摘要：
There is provided a method for producing a pigment composition which contains a polymer-treated pigment (D) containing an azo lake pigment (A) and an aqueous polymer (C) precipitated with a polyvalent metal salt (B) and also contains a polymer (F) obtained by polymerizing a polymerizable unsaturated monomer (E) in the presence of the polymer-treated pigment (D). The method includes: synthesizing an azo dye by coupling a coupler component with a diazo component obtained by diazotizing an aromatic amine; and preparing the polymer-treated pigment (D). The method also includes producing the polymer (F) by polymerizing the polymerizable unsaturated monomer (E) in the presence of the polymer-treated pigment (D) to coat the polymer-treated pigment (D) with the polymer (F).
