PROBLEM TO BE SOLVED: To provide an ink for high speed printing for conducting flexographic printing at high speed with linear velocity of 1200 ft/min. (about 366 m/min.) or more.SOLUTION: There is provided an in for high speed printing containing one or a plurality of resin, one or a plurality of coloring agent, one or a plurality of solvent and one or a plurality of adhesive, having surface tension of the ink of 26 mN/m or more and of which surface tension is measured when percentage of volume fraction of the total non-volatile material of the ink to volume fraction of maximum total non-volatile material of the ink is 0.40 to 0.90. There is provided an ink for high speed printing having surface tensile of preferably 28 mN/m, more preferably 30 mN/m. There is provided an ink for high speed printing having the resin of 5 to 30 wt.% of the ink, the coloring agent of 4 to 25 wt.% of the ink and the solvent of 40 to 70 wt.% of the ink.SELECTED DRAWING: Figure 2 |
