Abstract

PURPOSE:To obtain the title eraser with the excellent light shielding property by composing the titled eraser of a polymer which is soluble in alcohol or a hydrous alcohol, and has a good sticking property to a hydrophilic synthetic resin and an appropriate flexibility, a pigment and a solvent selected from ethanol or a mixed solvent of ethanol and water. CONSTITUTION:The polymer is exemplified by a copolymer of acrylate-maleic anhydride, a copolymer of acrylate-acrylic acid, a copolymer of acrylate- methacrylic acid, a copolymer of vinyl pyrolidone-vinyl acetate, polyvinyl pyrolidone or a copolymer of styrene-maleic anhydride. The eraser contains 5-20wt.% of the alkaline neutralizate of said polymer or the mixture of said polymers, 5-20wt.% the pigment and the solvent containing <=60wt.% water. And, said eraser contains 5-15wt.% silicic acid anhydride to improve matting effect, and 0.1-1wt.% acethylene glycol type antifoamer to prevent the generation of a pinhole, thus obtaining the good eraser.
