<p><P>PROBLEM TO BE SOLVED: To provide an intaglio ink composition excellent in adhesion to both a substrate in which permeation of ink composition is not expected, such as plastics and a substrate in which the permeation of the ink composition is expected. <P>SOLUTION: The ink composition for intaglio printing at least includes an ultraviolet-curable composition, an oxidation-polymerizable composition, a photopolymerization initiator, an oxidative polymerization catalyst, and a polymerization inhibitor, wherein the blending ratio of the ultraviolet-curable composition to the oxidation-polymerizable composition is 92.5:7.5 to 85:15. The test result of the adhesive properties by JIS K-5600 is in the range of 0-1, that is, the rate of misalignment of print image lines is 5% or less. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
