Reversible thermosensitive recording medium, label and member, and, image processing apparatus and method

摘要

The reversible thermosensitive recording medium according to the present invention comprises a support, a thermosensitive layer and a protective layer in order, the thermosensitive layer comprises an electron-donating coloring compound and an electron-accepting compound and reversibly changes the color depending on temperatures, and the protective layer comprises a reactive heterocyclic compound, and inorganic fine particles of which surface is at least partially treated into hydrophobic, alternatively the protective layer comprises inorganic fine particles of which number-average particle size is 100 nm or less and of which surface is at least partially coated with organic silane compounds.
