Abstract
The invention discloses green and environment-friendly water-soluble fluorescent ink which is prepared from kitchen garbage such as fruit peels and vegetable bits and the like serving as raw materials by a microwave oven or an oven at a high temperature, and is safe, green, environment-friendly and pollution-free. The green environment-friendly water-soluble fluorescent ink also has a fluorescent invisible anti-counterfeiting function.
Description
Technical Field
The invention belongs to the field of fluorescence anti-counterfeiting, and particularly relates to green environment-friendly water-soluble invisible anti-counterfeiting fluorescent ink and related application thereof.
Background
Fluorescence is a common phenomenon in nature. When a normal temperature substance is irradiated by incident light (usually ultraviolet) with a certain wavelength, the light energy is absorbed and enters an excited state, then the excited state is de-excited and the time is very short (10) -8 Second) transmissionVisible light with various colors and different intensities (usually, the wavelength is in the visible light region and is longer than the wavelength of incident light), and when the ultraviolet light stops irradiating, the light-emitting phenomenon also disappears immediately. Light with this property is fluorescence [1 ]]. The fluorescence characteristics of substances are related to various factors, and the fluorescence phenomenon is widely applied to various fields.
The criminal cases such as forged documents, critics, bills and the like are in a high trend, and the forging criminal behaviors seriously damage the good trust of the social public on the state organs, further damage the normal public management activities of the state organs and seriously threaten the state safety and the property safety of people. Therefore, the research on a novel environment-friendly anti-counterfeiting technology is of great significance.
There are many security technologies, and those related to fluorescence are paper and printing inks. Fluorescent ink technology is mature at present and is one of the most important means for printing banknotes. Now, the abuse of fluorescent agents causes environmental pollution. Therefore, the development of the green environment-friendly water-soluble invisible anti-counterfeiting fluorescent ink has extremely important significance.
