<p>PURPOSE:To form an ink compsn. for use in ink jet recording, which can form a printed image which has a high density and excellent resistance to water and light and is of good quality, by emulsion-dispersing an org. solvent contg. an oil-soluble dye dissolved therein in a medium mainly composed of water. CONSTITUTION:A compsn. is formed by finely dispersing an org. solvent contg. an oil-soluble dye dissolved therein in a medium mainly composed of water. As the org. solvent, those having a specific gravity of 0.9-1.1 at room temp. and a solubility of less than 1wt% in water at room temp. are preferred. The term 'medium mainly composed of water' as used herein refers to water or a mixture of water with a small amount of a water-miscible org. solvent contg. optionally, additives such as a surfactant, a wetting agent, a stabilizer, etc.</p> |
