<p>PROBLEM TO BE SOLVED: To obtain an oil-base ink which can give a glossy drawn line without filming by forming an oil-base ink essentially consisting of an aliphatic alcohol having the specified or smaller number of carbon atoms, a resin and a colorant, wherein the resin is a terpenediphenyl resin essentially consisting of a terpenediphenyl resin having the specified number of phenol groups. SOLUTION: This ink is an oil-based one essentially consisting of a 4C or lower aliphatic alcohol, a resin and a colorant, wherein the resin is a terpenediphenyl resin essentially consisting of terpenediphenyl having two phenol groups. The 4C or lower aliphatic alcohol is the main solvent and is exemplified by methyl, ethyl, n-propyl, i-propyl or i-butyl alcohol. Its amount of use is desirably 40-90wt.% based on the total weight of the ink. The amount of the terpenediphenol resin used is desirably 5-30wt.% based on the total weight of the ink.</p> |
