Abstract

The invention discloses a vegetable oil-based fluorescent anti-counterfeiting ink, and a preparation method and an application thereof. The vegetable oil-based fluorescent anti-counterfeiting ink is prepared from, by mass, 70-80% of a vegetable oil binder, 10-20% of a fluorescent pigment, 3-5% of a fluorescent whitening agent, 1-3% of a vegetable ink drying agent, 1-3% of a defoaming agent and 1-2% of a hyperdispersant, wherein the vegetable oil binder comprises 30-40% of soybean oil, 10-20% of tung oil, 40-50% of rosin modified phenolic resin and 1-2% of an antioxidant. The vegetable oil-based fluorescent anti-counterfeiting ink prepared in the invention has a good environmental protection performance and a high luminous intensity, has a beautiful fluorescent color effect, good resistanceand good fixing performance after being printed, is suitable for various printing modes, and can be applied to the counterfeiting resistance of product packaging and tickets.

Description

technical field [0001] The invention belongs to the technical field of anti-counterfeiting inks, and in particular relates to a vegetable oil-based fluorescent anti-counterfeiting ink and its preparation method and application. Background technique [0002] Fluorescent anti-counterfeiting ink, as a kind of ink anti-counterfeiting technology, is favored by consumers in the printing market and more and more people in the printing industry due to its advantages such as good color rendering performance, high concealment, convenient identification, fine background color, and high reliability. , is widely used in packaging printing and anti-counterfeiting printing fields. Fluorescent ink is made by adding corresponding visible fluorescent compounds to the ink. When external light (including ultraviolet light) is irradiated, the fluorescent pigment can absorb a certain form of energy, and excite photons to release the absorbed energy in the form of low visible light. come out, res...
