摘要： Ink in an ink ribbon contains per 100 parts by weight of ink, 0.1-10 parts by weight of an adsorption-type corrosion suppressor. The adsorption-type corrosion suppressor may be one or more of, the following compounds: amines of the formula R--NH.sub.2, RR'--NH, RR'R"--N (where R, R' and RR" are alkyl groups), thiourea and its derivatives, benzotriazole and its derivatives, thiazole, thioamides and thiosemicarbazide. In another aspect of the invention, the ink contains an organic pigment as coloring material, said ink containing 5.0-10.0 parts by weight of graphite per 100 parts by weight of ink.
