ABSTRACT:
Color recording liquid which comprises, in combination, (a) an aqueous, black-colored recording liquid and (b) at least one aqueous, colored recording liquid which has other hue than black, in which said liquid (b), when applied to a recording medium, can be fixed in said recording medium within a shorter time than the time required when said liquid (a) is fixed in the same recording medium, and either or both of said liquid (a) and said liquid (b) are a recording liquid which comprises water having dispersed therein a coloring material consisting of particles of colored, ionic group-containing resin. Using the color recording liquid, it becomes possible to obtain high quality black recording without causing blurring of color, along with high quality color recording having no bleeding of color in a borderline between two adjacent color recording areas of different hues.
