Abstract

The invention discloses a piece of temperature dependent reversible tenebrescence anti-counterfeiting paper which is made of fiber raw materials and auxiliary materials. The fiber raw materials are composed of 20-100% of broad-leaf full bleaching chemical wood pulp and 0-80% of needle-point-leaf full bleaching chemical wood pulp. The auxiliary materials contain 2-4% of modified temperature dependent reversible tenebrescence materials, 0.8-1.4% of cationic starch, 15-25% of stuffing, 0.2-0.5% of sizing agents and 0.02-0.04% of retention aids. The temperature dependent reversible tenebrescence materials are organic combinations of crystallization inner ester, phenols and fluorescent materials. Chitosan and surface active auxiliaries such as lauryl sodium sulfate and polysorbate are added into the temperature dependent reversible tenebrescence materials, and hydrophily and dispersed suspension performance of the materials in water are adjusted. The suspension state of fibers in water after the fibers adsorb the temperature dependent reversible tenebrescence materials is adjusted through surface active agents, and fiber interweaving uniformity and water filter moldability are improved.

Description

technical field [0001] The invention relates to an anti-counterfeit paper, in particular to a temperature-induced reversible fluorescent anti-counterfeit paper and a manufacturing method thereof, belonging to the technical field of anti-counterfeit paper manufacture. Background technique [0002] With the development of society and the advancement of technology, the demand for paper printed matter is increasing, and at the same time, the competition in the commodity market is becoming increasingly fierce. Some criminals use paper or packaging cardboard without anti-counterfeiting marks to mass-produce counterfeit or pirated products to make huge profits. Great damage to the interests of enterprises or publishers. In order to put an end to the living environment of counterfeit or pirated products, various companies and publishers have adopted anti-counterfeiting marks to protect their legitimate rights and interests, such as affixing anti-counterfeiting labels on product cove...
