False proof particle non-carbon manifold paper CF paper and producing method thereof

Abstract

The invention belongs to the carbonless copy paper processing technology field, in particular to an anti-counterfeiting particle carbonless copy CF paper as well as the production method thereof. The anti-counterfeiting particle carbonless copy CF paper has the technical proposal that anti-counterfeiting particles are added in the CF coating of the carbonless copy paper, while colorful anti-counterfeiting particles can be clearly seen under visible light, colorless fluorescent anti-counterfeiting particles can be easily observed under ultraviolet light, and the color change of temperature-changing anti-counterfeiting particles can be observed according to the temperature changing range when the condition is satisfied. The anti-counterfeiting particles with different colors can be used by being mixed according to a certain proportion. During identification, observation can be carried out or certain instruments can be used for determining whether the anti-counterfeiting particles accord with the proportion, thereby realizing the anti-counterfeiting purpose.

Description

Anti-counterfeit particle carbonless copy paper CF paper and production method thereof technical field The invention belongs to the technical field of carbonless copy paper processing, in particular to an anti-counterfeit particle carbonless copy paper CF paper and a production method thereof. Background technique Carbonless copy paper has been widely used in tickets, vouchers, securities, labels, etc. Due to its special purpose, users and management departments often require appropriate anti-counterfeiting functions to be added to the paper to prevent criminals from forgery. Anti-counterfeiting carbonless paper products currently on the market usually add anti-counterfeiting means to the carbonless paper base paper, and then coat and process to produce carbonless copy paper with anti-counterfeiting functions, such as watermark carbonless anti-counterfeiting fiber carbonless paper, etc. Watermarking is the use of equipment with corresponding patterns and texts (such as wa...
