| description | To provide: xanthene dye having the maximum absorbance wavelength of the ultraviolet visible absorption spectrum of a solution on the side of a longer wavelength of 560 nm or more and excellent in color characteristics (a color gamut, brightness and a contrast ratio, etc.) and heat resistance; a coloring composition including the same; color filter including the coloring composition.SOLUTION: The xanthene dye is represented by the following general formula (1). [where, R1-R4 independently represent an alkyl group, etc.; R1 and R2 or R3 and R4 may combine with each other through a single bond and a double bond, etc. to form a ring; R5 and R6 independently represent -H and a halogen atom, etc.; X represents -O-, etc.; Q represents a heterocyclic group; An represents an anion; a represents an integer of 1-3; b represents an integer of 0-3, but a general formula (1) is charge-neutral as a whole.]SELECTED DRAWING: None
【課題】溶液の紫外可視吸収スペクトルの極大吸収波長が５６０ｎｍ以上の長波長側にあり、色特性（色域、輝度、コントラスト比など）や耐熱性に優れたキサンテン系色素、該化合物を含有する着色組成物、該着色組成物を含有するカラーフィルターを提供する。【解決手段】下記一般式（１）で表されるキサンテン系色素。［式中、Ｒ１〜Ｒ４は、それぞれ独立に、アルキル基などを表し、Ｒ１とＲ２、またはＲ３とＲ４は、単結合、二重結合などを介して、互いに結合して環を形成していてもよい。Ｒ５およびＲ６は、それぞれ独立に、-Ｈ、ハロゲン原子などを表す。Ｘは-Ｏ-などを表す。Ｑは複素環基を表す。Ａｎはアニオンを表し、ａは１〜３の整数を表し、ｂは０〜３の整数を表す。ただし、一般式（１）は全体として電荷的に中性であるものとする。］【選択図】なし |
