  A highly bleed-alleviating ink composition including at least one colorant, an aqueous media, a linear diol, and a humectant. The main feature of the ink composition is the addition of the linear diol. When the ink composition is applied in ink-jet printing, not only is the bleeding between black ink and color ink alleviated, but also water-fastness and printing quality are improved.
