Title (EN) PIGMENT
(FR) PIGMENT
(JA) 顔料
Abstract: front page image
(EN)This invention provides a novel pigment, which is used, for example, in color image display devices and can form a blue pixel capable of providing a high level of bright saturation, particularly a refined pigment, which has bright hue and is excellent in pigment properties such as lightfastness, solvent resistance and heat resistance, and a process for producing the same, a pigment dispersion using the pigment, and an ink for a color filter. The novel pigment is a subphthalocyanine pigment that is prepared by converting subphthalocyanine represented by general formula (1), in which X represents a halogen atom, to a pigment, has diffraction peaks at least at diffraction angles (2&thetas;)7.0°, 12.3°, 20.4° and 23.4° in X-ray diffraction and an average particle diameter of 120 to 20 nm.
(FR)Cette invention a pour objet un nouveau pigment utilisé, par exemple, dans les dispositifs d’affichage d’image en couleur, pouvant former un pixel bleu susceptible de fournir un haut niveau de saturation brillante, un pigment particulièrement raffiné dont la teinte éclatante et dont les propriétés de pigmentation sont excellentes, telles que sa solidité à la lumière, sa résistance aux solvants, sa résistance à la chaleur, ainsi qu’un processus de production de ce pigment, une dispersion de pigment utilisant ce pigment, et une encre pour filtre coloré. Ce nouveau pigment est un pigment préparé par conversion de sous-phthalocyanine, représentée par une formule (1), dans laquelle X représente un atome d’halogène, en un pigment, et possède des pics de diffraction dont les angles de diffraction minimaux sont de (2&thetas;) 7,0°, 12,3°, 20,4° et 23,4° en termes de diffraction à rayons , et dont le diamètre de particule moyen est compris entre 120 et 20 nm.
(JA) 本発明は、カラー画像表示装置などに用いられ、高水準の明彩度性を与える青色画素形成のための新規な顔料、特に冴えのある色相を有し、かつ耐光性、耐溶剤性および耐熱性などの顔料物性に優れた微細化顔料およびその製造方法、該顔料を用いた顔料分散体およびカラーフィルター用インキを提供することができる、下記一般式(1)で示され、Xがハロゲン原子であるサブフタロシアニンを顔料化してなり、少なくともX線回折における回折角(2θ)7.0°、12.3°、20.4°および23.4°に回折ピークを示し、平均粒子径が120~20nmであることを特徴とするサブフタロシアニン顔料である。
