<p>PURPOSE:To obtain the subject ink enabling smooth writing, giving comfortable feeling in writing without causing thinned record and dripping of the ink and storable over a long period by adding a stearic acid derivative to an ink composed of a dye, an organic solvent and a resin. CONSTITUTION:The objective ink can be produced by adding a stearic acid derivative (e.g. alpha-cyanostearic acid, thiocarbon-distearic acid and phenylsulfonylstearic acid) in an amount of preferably 0.5-5wt.% to an ink composed of a dye (e.g. mordant dye or basic dye), an organic solvent (e.g. benzyl alcohol or glycols) and a resin (e.g. ketone resin or rosin-modified resin).</p> |
