Ink-jet recording method and apparatus using a light-tonable recording liquid

摘要

An ink-jet recording method employs a light-tonable recording liquid capable of being toned by light radiation, the liquid preferably containing a recording agent having an absorption peak within a certain wavelength range, an ammonium salt of an organic boron, and a liquid medium. The hue or the density of a desired portion of the light-tonable recording liquid on a recording member is changed by radiating toning light onto that portion. The recording member may have colored portions of an image previously recorded with a light-tonable recording liquid or colored portions just formed in the current recording. Toning light is radiated onto a desired position of the recording region of the member while varying the intensity and/or the period of light radiation in accordance with an information signal. Thus, toning may provide various half-tones or may render the toned portion of the recording liquid colorless, thereby erasing the relevant colored portions. Selective erasure may be followed by re-recording on the same position of the recording region, thereby effecting correction. All-surface erasure allows the recording member to be reused.
