ABSTRACT:
A waste-ink absorbent to be mounted on an ink-jet recording apparatus comprises a composition containing a biodegradable polymer and a microorganism growth nutrient. An ink contains a recording agent and a liquid medium for dissolving or dispersing the recording agent, the recording agent comprising a composition containing a biodegradable polymer linked to a solubilizing group of a water-soluble dye by coordination bonding. An ink-jet recording method conducts recording by ejecting droplets of the ink through an ejection orifice of a recording head in correspondence with recording signals. An ink-jet recording apparatus is equipped with a recording unit having an ink container holding the ink therein and a head.
