Summary:The purpose of the present invention is to improve the solubility and heat resistance of a yellow compound in an organic solvent (such as PGMEA). Provided are a coloring composition having excellent color characteristics, a colorant for a color filter, and a color filter. A compound is represented by general formula (1). In the formula (1): each Q independently represents a group represented by formula (2); n represents an integer of 2-10; L represents a group of 2-10; each of R^1 to R^9 independently represents H, a hydroxyl group, a halogen atom, an amino group, a sulfonyl group, an alkyl group, an alkenyl group, an alkoxy group, an acyl group,-O-, an aromatic hydrocarbon group, a heterocyclic group or the like, and can form a ring by bonding adjacent groups to each other; each Z independently represents a divalent group or a trivalent group, and represents an amino group, an alkylene group, a group containing-O- or a single bond; and a plurality of Qs are bonded to each other via L or Z. (과제) 황색계 화합물의 유기 용매 (PGMEA 등) 에 대한 용해성 및 내열성을 향상시키는 것. 색채 특성이 우수한 착색 조성물, 컬러 필터용 착색제 및 컬러 필터를 제공하는 것. (해결 수단) 하기 일반식 (1) 로 나타내는 화합물. TIFFpat00050.tif1852 [식 (1) 중, Q 는 각각 독립적으로 식 (2) 로 나타내는 기이고, n 은 2 ∼ 10 의 정수, L 은 2 ∼ 10 가의 기를 나타낸다. R1 ∼ R9 는 각각 독립적으로, H, 수산기, 할로겐 원자, 아미노기, 술포닐기, 알킬기, 알케닐기, 알콕시기, 아실기, -O-, 방향족 탄화수소기, 복소 고리기 등을 나타내고, 이웃하는 기끼리로 서로 결합하여 고리를 형성하고 있어도 된다. Z 는 각각 독립적으로 2 가 기 또는 3 가 기이고, 아미노기, 알킬렌기, -O- 또는 단결합을 포함하는 기를 나타내고, 복수 있는 Q 는 L 또는 Z 를 개재하여 서로 결합하고 있는 것으로 한다.] TIFFpat00051.tif4492
