    摘要: Problem to be Solved:
    To provide an ink composition having high reliability in terms of clogging or the like and compatibly having all of light fastness, gas fastness and moisture resistance. Means to Solve the Problem:
    An ink composition comprising at least water, at least one member selected from a compound represented by formula (1) shown below and a salt thereof, and at least one member selected from an aromatic compound having a carboxyl group and a salt thereof:
    Formula (1):

    In formula (1), A represents a residue of a 5-membered heterocyclic diazo component A-NH 2 ; B 1 and B 2 each represents -CR 1 = or -CR 2 =, or either one of B 1 and B 2 represents a nitrogen atom and the other represents -CR 1 = or -CR 2 =; R 5 and R 6 each independently represents a hydrogen atom, an aliphatic group, an aromatic group, a heterocyclic group or the like; and G, R 1 and R 2 each independently represents a hydrogen atom, a halogen atom, an aliphatic group, an aromatic group, a heterocyclic group or the like.
