    摘要: A reversible thermosensitive recording material composed of a support, and a reversible thermosensitive recording layer formed on the support, containing a matrix resin and an organic low-molecular-weight material, the organic low-molecular-weight material being dispersed in the form of discrete domains in the matrix resin, thereby constituting a phase-separation structure, with the periodic distance of the phase-separation structure of the reversible thermosensitive recording layer being 1.3 .mu.m or less. This reversible thermosensitive recording material can be produced by applying a coating liquid containing the organic low-molecular-weight material and the matrix resin which are dissolved in a solvent to the support to form the reversible thermosensitive recording layer on the support; and drying the applied coating liquid under such conditions controlled so as to obtain a 1.3 .mu.m or less periodic distance of the phase-separation structure of the reversible thermosensitive recording layer, while measuring the scattering angle of a light transmitted through the reversible thermosensitive recording layer by the light-scattering method.

    摘要: A method for use in two-components electrostatic image developers is disclosed, in which secure separation of a carrier coating resinous materials from a core magnetic material is achieved without affecting the properties of the core materials through process steps benign to the environment in super- or sub-critical water compositions under the conditions of a temperature of 300° C. or more and a pressure of 20 MPa. The core magnetic material is subsequently recycled for forming carrier. This method may also be useful for processing waste including magnetic materials with silicone resin coating.
