| abstract |
An ink composition for ink jet recording which is an oil in-water type dispersion prepared by dispersing, in an aqueous medium, a mixture of a hydrophobic dye solution and finely divided particles of vinyl polymer, wherein the vinyl polymer is essentially insoluble in water and does not swell in water but swells in solvents capable of dissolving hydrophobic dyes, said ink composition having a low viscosity, a high density and being very stable. The records obtained using this ink composition are not smeared or removed upon contact with water or perspiration. |
