<p>PURPOSE:To provide ink for ink jet recording, which is usable regardless of the quality of the materials from which objects to be recorded are made, containing a solvent (composed of a ketone, an alcohol and water), a dye, an ionizing salt, a nonionic surfactant and a binder. CONSTITUTION:An ink contg. a solvent (A) composed mainly of a ketone, an alcohol and water, a dye (B), an ionizing salt (C), a nonionic surfactant (D) and a binder (E) is provided. As said solvent, a system composed of methanol or ethanol, cyclohexanone and water is especially preferred. A solvent composition consisting of 5-10pts.wt. water, 35-75pts.wt. ketone and 15-60pts.wt. alcohol is preferred. As said nonionic surfactants, silicone or fluorine-contg. nonionic surfactants are preferred. As the binder having excellent bond properties, vinyl butyral resin etc. are preferred.</p> |
