NIR absorbing dyes is more often used for safty consideration. It can absorb certain wavelength of the IR lights.
Infrared Invisible Pigment (980nm) also called 980nm up-Conversion Infrared Pigment，It is white color powder form while under infrared ray,it will show color. when move away from infrared ray, it will back to white color;
The UV reactive fluorescent pigment is a special pigment that is very sensible to the exposure at short-range UV wich is also known as ”black light.
UV reactive fluorescent pigment lights up intensively under UV light.
Near Infrared Absorbing Dye from ,710nm, 750nm, 780nm, 790nm, 800nm, 815nm, 817nm, 820nm, 830nm,850nm, 880nm, 910nm, 920nm,932nm, 980nm, 1001nm,1064nm, 1070nm , 1082nm
Near infrared absorption dye, absorption wavelength between 710nm-1070nm
Photochromic Dyes are reversible raw dyes in crystalline powder form.Full color change occurs in just seconds when using a flash gun to 20-60 seconds in the sunlight.
Near-infrared (also called near-IR or NIR) dyes offer important advantages over traditional visible light 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.
980nm IR fluorescent pigment : Infrared excitation ink is a printing ink giving off visible, bright and dazzling light (red, green and blue) when exposed to infrared light (940-1060nm). With the features of high technology content, difficulty in copying and high anti-forgery capability, it can be applied in anti-forgery printing widely, especially in banknotes and gasoline vouchers.
infrared invisible pigment (980nm)
A kind of rare earth, with no radioactive component.
After absorbing visual light, sunlight, lamp light, UV light etc, it can store the energy and give off light in dark. This process can be repeated for ever
Infrared excitation ink/pigment: Infrared excitation ink is a printing ink giving off visible, bright and dazzling light (yellow，red, green and blue) when exposed to infrared light (940-1060nm). With the features of high technology content, difficulty in copying and high anti-forgery capability, it can be applied in anti-forgery printing widely, especially in RMB notes and gasoline vouchers.
Microencapsulated UV coloring material, after the sun / ultraviolet radiation, resulting in color display and disappear, with the color fast, no residual color, good weather resistance, etc.
