    摘要： An aqueous ink comprising at least a colorant, a water-soluble organic solvent and a compound represented by general formula (I) shown below, wherein said water-soluble organic solvent stays liquid at a temperature of not higher than 40° C., exhibits a water solubility of not lower than 1% by weight at a temperature of 20° C. and a saturated vapor pressure of not higher than 1.7 Pa at a temperature of 20° C. and is contained in an amount of from 5 to 35% by weight: wherein Y represents a nonmetallic atom group required to form a 5- to 7-membered ring with C and N; X represents a hydrogen atom, oxyradical group, hydroxyl group, alkyl group, alkenyl group, alkinyl group, aryl group, acyl group, sulfonyl group, sulfinyl group, alkoxy group, aryloxy group or acyloxy group; and R1 to R4 may be the same or different and each represent a hydrogen atom or alkyl group, with the proviso that any two of R1 to R4 and Y may be connected to each other to form a 5- to 7-membered ring.
