Novel high-performance water-based fluorescent ink

Abstract

The invention relates to fluorescent ink. The fluorescent ink contains a fluorescent agent and can produce a fluorescent effect when encountering ultraviolet rays (sunlight, fluorescent lamps and mercury lamps are more frequent) and emit white light, so that the color looks like the color has a glare fluorescent feeling. The formula comprises the following components: 5-12% of dichlorofluorescein, 5-7% of sodium hydroxide, 3-5% of sodium carbonate, 2% of phosphoric acid, 2% of balance modifier, 5-8% of ethanol, 3% of fluorescent effect, not less than 70% of distilled water and 1% of additives.

Description

technical field [0001] The novel high-performance water-based fluorescent ink of the invention belongs to the field of chemical industry. [0002] The principle and characteristics of fluorescent ink The key principle of ultraviolet fluorescent ink is to add visible fluorescent (complex) compounds with ultraviolet excitation to the ink. [0003] Through the absorbed light energy, the energy level transition of atoms is generated, and then the absorbed additional energy is released. The anti-counterfeiting feature is to emit red, yellow, green and blue (400nm-800nm) visible light under the irradiation of ultraviolet light (200nm-400nm). [0004] This ink can be divided into colored and colorless, long wave (365nm) and short wave (254nm). Fluorescent pigments are organic complexes, finely ground, high luminous rate, usually colorless or light white (200nm ~ 400nm) irradiation, it will show various colors of visible light (400nm ~ 800nm). According to the wavelength of the exc...
