract

The invention discloses a recessive antifalsification paper and a preparation method thereof. The recessive antifalsification paper comprises a substrate layer, wherein the substrate layer is provided with a dominant ink layer; and a recessive ink layer is arranged on the dominant ink layer. The recessive antifalsification paper prepared by the preparation method of the invention adopts the specific recessive ink layer, and can be additionally provided with a diacaustic antifalsification layer and a watermark pattern layer, so that the antifalsification measures of the antifalsification paper are effectively increased, and the antifalsification effect is improved. Different materials of the substrate are chosen to adapt to different types of antifalsification papers.

Description

technical field [0001] The invention relates to an anti-counterfeiting paper, in particular to a hidden anti-counterfeiting paper. [0002] The invention also relates to a preparation method of the concealed anti-counterfeiting paper. Background technique [0003] Anti-counterfeiting paper is a general term for special papers with marks or hidden marks (patterns, patterns, watermarks, numbers, etc.) on the surface, which are not easy to imitate, fake or change. Anti-counterfeiting is the measure taken to prevent imitation or reproduction for the purpose of deception and without the permission of the owner. Anti-counterfeiting paper can generally be used as label identification, certificate card, bill, securities and so on. With the development of science and technology, criminals are more and more capable of counterfeiting. The traditional anti-counterfeiting paper has been forged by many criminals and cannot effectively play an anti-counterfeiting role. Anti-counterfeiti...
