Paragraph 0125; 0127, (2017/06/20)
PROBLEM TO BE SOLVED: To provide a coloring composition, an ink composition, and an ink-jet recording method using an aqueous pigment dispersion. SOLUTION: The present invention provides an aqueous pigment dispersion characterized by comprising an azo pigment which is represented by formula (1) which, in analysis by diffractometry with CuKα characteristic X-ray, shows characteristic X-ray diffraction peaks at Bragg angles (2θ±0.2°) of 7.6° and 25.6°, and a process for producing the same.

Paragraph 0135-0138, (2017/01/02)
PROBLEM TO BE SOLVED: To provide a method for producing a 5-aminopyrazole derivative at a reduced production cost and in high yields. SOLUTION: The method for producing a 5-aminopyrazole derivative or a salt thereof includes performing the following steps (a) and (b) in the order: (a) the step of deriving an intermediate by reacting a compound having a specified structure or a salt thereof with an active methylene compound having a specified structure; and (b) the step of obtaining the 5-aminopyrazole derivative or a salt thereof by reacting the intermediate with a hydrazine derivative.

Page/Page column 47, (2012/07/27)
To provide an aqueous ink for inkjet recording, which realizes excellent ink ejection properties, tinctorial strength, and image fastness using an aqueous pigment dispersion. An aqueous pigment dispersion containing A and B, wherein A is an azo pigment represented by the following formula and in a crystal form having at least one characteristic peak at Bragg angles (2θ) of 5 to 15° and 20 to 30° in. X-ray diffraction with characteristic Cu Ka line, a tautomer, a salt or hydrate thereof; and B is a vinyl polymer containing a specific structural unit, a structural unit derived from a salt-forming group-containing monomer (a), and a structural unit derived from a monomer selected from a styrene series macromer (b) and a hydrophobic monomer (c), provided that the water-insoluble vinyl polymer has at least either of 2 or more hydroxyl groups and 1 or more carboxyl groups at the end of the main chain:
