description Aqueous ink for ink jet recording comprising a coloring matter and an aqueous medium, in which at least one of dyes represented by the formula (A) or a salt thereof is contained as the coloring matterwherein R1 and R3, independently from each other, represent a hydrogen atom, an optionally substituted alkyl group, an optionally substituted alkoxy group, an amino group, a hydroxyl group or a halogen atom, R2 and R4, independently from each other, represent a hydrogen atom, an optionally substituted alkyl group, an optionally substituted aryl group or an aralkyl group, A represents an optionally substituted phenyl group or naphthyl group, X represents a divalent bonding group free from a saturated carbon ring, and m and n, independently from each other, represent an integer of 1 to 4.
