Title (EN) QUINOPHTHALONE COMPOUND
(FR) COMPOSÉ DE QUINOPHTALONE
(JA) キノフタロン化合物
Abstract:
(EN) The present invention addresses the problem of providing a novel yellow pigment having both excellent brightness and coloring power. In order to solve such a problem, the present invention provides a novel quinophthalone compound. Specifically, the above problem is solved by providing a quinophthalone compound represented by formula (1). In addition, the present invention provides a colorant containing the quinophthalone compound represented by formula (1) and a coloring composition containing the colorant. (1) (In the formula, X1 to X16 each independently represent a hydrogen atom or a halogen atom, and Z represents an alkylene group having a carbon number of 1 to 3.)
(FR) La présente invention concerne un nouveau pigment jaune présentant à la fois une excellente brillance et un excellent pouvoir colorant. Elle se réfère à un nouveau composé de quinophtalone, et spécifiquement à un composé quinophtalone représenté par la formule (1). L'invention concerne également un colorant renfermant le composé de quinophtalone représenté par la formule (1) ; et une composition colorante contenant ce colorant. (1) (Dans la formule, X1 à X16 représentent chacun indépendamment un atome d'hydrogène ou un atome d'halogène, et Z représente un groupe alkylène dont le nombre d'atomes de carbone est compris entre 1 et 3).
(JA) 優れた輝度と着色力を兼備する新規黄色顔料を提供することを課題とする。このような課題を解決するために、本発明は新規キノフタロン化合物を提供する。具体的には、下記式(1):(式(1)中、X~X16は各々独立に水素原子又はハロゲン原子であり、Zは炭素数1~3のアルキレン基である)で表されるキノフタロン化合物を提供することにより、上記課題を解決する。さらに、式(1)で表されるキノフタロン化合物を含有する着色剤、及び当該着色剤を含有する着色組成物を提供する。
