<P>PROBLEM TO BE SOLVED: To easily provide a high-gloss and high-density printing ink composition which does not cause pigment shock and is excellent in storage stability by mixing a high-density aqueous pigment dispersion and a varnish composition, in an ink composition for gravure and flexographic printing. <P>SOLUTION: The printing ink composition is obtained by mixing a pigment dispersion containing a pigment, (A) an alkali-soluble styrene-acrylic resin having an acid value of 150-220, a nonionic activator, and a solvent containing water, and a varnish composition containing (B) an alkali-soluble styrene-acrylic resin having an acid value of 140-330 and (C) a styrene-acrylic emulsion having an acid value of 10-120, at a specific ratio. <P>COPYRIGHT: (C)2013,JPO&INPIT |
