ABSTRACT:
An object of the present invention is to provide an inkjet recording ink ensuring (1) excellent weather resistance (image preservability), (2) less blurring of image drawn and (3) high ejection stability. This object of the present invention can be attained by an inkjet recording ink, including an aqueous medium having dissolved therein at least two water soluble coloring materials sharing one spectral absorption region selected from a region of 500 to 580 nm and a region of 580 to 600 nm as the main absorption region in the aqueous medium.
