Abstract
An ink for ink jet recording which inclides a water-insoluble ionic group-containing polymer added to a colored fine particle dispersion containing at least a hydrophobic high-boiling organic solvent having a boiling point of 150° C. or more and an oil-soluble dye. In a preferred embodiment, the water-insoluble ionic group-containing polymer is converted by emulsification dispersion into a fine particle dispersion and added to the colored fine particle dispersion, and the oil-soluble dye is represented by specific formulae.
