Are fluorescent pigments poisonous?
The pigment does not contain any radioactive elements and toxic heavy metals, so non-toxic, harmless, safe for the human body, is a new generation of green fluorescent pigments.
Fluorescent pigments are organic complexes that are finely ground and have high luminous rates, usually colorless or light white. They exhibit visible light (400nm ~ 800nm) in various colors under ultraviolet light (200nm ~ 400nm). According to the wavelength of the excitation light source, can be divided into short-wave ultraviolet excitation fluorescent pigment (excitation wavelength of 254nm) and long-wave ultraviolet excitation pigment (excitation wavelength of 365nm).
Fluorescent pigments are functional luminous pigments, and the difference between the general pigment is that when the external light (including ultraviolet light) irradiation, can absorb a certain form of energy, and excited photons, in the form of low visible light to absorb the energy released, resulting in different Hue fluorescence phenomenon. Different shades of light to form an exceptionally bright color, and when the light stops illuminating, the luminous phenomenon disappears, so called fluorescent pigments. Fluorescent pigment and polymer resin connector, solvent and additives ratio, the grinding can be made fluorescent ink.
