<p>PURPOSE:To provide the titled composition free from dripping in writing, by adding a fluorine-containing surface active agent to an ink composition containing a colorant, an organic solvent and a resin, thereby adjusting the surface tension of the mixture at a specific level. CONSTITUTION:The objective composition is produced by adjusting the surface tension of an ink composition containing a colorant (e.g. oil-soluble dye), an organic solvent (e.g. benzyl alcohol) and a resin (e.g ketone resin) to 20-30dyne/ cm with a fluorine-containing surface active agent. The amount of the surface active agent is preferably about 0.01-1.0wt% based on the whole composition.</p> |
