摘要： An ink which can cause a change in its adhesiveness by an electrochemical reaction is obtained by impregnating a crosslinked substance such as polyvinyl alcohol with a liquid dispersion medium comprising an organic solvent having a relative dielectric constant of 15 or larger at 25.degree. C. such as ethylene glycol. The ink shows little characteristic change due to drying, etc., and suitably retains its fluidity when left standing in the air for a long period. The ink is supplied with a pattern of energy to be provided with an adhesive pattern, which is then transferred to a recording medium such as plain paper, directly or by the medium of an intermediate transfer medium to form an ink pattern corresponding to the energy pattern applied.

摘要： An image recording method and an image recording apparatus using an ink which is substantially non-adhesive but can be imparted with an adhesiveness when subjected to a pH change. In the image recording method, the ink is subjected to a pattern of pH change to be provided with an adhesive pattern, which is then transferred to a recording medium, such as plain paper, directly or by the medium of an intermediate transfer medium to form an ink pattern corresponding to the pH change pattern.

摘要： An image recording apparatus for recording an image on a recording medium comprises ink transporting roll for transporting a fluid ink, energy applying element for selectively applying energy to the ink transported by the ink transporting roll, transfer member for transferring to the recording medium the ink whose transfer characteristics are changed upon selectively application of the energy and coating member disposed in an upstream of the energy applying element with respect to a transporting direction of the ink transporting roll so as to oppose the ink transporting roll, for supplying the ink having a predetermined thickness to the ink transporting roll. A distance between the ink transporting roll and the coating member is gradually reduced from the upstream to a downstream.

摘要： An ink which can be imparted with an adhesiveness on application of an electric current is obtained by impregnating a crosslinked substance such as guar gum or polyvinyl alcohol compound with a liquid dispersion medium such as water. The ink is supplied with a pattern of energy to be provided with an adhesive pattern, which is then transferred to a recording medium, such as plain paper, directly or by the medium of an intermediate transfer medium to form an ink pattern corresponding to the energy pattern applied. The ink further comprises a buffer action-imparting substance and is excellent in storage stability and stability of performances during a continuous use.

摘要： A printing process using an ink which is substantially non-adhesive but can be imparted with an adhesiveness when subjected to a pH change. In the printing process, the ink is subjected to a pH change to be provided with an adhesiveness to a desired depth, and the resultant adhesive ink is supplied to a printing plate having a pattern of ink receptibility to form thereon an ink pattern corresponding to the ink receptibility pattern. The ink pattern is then transferred to a transfer-receiving medium such as plain paper to form thereon a recorded image. In the above-mentioned printing process, a uniform thin ink layer can be supplied to the printing plate by chemically regulating the amount of the ink to be supplied.

摘要： A method for transferring a viscous substance includes the steps of providing a viscous substance having an adhesive characteristic which changes in correpondence to the polarity of a voltage applied thereto. The viscous substance had an adhesive characteristic when no voltage is applied thereto and its adhesiveness is reduced when a voltage is applied thereto. The method further includes the steps of disposing the viscous substance between first and second electrodes and applying a voltage between the first and second electrodes to thereby substantially attach the entirety of the viscous substance to one of the first and second electrodes.

摘要： A toner suitable for developing electrostatic images is produced through a process comprising: dispersing a monomer composition comprising at least a polymerizable monomer and a colorant in an aqueous medium heated at a temperature higher than a polymerization temperature, thereby to form particles of the monomer composition; adjusting the aqueous medium to the polymerization temperature; and adding a substantially water-insoluble polymerization initiator to the aqueous medium containing the particles of the monomer composition dispersed therein and adjusted to the polymerization temperature, thereby to cause the polymerization of the polymerizable monomer. According to this process, a toner containing a large amount of a low-softening point compound and having good fixability at low pressure and/or low temperature can be produced while retaining good anti-blocking characteristic and fluidity.
