Anti-counterfeiting infrared excitation technology: the near-infrared absorbing material is added into the ink;

The one or more near-infrared absorbing materials are added to the ink, and the near-infrared absorbing material is an organic functional dye. It has absorption in the near-infrared region and has a maximum absorption wavelength of 700 nm to 1100 nm.

Our plan

    • Infrared excitation technology ink

      The one or more near-infrared absorbing materials are prepared by adding to the ink, and the near-infrared absorbing material is an organic functional dye;

    • Range of action

      It has absorption in the near-infrared region, the maximum absorption wavelength is 700nm～1100nm, and the oscillation wavelength falls in the near-infrared region. Since the near-infrared absorption ink absorbs infrared rays, there is no trace under sunlight, but under the detection instrument, the corresponding signal can be observed. Or dark graphics.
