PURPOSE:To prepare an ink compsn. which enables a high density writing or marking not erasable by rubbing on a surface with a poor writability, e.g. of an adhesive tape or polyethylene film by compounding a specific solvent, a specific resin, a silicone oil, an oil-sol. dye, and a liq. fatty acid. CONSTITUTION:An ink compsn. comprising a solvent comprising an aliph. and/or alicyclic hydrocarbon (e.g. ethylcyclohexane); a resin (e.g. Tamanol 100S, an alkylphenol resin produced by Arakawa Kagaku Kogyo Co.) sol. in the solvent; a medium- and/or high viscosity silicone oil sol. in the solvent (e.g. Silicone KF 96, a product of Shin-etu Kagaku Kogyo Co.); an oil-sol. dye (e.g. Oil Orange 201, a product of Orient Kagaku Kogyo Co.); and a liq. fatty acid (e.g. oleic acid). |
