NANOCAPSULE COMPOSITION FOR THERMOSENSITIVE REWRITABLE RECORDING MEDIUM, METHOD FOR MANUFACTURING THE SAME, AND TONER COMPOSITION FOR THERMOSENSITIVE REWRITABLE RECORDING MEDIUM USING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a nanocapsule composition for a thermosensitive rewritable recording medium, a method for manufacturing the same and a toner composition for a thermosensitive rewritable recording medium by using the same.

SOLUTION: The nanocapsule composition for a thermosensitive rewritable recording medium has such characteristics that: the composition is a core/shell type capsule composition having a dye surrounded by a polymer; the size of the capsule is extremely minimized from a conventional micrometer size to a nanometer size; the composition has excellent recording characteristics, thermal stability and is suitable for high resolution electrostatic image toner, paper, film or the like; and further, when a recording medium of paper or a OHP film on which the capsule composition is recorded is heated at high temperature, the recorded part is erased and the recording medium can be reused. The method for manufacturing the nanocapsule composition and the toner composition for a thermosensitive rewritable medium are also presented.
