Title
(EN) COLORED RESIN COMPOSITION FOR COLOR FILTERS
(FR) COMPOSITION DE RÉSINE COLORÉE POUR DES FILTRES COLORÉS
(JA) カラーフィルター用着色樹脂組成物
Abstract
(EN)
The present invention pertains to: a colored resin composition for color filters which comprises (i) a coloring material consisting of a specific acid dye containing a xanthene skeleton or a specific dye containing a triarylmethane skeleton, (ii) a binder resin consisting of a polycarboxylic acid resin having unsaturated groups which is obtained by subjecting a reaction product of (a) a specific epoxy resin with (b) a monocarboxylic acid compound having an unsaturated group to a reaction with (c) a polybasic carboxylic acid anhydride, (iii) a photo- polymerization initiator and (iv) a solvent; a cured product thereof; color filters containing the cured product; display devices equipped with the color filters; and so on. The specific acid dye containing a xanthene skeleton is, for example, a dye derived from Rhodamine B by replacing the chloride anion (Cl-) with a specific fluoroalkyl-containing anion, while the specific dye containing a triarylmethane skeleton is, for example, a dye derived from Basic Blue 7 by replacing the chloride anion (Cl-) with a specific fluoroalkyl-containing anion. The specific fluoroalkyl-containing anion is a tris(trifluoromethane- sulfonyl)methide anion, a bis(trifluoromethanesulfonyl)imide anion, a trifluoromethanesulfonate anion, or the like. The resin composition has clear color-purity characteristics, exhibits good patternability with little residue, and provides color filters which exhibit excellent light resistance, heat resistance and solvent resistance, and so on.

La présente invention concerne : une composition de résine colorée pour des filtres colorés qui comprend (i) une matière colorante consistant en un colorant acide spécifique contenant un squelette de xanthène ou un colorant spécifique contenant un squelette de triarylméthane, (ii) une résine liante consistant en une résine d'acide polycarboxylique ayant des groupes insaturés que l'on obtient en soumettant un produit de réaction de (a) une résine époxy spécifique avec (b) un composé acide monocarboxylique ayant un groupe insaturé à une réaction avec (c) un anhydride d'acide carboxylique polybasique, (iii) un initiateur de photopolymérisation et (iv) un solvant ; un produit durci de celle-ci ; des filtres colorés contenant le produit durci ; des dispositifs d'affichage équipés des filtres colorés ; etc. Le colorant acide spécifique contenant un squelette de xanthène est, par exemple, un colorant dérivé de la Rhodamine B par le remplacement de l'anion chlorure (Cl-) par un anion à teneur en fluoroalkyle spécifique, tandis que le colorant spécifique contenant un squelette de triarylméthane est, par exemple, un colorant dérivé du Bleu Basique 7 par le remplacement de l'anion chlorure (Cl-) par un anion à teneur en fluoroalkyle spécifique. L'anion à teneur en fluoroalkyle spécifique est un anion tris(trifluorométhane-sulfonyl)méthide, un anion bis(trifluorométhanesulfonyl)imide, un anion trifluorométhanesulfonate, ou similaires. La composition de résine a des caractéristiques de couleur claire-pureté, montre une bonne aptitude à la formation de motif avec peu de résidu, et fournit des filtres colorés qui présentent d'excellentes résistance à la lumière, résistance à la chaleur et résistance aux solvants, etc.
