A quinone-based ionic compound, a method for producing the same, transparent near infrared ray shielding film containing the quinone-based ionic compound and a method for producing the same

摘要

The present invention relates to a quinoid-based ionic compound, a method for manufacturing the same, and a near-infrared blocking film comprising the quinoid-based ionic compound, wherein the quinoid-based ionic compound has high transmittance in the visible region and high absorbance in the near-infrared region. It has an efficient near infrared ray blocking, and has high solubility in an organic solvent, so that it is not only easy to manufacture into a thin film, but also has excellent affinity with a polymer, so that it can maintain high heat and high humidity characteristics for a long time in a thin film state. The near-infrared blocking film containing the quinoid-based ionic compound is suitable for application to a protective film for protecting electronic devices, and can also be used as an insulating film or a light energy absorbing layer.
