Near-infrared Light Absorption Materials
Yamada Chemical has developed near-infrared light absorbing materials including functional phthalocyanine and naphthalocyanine.
In addition to selective absorption in the near-infrared region (750-1000nm), these materials achieve high transparency unique to organic dyes.
In addition to high durability (high light resistance, high heat resistance) and high transparency, it also has excellent solubility in various solvents, making it easier to process into resins.
These materials are attracting attention as key materials for heat ray shielding (heat shielding) materials, anti-counterfeiting inks, and various sensors.
Areas of Use
Various filter applications, various sensor applications, laser welding, heat ray shielding applications, various ink applications, etc.
