Reversible thermosensitive recording material and method for producing the same

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.
