ABSTRACT:
A pen which comprises a non-aqueous ink, the ink providing excellent cap-off performance in that the writing performance of the pen does not deteriorate even when the pen is allowed to stand exposed to air. The ink also provides a smooth feel when the pen is used for writing, and does not blob. This ink comprises an organic solvent having a vapor pressure of 0.2 mmHg (20.degree. C.) or less, a colorant and a coagulant and has a non-Newtonian viscosity index of 0.2 to 0.5 and a viscosity of 200 mPa.multidot.s (25.degree. C., 50 rpm) or less. Furthermore, the ink is characterized by containing a autolyophobic vehicle in which a contact angle to the surface of a material such as stainless steel or bronze having a high surface free energy is in the range of 5.degree. to 40.degree..
