摘要

PROBLEM TO BE SOLVED: To provide an erasable ink composition capable of easily erasing handwriting with an eraser and exerting excellent fixing properties. SOLUTION: The erasable ink composition comprises colored and/or non- colored flake-like particles, pressure-sensitive adhesive resins, thixotropic agents and solvent. The flake-like particles have an average particle diameter of 2μm or more; the pressure-sensitive adhesive resins have an minimum film- forming temperature(MFT) of 40 deg.C or lower or a glass transition temperature (Tg) of 40 deg.C or lower; and the pressure-sensitive adhesive resins have an average particle diameter of 10μm or less.
