<p>PURPOSE:To provide an ink improving the separation of printed paper from an ink drum when the paper is printed, improving the winding-up of the printing paper, and preventing the generation of the back transfer of the printed ink, because the printed ink is substantially not transferred to the back surface of the next printing paper. CONSTITUTION:The ink comprises a water drop-in-oil type emulsion comprising approximately 10-60wt.% of an oil phase containing a wax component and approximately 90-40wt.% of a water phase. The content of the wax component is preferably 0.5-5wt.% based on the whole amount of the ink, and the wax component preferably has a melting point of 50-120 deg.C.</p> |
