摘要： A water base erasable ink composition for use in marking pens which comprises: (a) water as a solvent; (b) a coloring agent; (c) an aqueous emulsion of at least one nonvolatile oily material which is liquid at room temperatures and is selected from the group consisting of aliphatic carboxylic acid esters, higher hydrocarbons and higher alcohols in a dry amount of 1-50% by weight; (d) a cyclodextrin or its derivative in an amount of 0.1-20% by weight; and(e) a resin which is film-forming at room temperatures. The ink composition has improved storability over a long period of time.
