PROBLEM TO BE SOLVED: To provide a novel quinacridone mixture that achieves excellent storage stability of both a pigment dispersion and an ink, and is effective in achieving an ink having excellent discharge stability.SOLUTION: A quinacridone mixture comprises a quinacridone compound in the case of m=1 and n=1 in the general formula (1) and another quinacridone compound, different from one in the case of m=1 and n=1 (where R, R, Rand Rare a hydrogen atom, a halogen atom, and a C1-C4 alkyl group, and may be the same or different. Rand Rare a C1-C4 alkyl group, and may be the same or different. m and n are an integer of 0-2).SELECTED DRAWING: None 【課題】顔料分散体およびインクの良好な保存安定性を両立し、吐出安定性に優れたインクの実現にも有効な新規のキナクリドン混合物の提供を目的とする。【解決手段】下記一般式（１）において、ｍ＝１かつｎ＝１の場合のキナクリドン化合物と、ｍ＝１かつｎ＝１の場合以外のキナクリドン化合物とを含有するキナクリドン混合物。（式中、Ｒ1，Ｒ2，Ｒ3およびＲ4は水素原子、ハロゲン原子、炭素数１〜４のアルキル基を表し、同一でも異なっていてもよい。また、Ｒ5およびＲ6は炭素数１〜４のアルキル基を表し、同一でも異なっていてもよい。ｍ、ｎは０〜２の整数を表す。）【選択図】 なし
