    Abstract: Disclosed is a cyan ink used for an ink set comprising four kinds of aqueous inks, namely a cyan, magenta, yellow and black ink, respectively containing water, a water-insoluble colorant and a plurality of water-soluble organic solvents including a good solvent and poor solvent for the water-insoluble colorant. The cyan ink is characterized in that the ratio B1/A1 between the poor solvent and the good solvent in the cyan ink is within a specific range; the water-soluble solvent having the largest Ka value among the water-soluble organic solvents is a poor solvent; and the ratio B/A between the poor solvent and the good solvent contained in an arbitrary aqueous ink other than the cyan ink in the ink set and the above-described ratio B1/A1 satisfy a certain relation. Such a cyan ink has a sufficiently large area factor even with a small amount of ink droplet, and enables to obtain an image having high image density. This cyan ink is also excellent in shelf life stability and bronzing resistance.

    Abstract: An ink having a sufficiently large area factor even with a small amount of ink droplet and being excellent in shelf life stability is disclosed which enables to obtain an image having excellent image density. Specifically disclosed is a cyan ink used for an ink set comprising four kinds of aqueous inks, namely a cyan ink, a magenta ink, an yellow ink and a black ink, respectively containing at least water, a water-insoluble colorant and a plurality of water-soluble organic solvents including a good solvent for the water-insoluble colorant and a poor solvent for the water-insoluble colorant. The cyan ink is characterized in that the total amount A1 (% by mass) of the good solvent contained in the cyan ink and the total amount B1 (% by mass) of the poor solvent contained in the cyan ink are in a ratio B1/A1 of not less than 0.5 and not more than 3.0; and the water-soluble solvent having the largest Ka value determined by the Bristow method among the water-soluble organic solvents is a poor solvent.
