An ink comprises a recording agent and a liquid medium capable of dissolving or dispersing the recording agent. The ink contains a compound represented by the following Formula (I). n n n n R₁-CONH-R₂ (I) n n n nwherein R₁ represents an alkyl group or aryl group unsubstituted or substituted with a group selected from a hydroxyl group, a carboxyl group, a sulfone group, an amino group and an acetylamino group; and R₂ represents a hydrogen atom, an amide group, an aminoalkyl group, an aliphatic carboxylic acid residual group, or an aryl group unsubstituted or substituted with a group selected from a hydroxyl group, a carboxyl group, a sulfone group, an amino group and an acetylamino group; provided that R₁ represents the unsubstituted or substituted aryl group when R₂ is a hydrogen atom. The ink is suitably used in the ink-jet recording. |
