Abstract

The invention provides multi-response fluorescent ink and a preparation method. The multi-response fluorescent ink comprises, by weight, 0.5-5 parts of rare earth metal salt, 1-5 parts of organic ligands, 50-70 parts of organic solvents, 20-30 parts of polymer resin and 0.1-2 parts of auxiliaries, wherein the rare earth metal salt is selected from one or two of europium salt and terbium salt, theorganic ligands are beta-diketone molecules, the polymer resin is selected from one or more of acrylic resin, epoxy resin, ethylene resin and polyurethane, and the auxiliaries are selected from dryingcatalysts, diluents, viscosity reducers, thinners, antioxidants, anti-gelling agents, defoaming agents, surfactants, anti-pitting agents, slipping agents and plasticizers. The fluorescent ink presents different fluorescent colors under the ultraviolet condition of different wavelengths, can present multicolor fluorescence after being stimulated by different substances, and has the advantages of high anti-counterfeiting level and strong anti-counterfeiting capacity.

Description

technical field [0001] The invention relates to a fluorescent ink and a preparation method, in particular to a multi-response fluorescent ink and a preparation method. Background technique [0002] Fluorescent ink is one of the most important branches of anti-counterfeiting ink, and it is also the ivy in the field of anti-counterfeiting ink technology. Existing fluorescent inks on the market can be divided into three categories according to the excitation light: ultraviolet excitation, infrared excitation and visible light excitation. The main radiation, this technology is quite mature, and the anti-counterfeiting level is relatively low. The market needs new fluorescent ink products with high anti-counterfeiting strength, but there are relatively few products and technologies in this area. Contents of the invention [0003] The invention provides a multi-response fluorescent ink and a preparation method to at least solve the problem of low anti-counterfeiting level of t...
