Abstract
A water-based black ink composition which, when used in inkjet recording and writing tools, can provide recorded matter that exhibits excellent color development, light fastness, resistance to ozone gas, moisture and water, and accommodation characteristics to a sensor, and excellent solubility and therefore can be stably stored in the form of a recording fluid; and an inkjet recording method and a colored body, using the same. The water-based black ink composition contains C.I. Acid Black 2 as a colorant component. The inkjet recording method uses the water-based black ink composition, while the colored body is a body colored with the water-based black ink composition.
