R1-CONH-R2 (I) wherein 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.
