    摘要: An ink composition having a suitably-adjusted hue and causing no decomposition of dyes during storage is provided. The ink composition contains a compound (a) represented by the following formula (1), an ingredient (c) and moisture-retentive agents, characterized by being from 0.1 mass % to lower than 7.0 mass % in content of the compound represented by the formula (1), 10.0 mass % or lower in content of a moisture-retentive agent having 3 or more hydroxyl groups (b) and lower than 30.0 in molar ratio of the moisture-retentive agent having 3 or more hydroxyl groups to the compound represented by the formula (1): wherein each of Ar1 and Ar2 preferably represents an aromatic heterocyclic group, each of A1 and A2 represents a hydrogen atom or a substituent, Y represents —OM or —NR1R2, M represents a hydrogen atom or a metal ion and each of R1 and R2 represents a hydrogen atom, an alkyl group, an aryl group, a heterocyclic group or the like. The ingredient (c) is at least one compound selected from C.I. Direct Yellow 59, id. 86, id. 132 or the like.
