ABSTRACT:
Ink for use in an ink-jet color recording apparatus and a plurality of kinds of small microcapsules dispersed in the solvent, each small microcapsule having an outer shell destroyable with ultrasonic waves of a predetermined resonant frequency, each small microcapsule containing a color former within its outer shell with the outer surface of the outer shell covered with a developer. The plurality of kinds of small microcapsules are destroyed selectively with the corresponding predetermined stimuli to thereby produce magenta, cyan, yellow or black. The ink is colorless before producing the color. The ink-jet color recording apparatus irradiates the plurality of small microcapsules with ultrasonic waves of a selected frequency corresponding to a desired color to thereby change the color of the ink on a path through which the ink is fed from a color ink feeding device to an ink cartridge.
