Abstract:
(EN) Provided is a near-infrared absorbing dye having transparency to visible light and near-infrared blocking characteristics in which the transmittance is increased for light having wavelengths of 430-550 nm in particular. Absorption characteristics of the near-infrared absorbing dye, which are measured by dissolving the dye in dichloromethane, satisfy the following requirements: ・In an absorption spectrum at wavelengths of 400-800 nm, a maximum absorption wavelength λmax exists in the wavelength region of 670 nm or higher; ・Relational expression εBA ≥ 65 holds between a maximum absorption coefficient εA for light having wavelengths of 430-550 nm and a maximum absorption coefficient εB of light having wavelengths of 670 nm or higher; and ・In a spectral transmittance curve, the average transmittance of light having wavelengths of 430-460 nm is equal to or greater than 94.0 % when the transmittance at the maximum absorption wavelength λmax is assumed to be 1 %.
(FR) L'invention concerne un colorant absorbant dans le proche infrarouge, qui est transparent à la lumière visible et présente des caractéristiques de blocage du proche infrarouge dans lesquelles la transmittance est augmentée pour une lumière ayant des longueurs d'onde de 430 à 550 nm en particulier. Les caractéristiques d'absorption du colorant absorbant dans le proche infrarouge, qui sont mesurées par dissolution du colorant dans du dichlorométhane, satisfont les exigences suivantes: dans un spectre d'absorption à des longueurs d'onde de 400 à 800 nm, une longueur d'onde d'absorption maximale λmax existe dans la région de longueur d'onde de 670 nm ou plus; l'expression relationnelle εB/εA ≥ 65 vaut entre un coefficient d'absorption maximale εA d'une lumière ayant des longueurs d'onde de 430 à 550 nm et un coefficient d'absorption maximale εB d'une lumière ayant des longueurs d'onde de 670 nm ou plus; et dans une courbe de transmittance spectrale, la transmittance moyenne d'une lumière ayant des longueurs d'onde de 430 à 460 nm est égale ou supérieure à 94,0% lorsque la transmittance, à la longueur d'onde d'absorption maximale λmax, est supposée être de 1%.
(JA) 可視光の透過性、とくに波長430~550nmの光の透過率を高めた近赤外線遮蔽特性を有する近赤外線吸収色素を提供する。 近赤外線吸収色素は、ジクロロメタンに溶解して測定される吸収特性が下記要件を満たす。 ・波長400~800nmの吸収スペクトルにおいて、670nm以上の波長領域に最大吸収波長λmaxを有する。 ・波長430~550nmの光に対する最大吸光係数εと、波長670nm以上の光に対する最大吸光係数εとの間に、次の関係式が成り立つ。 ε/ε≧65 ・分光透過率曲線において、前記最大吸収波長λmaxにおける透過率を1%としたとき、波長430~460nmの光の平均透過率が94.0%以上である。
