<p>PURPOSE:To obtain an ink for image recording which can give an image with improved sharpness by incorporating two or more specific substances into the ink which has such a property that it adheres to only one of a pair of electrodes being in contact therewith when a voltage is applied from these electrodes. CONSTITUTION:At least fine particles (e.g. octahedral synthetic smectite) a liquid dispersion medium (e.g. glycerine or water) and a dispersant (e.g. sodium tripolyphophate) are incorporated in an ink which has such a property that it adheres to only one of a pair of electrodes being an contact therewith when a voltage is applied from these electrode.</p> |
