Title (EN) COLORANT COMPOSITION FOR A COLOR FILTER, COLOR FILTER USING THE SAME, AND LIQUID CRYSTAL DISPLAY DEVICE
(FR) COMPOSITION DE COLORANT POUR FILTRE DE COULEUR, FILTRE COLORE L'UTILISANT, ET AFFICHEUR A CRISTAUX LIQUIDES
(JA) カラーフィルタ用着色組成物、これを用いたカラーフィルタ、及び液晶表示装置
Abstract: front page image
(EN)Disclosed is a photosensitive colorant composition containing: a green colorant including at least a halogenated zinc phthalocyanine pigment; a photopolymerizable monomer; a resin; a photopolymerization initiator; and a solvent. Said photopolymerizable monomer includes: either a polyfunctional urethane acrylate (constituting 15 to 45 wt%, inclusively, of the solid part of said photosensitive colorant composition) that has at least 0.7 x 10-3 mol/g of urethane groups and at least 4.5 x 10-3 mol/g of double bond groups, and that has a (meth) acryloyl group obtained by reacting a polyfunctional isocyanate with a (meth)acrylate having a hydroxyl group; or, dipentaerythritol pentaacrylate and dipentaerythritol hexaacrylate (constituting 10 to 25 wt%, inclusively, of the solid part of said photosensitive colorant composition). Furthermore, the voltage holding ratio of a liquid crystal display element provided with the color filter obtained by using said photosensitive colorant composition is no less than 90%.
(FR)L'invention concerne une composition de colorant photosensible contenant un colorant vert comportant au moins un pigment phtalocyanine de zinc halogéné, un monomère photopolymérisable, une résine, un initiateur de photopolymérisation, et un solvant. Ledit monomère photopolymérisable comporte: un acrylate d'uréthane multifonctionnel (correspondant à 15 à 45% en poids inclus, de la partie solide de ladite composition de colorant) qui a au moins 0,7 x 10-3 mol/g de groupes d'uréthane et au moins 4,5 x 10-3 mol/g de groupes liaison double, et qui a un groupe (méth)acryloyle obtenu par réaction d'un isocyanate multifonctionnellllllll avec (méth)acrylate ayant un groupe hydroxyle; ou dipentaérythritol pentaacrylate et dipentaérythritol hexaacrylate (correspondant à 10 à 25% en poids inclus, de la partie solide de ladite compositionm de colorant photosensible). De plus, le rapport de maintien de tension d'un élément d'afficheur à cristaux liquides pourvu du filtre coloré que l'on obtient en utilisant ladite composition de colorant n'est pas inférieur à 90%.
(JA) 少なくともハロゲン化亜鉛フタロシアニン顔料を含む緑色着色剤と、光重合性モノマーと、樹脂と、光重合開始剤と、溶剤を含有してなる感光性着色組成物。該光重合性モノマーは、水酸基を有する(メタ)アクリレートに多官能イソシアネートを反応させて得られる(メタ)アクリロイル基を有する、ウレタン基数が0.7×10-3mol/g以上、二重結合基数が4.5×10-3mol/g以上の多官能ウレタンアクリレートを、該感光性着色組成物の固形分を基準として15重量%以上45重量%以下の範囲で含有するか、または、ジペンタエリスリトールペンタアクリレート及びジペンタエリスリトールヘキサアクリレートを、該感光性着色組成物の固形分を基準として10重量%以上25重量%以下の範囲で含有する。さらに、該感光性着色組成物は、該感光性着色組成物を用いて得たカラーフィルタを備える液晶表示素子の電圧保持率が90%以上である。
