The object of the present invention is to provide an inkjet recording ink
ensuring excellent ejection stability even after aging of the ink and
also exhibiting excellent weather resistance; provide an inkjet recording
ink ensuring less blurring of the image drawn, in addition to excellent
ejection stability and weather resistance; and provide a yellow ink and a
dark yellow ink, which can contribute to realization of a pictorial
quality with excellent color balance as a constituent ink of an ink set.
These objects of the present invention can be achieved by an inkjet
recording ink including an aqueous medium containing a yellow dye,
particularly, a yellow dye represented by formula (1), having spectral
absorption characteristics such that the maximum absorption wavelength is
in the region from 390 to 470 nm and the absorption long-wave end has a
tailing of a specified value or less, and antioxidative characteristics
such that the ozone enforced discoloration rate constant is 5.0 x
10.sup.-2 [hour.sup.-1] or less. Furthermore, when the ink contains a
diamino compound represented by formula (A), a carbonyl group (or sulfo
group or the like)-containing cyclic compound represented by formula (B)
and an organic solvent having a specific structure, the effect of the
present invention is enhanced.
