  • the composition of the present invention has excellent storage stability. By using the composition of the present invention, it is possible to form a film having excellent spectral characteristics and excellent light resistance and humidity resistance. Although the detailed reason why such an effect is obtained is unknown, it is presumed to be due to the following.
  • the two rings directly connected to the squaric acid moiety are -NH-Y 1 -CRa 1 Rb 1 -X 1 -CRa 2 Rb 2 It has a structure linked by -Y 2 -NH-. where Ra 1 and Ra 2 are electron withdrawing groups.
  • the dye represented by formula (1) has such a structure improves the stability of the chromosomal nucleus against nucleophilic attack by nucleophilic compounds, water, and the like. Furthermore, since Ra 1 and Ra 2 are electron-withdrawing groups, the solubility in solvents is increased. For this reason, it is presumed that the decomposition, denaturation, aggregation, etc. of the dye represented by formula (1) during storage of the composition could be suppressed, and a composition excellent in storage stability could be obtained. In addition, since the composition has excellent storage stability, it is possible to form a film in which defects are suppressed even when the composition is used after storage.
  • the dye represented by the formula (1) since the dye represented by the formula (1) has high stability of the dye mother nucleus against nucleophilic attack by nucleophilic compounds and water, the use of the composition of the present invention improves light resistance and moisture resistance. A film having excellent properties can be formed. Further, in the dye represented by formula (1), Ra 1 and Ra 2 are electron-withdrawing groups, so that the oscillator strength of absorption in the visible region is reduced, or the absorption in the visible region is shortened. It is presumed that by doing so, the visible transparency of the pigment could be further improved. Therefore, by using the composition of the present invention, a film having excellent spectral characteristics can be formed.
  • the composition of the present invention can be used as a composition for optical filters.
  • Types of optical filters include infrared cut filters and infrared transmission filters. Since the dye represented by the formula (1) has excellent visible transparency, an infrared cut filter having excellent visible transparency can be formed by using the composition of the present invention. Further, in the infrared transmission filter, the dye represented by the formula (1) has a role of limiting transmitted light (infrared rays) to a longer wavelength side. Since the dye represented by the formula (1) is excellent in visible transparency, it is easy to control the spectrum in the visible region to be shielded and the spectrum in the infrared region to be transmitted within an appropriate range.
