Description

The present invention relates to a colored composition containing a near-infrared absorbing compound.

Video cameras, digital cameras, smartphones, and the like use CCDs (charge-coupled devices) and CMOSs (complementary metal oxide semiconductors), which are solid-state imaging devices for color images. Since the light-receiving part of these solid-state image sensors uses silicon photodiodes that are sensitive to infrared rays, it is necessary to perform visibility correction, and they have a two-layer structure that uses a color filter and an infrared cut filter. .

In recent years, from the viewpoint of thinning solid-state image sensors, studies have been made to make the infrared cut filter thinner or to eliminate the infrared cut filter.

For example, Patent Document 1 discloses a red colored composition for a color filter containing a red colorant, a near-infrared absorber, and a polymerizable compound. Further, Patent Document 2 discloses a green coloring composition for a color filter containing a green colorant, a near-infrared absorber, and a polymerizable compound.

General formula (1)

In general formula (1), X ₁ to X ₈ and Y ₁ to Y ₈ each independently represent a hydrogen atom, a halogen atom, a nitro group, a sulfone group, an alkyl group that may have a substituent, or a substituent. Aryl group that may have a substituent, cycloalkyl group that may have a substituent, heterocyclic group that may have a substituent, alkoxyl group that may have a substituent, Good aryloxy group, optionally substituted alkylthio group, optionally substituted arylthio group, optionally substituted phthalimidomethyl group, or optionally substituted sulfamoyl group represents a group.
