MULTI-COLOR REVERSIBLE THERMOSENSITIVE RECORDING MEDIUM CONTAINING REVERSIBLY COLOR DEVELOPING MULTI-CORE SINGLE FILM MICROCAPSULE PARTICLE

摘要

PROBLEM TO BE SOLVED: To provide highly practical multi-color reversible recording medium which can effectively reduce the texture coloration of a reversible thermosensitive recording medium and uses at least two or more kinds of reversibly color developing multi-core single film microcapsule fine particles.

SOLUTION: This multi-color reversible thermoplastic recording medium contains the reversibly color developing multi-core single film microcapsule fine particle which encapsulates in resin an electron-donative compound which can relatively form a color developing state and a color fading state according to a difference in the heating temperature and/or a cooling speed after heating. In addition, at least two or more kinds of the reversibly colorable multi-core single film microcapsules with a differing color tone, are added to a single recording layer.
