Abstract

Provided is a near-infrared absorptive coloring matter that enables the production of a near-infrared blocking filter having excellent transparency, heat resistance and moist heat resistance. The near-infrared absorptive coloring matter is characterized by consisting of a noncrystalline body of a diimonium salt represented by general formula (1).

Description

technical field [0001] The present invention relates to a near-infrared-absorbing dye formed of an amorphous diimonium salt, a near-infrared-absorbing adhesive composition using the near-infrared-absorbing dye, and a resin composition for a near-infrared-absorbing hard coat layer. More specifically, The present invention relates to a near-infrared absorbing composition having excellent transparency in the visible light region and a near-infrared absorbing effect, as well as high heat resistance and moisture resistance, and a near-infrared shielding filter using the near-infrared absorbing composition. Background technique [0002] In recent years, plasma display panels (abbreviated as "PDPs" hereinafter) have been widely popularized as the demand for larger and thinner displays increases. Near-infrared rays are emitted from the PDP, which can cause malfunctions in electronic devices using near-infrared remote controls. Therefore, it is necessary to use a filter containing a ...
