Abstract

An aqueous black ink composition that contains a colorant represented by formula (1) and one or more colorants (B-a) to (B-t). The ink composition is stable even when stored for a long period of time, has a low chroma and tint-free neutral black-to-gray color even when printing a deep color or light color, has a high printed image density, exhibits no change in hue when printed on different media, and produces a black recorded image having particularly excellent recorded image color development properties, light resistance, ozone gas resistance and moisture resistance.
