Near Infrared (NIR) Dyes
Near infrared dyes show light absorption in the near infrared area of 700-2000 nm. Their intense absorption normally originates from a charge transfer of an organic dye or metal complex.

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.

Photochromic pigment Sun Sensitive Pigment
Photochromic pigments change from one color to another and colorless to color when exposed to sunlight or ultraviolet (UV) light, and reverts to its original color when sunlight is blocked. After absorbing the energy of sunlight or UV light, it’s molecule structure is changed, which caused its absorbed wavelength to be changed allowing a color to appear.
-
Sunlight Sensitive Pigment
Photochromic pigments change color when exposed to UV light or sunlight. Once removed from the UV light or sunlight, the pigment fades back to its normal color after a minute or so.
-
Sun Sensitive Color Changing Photochromic Pigment
Photochromic pigment is a specialty designed powder to change color when exposed to a UV light source, but reacts best to direct sunlight. White or colorless when not exposed to sunlight.
