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.

Abstract: PURPOSE: A pigment yellow 74 and printing ink composition with good transparency and density is provided. CONSTITUTION: The pigment yellow 74 is characterized in that it is obtained by coupling a coupler component comprising 2-methoxyaceto acetoanilide with a diazo component prepared by diazotizing 2-methoxy-4-nitroaniline and an aniline derivative represented by formula 2 in an amount of 0.1 to 10 mol.% based on the 2-methoxy-4-nitroaniline, in the formula 2, where Z's are the same or different and are each CONR1R2, SO2NR1R2, CONH(CH2)kNR1R2, SO2NH(CH2)kNR1R2 (wherein R1 and R2 are each independently H or an alkyl, or is combined together to form a cyclic structure; and (k) is an integer of 1 to 4), COOH or SO3H; s is an integer of 1 or 2; Q's are the same or different and are each R3, OR3 (wherein R3 is H or an alkyl), or NO2; and t is an integer of 0 to 2.
