Abstract

PURPOSE: To provide a white-board marking ink composition which is not easily dried up and is excellent in writing and erasing property by using together a specific releasing agent and α-olefin in an ink composition.
CONSTITUTION: The above ink composition is formed by mixing the following materials at 40W60°C: 40W90wt% of organic solvent (A) such as methyl ethyl ketone, benzene; 1W10wt% of coloring agent (B) which is not dissolved into (A); 2W25wt% of releasing agent (C) which is selected from higher aliphatic acid ester, glycol, fluid paraffin, etc, and is soluble in (A), having a vapor pressure higher than that of (A) and thus difficult or impossible to evaporate, and is liquid at 0W 40°C; 0.5W20wt% of resin such as polyvinyl butyral or ethylcellulose, which is soluble in (A) and a mixed solvent of (A) and (C), but is difficulty soluble or insoluble in (C); and 0.5W20wt% of 22-36C α-olefin having a melting temperature of 30W80°C.
