Title (EN) PIGMENT COMPOSITION FOR COLOR FILTERS, AND COLOR FILTER
(FR) COMPOSITION DE PIGMENTS POUR FILTRES COLORÉS, ET FILTRE COLORÉ
(JA) カラーフィルタ用顔料組成物及びカラーフィルタ
Abstract:
(EN) Provided are: a novel pigment composition for color filters, which is capable of forming a color filter having high luminance; and a color filter which contains this pigment composition for color filters. This pigment composition for color filters contains a green pigment that has such spectral characteristics that the transmittance at the wavelength of 555 nm is 45% or more, the ratio of the transmittance at the wavelength of 505 nm to the transmittance at the wavelength of 555 nm, namely T(505 nm)/T(555 nm) is 1.40 or more, and the half-value width is 80 nm or less, if formed into a coating film wherein the spectral transmittance at the maximum transmission wavelength is 80%. A color filter according to the present invention contains this pigment composition for color filters.
(FR) La présente invention concerne : une nouvelle composition de pigments pour filtres colorés, qui est capable de former un filtre coloré ayant une forte luminance ; et un filtre coloré qui contient cette composition de pigments pour filtres colorés. Cette composition de pigments pour filtres colorés contient un pigment vert qui présente des caractéristiques spectrales de telle sorte que la transmittance à la longueur d’onde de 555 nm est 45 % ou plus, le rapport de la transmittance à la longueur d’onde de 505 nm sur la transmittance à la longueur d’onde de 555 nm, à savoir T(505 nm)/T(555 nm) est 1,40 ou plus et la largeur à demi-valeur est 80 nm ou moins, si elle est formée dans un film de revêtement dans lequel la transmittance spectrale à la longueur d’onde de transmission maximale est de 80 %. Un filtre coloré selon la présente invention contient cette composition de pigments pour filtres colorés.
(JA) 高輝度のカラーフィルタを作製可能な新規のカラーフィルタ用顔料組成物及び前記カラーフィルタ用顔料組成物を含有するカラーフィルタを提供する。カラーフィルタ用顔料組成物は、極大透過波長における分光透過率が80%になるように塗膜を形成した際に、波長555nmの透過率が45%以上であり、波長505nmの透過率と波長555nmの透過率の比(T(505nm)/T(555nm))が1.40以上であり、半値幅が80nm以下となる分光特性を有する緑色顔料を含有する。カラーフィルタは、前記カラーフィルタ用顔料組成物を含有する。
