An aqueous organic pigment dispersion contains a green copper phthalocyanine pigment and an azo-coupled -ketoamide pigment. It also includes an organic pigment dispersant at 40 weight % to 100 weight %, based on the sum of the weights of the organic pigments. This aqueous organic pigment dispersion can be combined with a humectant to provide an aqueous green inkjet ink composition. The weight ratio of the green copper phthalocyanine pigment to the azo-coupled -ketoamide pigment is from 1:1 to 10:1. The median particle diameter of each of the green copper phthalocyanine pigment and the azo-coupled -ketoamide pigment is less than 85 nm. At least 95% of the total particles of each of the green copper phthalocyanine pigment and the azo-coupled -ketoamide pigment have a particle diameter of less than 150 nm. The aqueous green inkjet ink compositions can be used in various inkjet printing methods.

The azomethine compound provided by this case is a compound showing high chroma and having excellent light resistance.
