To provide a colorant composition having excellent thermal stability and light resistance even in the presence of a protic polar solvent.SOLUTION: A colorant composition contains a compound represented by general formula (1) and a compound having a proton dissociation energy in an alcohol of 300.0 kcal/mol or more and 335.0 kcal/mol or less. [In general formula (1), A is a carbonyl group or a sulfonyl group, R1 and R2 independently represent a C1-12 linear alkyl group or the like, R4 is H, an alkyl group, an aryl group or the like, R5 and R6 independently represent H, an unsubstituted alkyl group or the like, and R5 and R6 may bond together to form a ring structure.]SELECTED DRAWING: None 【課題】プロトン性極性溶媒存在下でも熱安定性かつ耐光性に優れた色材組成物を提供すること。【解決手段】一般式（１）で表される化合物とアルコール中のプロトン解離エネルギーが３００．０ｋｃａｌ／ｍｏｌ以上３３５．０ｋｃａｌ／ｍｏｌ以下の範囲にある化合物とを含有する色材組成物を用いる。TIFF2023048116000016.tif4074［一般式（１）中、Ａはカルボニル基またはスルホニル基を表し、Ｒ1及びＲ2は、各々独立して、炭素数１以上１２以下の直鎖状のアルキル基等を表し、Ｒ4は、Ｈ、アルキル基、アリール基等を表し、Ｒ5及びＲ6は、各々独立してＨ、無置換のアルキル基等を表し、Ｒ5及びＲ6が互いに結合して形成された環構造であっても良い。］【選択図】なし
