Problems solved by technology

However, this kind of anti-counterfeiting technology needs to show certain anti-counterfeiting features through the action of light, heat, chemical reagents, special instruments, etc., and relies too much on raw materials and special instruments, which makes the cost of this type of anti-counterfeiting carbonless copy paper high. Anti-counterfeit raw materials are easy to imitate

Embodiment Construction

[0019] The present invention will be described in further detail below in combination with specific embodiments.

[0020] An anti-counterfeiting carbonless copy paper of the present invention comprises base paper, a coating of carbonless copying paper and an anti-counterfeiting coating layer expressing information in the form of invisible graphics and texts. The coating layer includes color-developing materials, adhesives and auxiliary agents, and the invisible graphic is to process the anti-counterfeiting coating layer on the base paper or carbonless copy paper coating in a specific shape through coating.

[0021] In this embodiment, the proportion of the anti-counterfeiting paint layer is: 30-80 parts of color-developing material, 5-15 parts of adhesive, and 1-5 parts of auxiliary agent. For example see the table below:

[0022]

[0023] In this embodiment, the color-developing material is activated clay, p-aryl phenol resin, zinc salicylate or zinc salt modified phenoli...

Abstract

The invention belongs to the technical field of carbonless copy paper processing. The anti-fake carbonless copy paper is prepared by scraping or scratching back and forth within a small area with hard materials such as fingernails and plastic cards which are common in life instead of special conditions and tools to show patterns, characters, symbols or lines with different colors so as to achieve the anti-fake purpose of simple identification and common identification. The anti-fake carbonless copy paper comprises body paper, a carbonless copy paper coating and an anti-fake coating layer expressing information with invisible images and texts, wherein the carbonless copy paper coating contains a microcapsule with different colors; the anti-fake coating layer comprises a developing material, an adhesive and an auxiliary; the invisible images and texts are formed by coating the anti-fake coating layer on the body paper or the carbonless copy paper coating according to a special shape. The invention also provides a preparation method of the anti-fake carbonless copy paper.

Description

technical field [0001] The invention relates to the technical field of carbonless copy paper processing, and more specifically, to an anti-counterfeit carbonless copy paper and a preparation method thereof. Background technique [0002] In the prior art, carbonless copy paper with anti-counterfeiting function is widely used in bills, vouchers and the like. In order to ensure the normal operation of our country's economy and crack down on bill counterfeiting criminal activities in this field, the contest between anti-counterfeiting and counterfeiting is constantly escalating, and it is imperative for manufacturers to continuously introduce new bill anti-counterfeiting technologies. With the development of society and the advancement of science and technology, the single anti-counterfeiting technologies such as watermark, color fiber, temperature change, and light change used in carbonless copy paper used in bills (such as tax bills) can no longer meet the requirements of curr...
