摘要： Provided is an aqueous ink with high storage stability and scratch resistance at such a high level that the coloring material of an image is not scraped off even when lightly touched with a sharp product. The aqueous ink includes a water-insoluble coloring material and plural polymers. The plural polymers include a polymer A which relatively contributes to dispersion of the water-insoluble coloring material and a polymer B which does not relatively contribute to the dispersion of the water-insoluble coloring material compared to the polymer A. The polymer A includes a block copolymer having an acid value of 120 mgKOH/g to 180 mgKOH/g and having an ethylene oxide group as a nonionic group. The polymer B has an acid value of 150 mgKOH/g or less and a hydrogen bond parameter (δh) of the polymer obtained by solubility parameters of monomers constituting the polymer of 1.0 cal0.5/cm1.5 or more and 3.2 cal0.5/cm1.5 or less.
