<p><P>PROBLEM TO BE SOLVED: To provide a solventborne gravure printing ink composition, which is excellent in good adhesiveness, heat resistance, oil resistance, re-solubility, and storage stability over time. <P>SOLUTION: The gravure printing ink composition and a flexographic printing ink are composed mainly of a pigment, a binder resin, a metal-containing cross-linking agent, and an organic solvent. The gravure printing ink composition is characterized in that the metal-containing cross-linking agent is a reaction product obtained by reacting (1) at least one type of organic metal compounds represented by a specific structural formula, (2) at least one type of phosphoric acid esters and (3) a compound containing an atomic group represented by (-CON<) and a carboxyl group in one molecule at a mole ratio of (1):ä(2)+(3)} ranging from 1:(2n+1) to 1:3(2n+1). <P>COPYRIGHT: (C)2008,JPO&INPIT</p> |
