Compositions, hardened materials, optical components, light source units, displays, lighting devices, and compounds

Abstract

The objective of this invention is to improve both color reproduction and durability in compositions or optical components used in light source units, displays, or lighting devices, particularly by achieving both high color purity emission or selective light absorption within a narrow wavelength range and high durability at high temperatures. A composition comprising the following components (A), (B), and (C): (A) an organic pigment compound; (B) at least one of a compound comprising two or more dihydroxyboron groups or derivatives thereof, and boric acid or derivatives thereof; (C) a sugar alcohol or derivative thereof; wherein components (B) and (C) have a molar absorptivity ε of 100 or less across the entire wavelength range of 400 nm to 800 nm; furthermore, the organic pigment compound has at least one substituent represented by general formulas (1A) to (1C). (In general formulas (1B) and (1C), the carbon atoms in the methylene and methylene groups may be independently substituted with alkyl groups.)
