uv fluorescent invisible pigment
The fluorescent pigment is invisible to the normal light, it only glows bright in the light of the blacklight lamps. For maximum effect it is recommended to use UV lamps with a wavelength of 365 nm and transparent paints.
-
invisible security pigment
invisible security pigment also called uv fluorescent pigment，Ultraviolet fluorescent Pigment.
These pigments are neutral in color, with a white to off-white powder appearance. Not noticeable when incorporated into security inks, fibres, papers. When irradiated with 365nm UV light, the pigment emits fluorescent radiation of yellow, green, orange, red, blue and violet colors and so is immediately identifiable.

UV Fluorescent Pigments for security
Topwell chemical develops and manufactures a range of organic and inorganic security pigments.
General introduction:
Under visible light, the UV Fluorescent Pigment color is white or nearly transparent. But under UV 254nm and 365nm light, the pigment show one or more fluorescent color. The main application is to prevent from counterfeiting.
It is also called UV phosphor pigment, security pigment.

UV Fluorescent Security Pigments
Topwellchem manufacture a range of organic and inorganic security pigments that are excited by both short and long wave UV light (as well as special dual excitation/emission products). Emissions span the range of visible colours and are generally intense and lightfast.

365nm organic uv fluorescent pigment for security ink
UV Fluorescent security pigment are able to absorb non-visible light in the UV‑A, UV‑B or UV‑C region and emit visible light in the whole range of the visible spectra.
Uv fluorescent pigment is colorless in visible light and glows brightly under UV lamps
-
uv fluorescent pigment for anti-falsification printing
UV fluorescent pigment itself is colorless, and after absorbing the energy of the ultraviolet light (uv-365nm or uv-254nm), it rapidly releases energy and exhibits a vivid color fluorescent effect. When the light source is removed, it stops immediately and back to the original invisible state.
