<p><P>PROBLEM TO BE SOLVED: To provide gravure printing ink in which, even when a general-purpose phthalocyanine pigment or azo lake pigment is used, it can easily be dispersed and which is excellent in gloss, transparency, color developing property and storage stability. <P>SOLUTION: In the gravure printing ink, a modified pigment (D) having on a pigment (A) surface a polymer (P) obtained by polymerizing a polymer (B) which is soluble in a nonaqueous solvent and at least one polymerizable unsaturated monomer (C) which is soluble in a nonaqueous solvent and becomes insoluble or slightly soluble after polymerization is dispersed as a colorant in a vehicle. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
