Title (EN) BLACK MATRIX FOR COLOUR FILTERS
(FR) MATRICE NOIRE POUR FILTRES COLORÉS
Abstract:
(EN) Actinically modifiable composition comprising, all based on the entire composition, • 10 - 70% by weight of a colorant or a mixture of colorants; • 90 - 30% by weight of actinically reactive binder material consisting of components selected from the group consisting of binders, binder precursors, dispersants, photoinitiators and stabilizers, although optionally from 0% to 30% by weight of the actinically reactive binder material can be non-reactive components; and • 0 - 10% by weight of further, non-reactive constituents; characterized in that • the composition has an optical density ≥ 1.0, preferably ≥ 1.2 and more preferably ≥ 1.4 in the entire wavelength range 430 - 650 nm per 1 μm layer thickness; and • the colorant or 50 - 100% by weight, preferably 60 - 100% by weight and more preferably 70 - 100% by weight of the colorant mixture comprises a colorant obtainable by reaction of a compound of the formula (i) with a compound of the formula (ii) in a molar ratio of 1:2, in the presence of a catalyst having a pK value ≤ 4.5 in water at 25°C, or a mixture of such colorants, wherein the black colorant is likely a product of the formula (iii) or a tautomer or isomer thereof. Likewise claimed are the use of this composition for producing colour filters, colour filters themselves and also a process for producing colour filters.
(FR) La présente invention concerne une composition modifiable sous rayonnement actinique qui comprend, par rapport à la totalité de la composition, 10-70 % en poids d'un colorant ou d'un mélange de colorants, 90-30 % en poids d'un matériau liant réactif sous rayonnement actinique constitué de composants choisis parmi les liants, les précurseurs de liants, les dispersants, les photoinitiateurs et les stabilisants, 0-30 % en poids de ce matériau liant pouvant éventuellement correspondre à des composants non réactifs, et 0-10 % en poids d'autres constituants non réactifs. La composition a une densité optique ≥ 1,0, de préférence ≥ 1,2, mieux ≥ 1,4 dans la totalité de la gamme de longueurs d'onde de 430 à 650 nm pour une épaisseur de couche de 1 µm. Le colorant ou 50-100 % en poids, de préférence 60-100 % en poids, mieux 70-100 % en poids du mélange de colorants comprennent un colorant qui peut être obtenu en faisant réagir un composé de formule (i) avec un composé de formule (ii) dans un rapport molaire de 1 : 2 en présence d'un catalyseur de pK ≤ 4,5 dans de l'eau à 25 °C, ou un mélange de tels colorants, le colorant noir étant un produit de formule (iii) ou un tautomère ou isomère de celui-ci. L'invention concerne également l'utilisation de cette composition pour la fabrication de filtres colorés, les filtres colorés eux-mêmes et un procédé de fabrication de filtres colorés.
