PROBLEM TO BE SOLVED: To provide an ink-erasing liquid that causes no sedimentation of the pigment, even in the case where the erasing liquid is allowed to stand for a long period of time in no need of stirring pieces in a liquid coating vessel filled with the erasing liquid. SOLUTION: The ink-erasing liquid comprising pigment, an organic solvent, a film-forming resin and, when necessary, other additives is combined with a gelling agent to gelatinize the liquid and the viscosity is increased to >=100 cps. As a gelling agent, are cited anhydrous silica, hydrogenated castor oil waxes, organic bentonite, polyamide wax and the like. In a preferred embodiment, the amount of the gelling agent to be added is >=0.1% based on the whole amount of the ink-erasing liquid.
