Abstract
Abstract PURPOSE:To provide an all-purpose ink eraser composition (for both water and oil-based inks) which can form a coating film having excellent flexibility, by blending a thermoplastic styrene elastomer, a chlorinated hydrocarbon solvent and titanium oxide. CONSTITUTION:A thermoplastic styrene elastomer such as a three-block copolymer having a polystyrene/polybutadiene/polystyrene structure (e.g., Cariflex TR-1101, a product of Asahi Kasei Kogyo K.K.), a chlorinated hydrocarbon solvent such as 1,1,1-trichloroethane and titanium oxide are crushed by using a ball mill to disperse them in one another, thus obtaining an ink eraser.
