摘要： A recording apparatus for recording data in a thermosensitive recording medium. The recording medium has a reversible thermosensitive recording material capable of selectively assuming one of two visible states, e.g., a cloudy state and a transparent state or a colored state and a decolored state when heated. The thermosensitive material is applied to a sheet of resin. The apparatus surely erases data written in the medium with no regard to the time elapsed and the number of times that data has been repetitively written. The cloud density or the color density is prevented from changing with no regard to the storage temperature, the time elapsed, or the number of times of writing, thereby preventing image quality from being degraded. In addition, the medium has a long service life.

摘要： A reversible thermosensitive recording material is composed of a support, and a reversible thermosensitive recording layer formed thereon, having a reversible temperature-dependent transparency, which contains a matrix resin and an organic low-molecular-weight material. The organic low-molecular-weight material is in the form of particles, and substantially covered by the matrix resin, and the content thereof in the reversible thermosensitive recording layer is increased from the surface side thereof toward the support side. This reversible thermosensitive recording material can be prepared by a method of coating a solution or dispersion of the matrix resin and the organic low-molecular-weight material on the support, which are dissolved or dispersed in a mixed solvent composed of at least two solvents, each having a different vapor pressure, and drying the solution or dispersion.
