    摘要: [Problem to be Solved] The present invention is to provide a black ink composition that not only enhances print quality, and guarantees ozone fastness of a printed product printed by the inkjet recording method, but can also inhibit bronzing. Providing a black ink composition where even color under medium duty is maintained. [Solution] The invention provides a black ink composition where at least specific two types of black colorant are mixed. A black ink composition that can guarantee color hue dose to achromatic color even under medium duty conditions is provided by adding specific colorant. Color hue is more accurately adjusted by using C.I. Direct Yellow 86 together.
