摘要： An aqueous marking ink composition that contains at least 1 to 20% by mass of a resin which is water-soluble and has a hydrophobic part in a molecule thereof, a colorant containing at least 5 to 30% by mass of titanium oxide, 0.05 to 2% by mass of at least one selected from acetylene glycols, acetylene alcohols or derivatives thereof, 1 to 20% by mass of a water-soluble solvent having a vapor pressure of 5 mmHg or less at 25° C. and water. The composition can provide good wetting property to a non-absorbing surface of metals, resins and the like stained with oils, can write smoothly thereon at a low viscosity without being repelled to make it possible to obtain drawn lines having a high masking property and a high fixing property, and is readily redispersed by a simple stirring operation.
