PURPOSE:To obtain an ink modifier capable of remarkably improving greasing resistance when added to an ink and suitable for dry lithography, by using a specific amine compound and a cobalt compound as main components. CONSTITUTION:The objective ink modifier is composed mainly of (A) an amine compound having active hydrogen in the molecule (e.g. ethylamine, stearylamine, ethylenediamine or diethylenetriamine) and (B) a cobalt compound (preferably an organic acid cobalt salt, especially cobalt naphthenate). |
