PURPOSE:To provide the titled composition outstanding in resistance to nib dryability, thus with nibs not apt to dry even left uncapped for a long time, comprising a colorant, organic solvent and a specific primary amine. CONSTITUTION:The objective composition comprising (A) pref. 2-17wt.% of a colorant, (B) pref. 65-85wt.% of an organic solvent (e.g. ethanol, methyl ethyl ketone, benzene, cyclohexane, hexane, ethylene glycol monoethyl ether), and (C) pref. 0.05-5wt.% of a >=16C primary amine (e.g. hexadecylamine, stearylamine). |
