摘要： An ink composition for a marking pen is disclosed which permits smooth writing even after a long period of standing of the pen with no cap. The ink composition comprises an organic solvent, a pigment, a resin and at least one additive selected from the group consisting of a glyceride of specified structure, and an alkylamide alcohol of specified structure and a sorbitan fatty acid ester.An erasable ink composition for writing on a writing surface such as one of resin is also disclosed, which further includes, in addition to the above, a separating agent which is a non-volatile or only slightly volatile liquid or semi-solid at normal temperatures and has a lower vapor pressure than the solvent, and is soluble in the solvent.
