    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: A triboelectrically chargeable composition for use in development of electrostatic latent images. The composition contains an organotin oxide represented by the formula: ##STR1## wherein R.sup.1 and R.sup.2 are the same or different groups selected from cycloalkyl groups, substituted cycloalkyl groups, aralkyl groups and substituted aralkyl groups. The composition is embodied typically as a positively chargeable toner and also as a charge-imparting material for charging a toner.

    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.
