    • PROBLEM TO BE SOLVED: To provide a color composition giving colored printed images excellent in hue, fastness and fixability to printing materials under highly humid conditions, and to provide an ink composition for ink-jet printing use. SOLUTION: The color composition contains a coloring matter compound represented by the general formula(1) and meets the requirements 1 and 2 described below. In the general formula(1), Dye denotes a coloring matter structural moiety; Q is -SO-, -SO 2 , -SO 2 NR 11 -, -CO- or -CONR 12 -, wherein R 11 and R 12 are each H or a substituent; W is a bivalent aliphatic group; M is an ionic group; and m is an integer of ≥1. The requirement 1: 200 2 M groups in the coloring matter compound) 2 M groups in the coloring matter compound)/p>0.5, wherein Mw is the molecular weight of the coloring matter compound, and p is the total number of ionic hydrophilic groups substituted on the coloring matter compound.
