Abstract
(EN) This optical filter 1a is provided with a light-absorbing layer 10. The light-absorbing layer 10 is formed of a cured product of a light-absorbing composition in which a light absorber formed of a phosphonic acid and copper ions represented by formula (a) is dispersed. The optical filter 1a has an average spectral transmittance of 80% or more at a wavelength of 450-600 nm; (II) has a spectral transmittance of 1% or less at a wavelength of 750-900 nm; and (III) has an average spectral transmittance of 4% or less in a wavelength range of 350-370 nm. (IV) An infrared-side cutoff wavelength for light that is incident at an incident angle of 0° is 620-680 nm, and (V) an ultraviolet-side cutoff wavelength for light that is incident at an incident angle of 0° is 380-420 nm.
(FR) Ce filtre optique 1a est pourvu d'une couche d'absorption de lumière 10. La couche d'absorption de lumière 10 est constituée d'un produit durci d'une composition d'absorption de lumière dans laquelle est dispersé un absorbeur de lumière constitué d'un acide phosphonique et d'ions de cuivre représenté par la formule (a). Le filtre optique 1a a un facteur spectral de transmission moyen supérieur ou égal à 80 % à une longueur d'onde de 450 à 600 nm ; (II) a un facteur spectral de transmission inférieur ou égal à 1 % à une longueur d'onde de 750 à 900 nm ; et (III) a un facteur spectral de transmission moyen inférieur ou égal à 4 % dans une plage de longueur d'onde de 350 à 370 nm. (IV) Une longueur d'onde de coupure côté infrarouge pour la lumière qui est incidente à un angle d'incidence de 0° est de 620 à 680 nm, et (V) une longueur d'onde de coupure côté ultraviolet pour la lumière qui est incidente à un angle d'incidence de 0° est de 380 à 420 nm.
(JA) 光学フィルタ1aは、光吸収層10を備える。光吸収層10は、下記式(a)で表されるホスホン酸と銅イオンとによって形成された光吸収剤が分散している光吸収性組成物の硬化物によって形成されている。光学フィルタ1aは、波長450nm~600nmにおいて80%以上の平均分光透過率を有し、(II)波長750nm~900nmにおいて1%以下の分光透過率を有し、(III)波長350nm~370nmの範囲において4%以下の平均分光透過率を有する。(IV)0°の入射角で入射する光に対する赤外側カットオフ波長が620nm~680nmであり、(V)0°の入射角で入射する光に対する紫外側カットオフ波長が380nm~420nmである。
