Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a pigment composition excellent in coloring power, weather resistance, dispersibility, dispersion stability and temporal stability.SOLUTION: The pigment composition contains an azo pigment represented by formula (1) and a colorant having a specific structure or an additive having a specific structure. In the formula, Rdenotes an amino, aliphatic oxy, aliphatic, aryl or heterocyclic group; Rdenotes a substituent; Rdenotes a substituent; Rdenotes a hydrogen atom or a substituent; and Z denotes an electrophilic group having a Hammett p value of ≥0.2; and m denotes an integer of 0 to 5, and n denotes an integer of 1 to 4; and in the case of n=2 to 4, the formula (1) denotes a di- to tetra-mer through R, R, R, Ror Z; and the formula (1) never has an ionic hydrophilic group.
