Aqueous pigment dispersion, method for producing same, coloring composition, ink composition, ink composition for inkjet recording, and inkjet recording method

An aqueous pigment dispersion, comprising:

• at least one of an azo pigment represented by the following Formula (1) and showing characteristic X-ray diffraction peaks at least at Bragg's angles (2θ±0.2°) of 4.8°, 7.2°, 9.7°, 20.0°, 17.3°, 26.0°, and 26.7° in CuKα characteristic X-ray diffraction, and a tautomer thereof;
• a first dispersant;
• a second dispersant;
• and
• water,
• wherein the first dispersant has an amine value of 5 mg KOH/g or more, with the amine value being larger than the acid value;
• the second dispersant has an acid value of 5 mg KOH/g or more, with the acid value being larger than or equal to the amine value;
• and
• the aqueous pigment dispersion is obtained via the following Step b:
• Step b:
• a step of dispersing an azo pigment represented by Formula (1) and/or a tautomer thereof, a first dispersant, and a second dispersant in water and thereby obtaining an aqueous pigment dispersion.
