Zusammenfassung:	The present invention relates to a composite pigment comprising: a pigment derivative including at least one sulfonyl chloride group in a basic skeleton structure of 3,6-diarylpyrrolo [3,4-c] pyrrole-1,4(2H,5H); pigment Red 291; pigment Red 177; and a complex of chemical formula 1. The composite pigment according to the present invention has excellent color characteristics while durability is not deteriorated when applied to a color filter. 본 발명은 3,6-디아릴피롤로[3,4-c]피롤-1,4(2H,5H)-다이온의 기본 골격구조에 적어도 하나 이상의 염화술포닐기를 포함하는 안료 유도체; 피그먼트 레드 291; 피그먼트 레드 177; 및 하기 화학식 1의 복합체;를 포함하는 복합안료에 관한 것으로, 본 발명에 의한 복합안료는 칼라필터에 적용 시 내구성의 저하가 없으면서도 색특성이 우수한 장점이 있다.
