Document Type and Number:
Japanese Patent JP7099251
Kind Code:
B2
Abstract:
To provide a near-infrared absorbing composition excellent in near-infrared cut stability and dispersion stability of constituent material over time, a near-infrared absorbing film formed using the same, an image sensor for a solid-state imaging element comprising the near-infrared absorbing film.SOLUTION: The near-infrared absorbing composition contains a near-infrared absorbent and a solvent. The near-infrared absorbent includes a copper complex 1 comprising copper ions and a phosphate having a structure represented by the specified general formula (I), and a copper complex 2 comprising copper ions and a phosphate having a structure represented by the specified general formula (II).SELECTED DRAWING: Figure 1
