Abstract: PURPOSE: To provide a gravure ink composition excellent in flowability, stability with time, printing aptitude, and gloss of printed matter. CONSTITUTION: This monoazo lake pigment composition is obtained by coupling a diazo component obtained by diazotizing an aromatic amine having a soluble group with a coupler component, followed by laking, or performing the coupling and laking at the same time. The laking reaction is performed in the presence of a water-soluble acrylic polymer in an amount of 0.1-40 pts.wt. per 100 pts.wt. of the coupler component. Alternatively, a water-soluble acrylic polymer in an amount of 0.1-30 pts.wt. is further added to 100 pts.wt. (solid component) of the aqueous slurry after the laking, to form a surface-treated pigment composition, or a powder of a water-soluble acrylic polymer in an amount of 0.1-30 pts.wt. is further added and mixed to 100 pts.wt. of the pigment obtained by filtering and drying the aqueous slurry after the laking, to form a pigment composition. The gravure ink comprises one of the pigment compositions and a gravure ink vehicle.
