ABSTRACT:
A rewritable thermosensitive recording medium having a recording layer, the transparency of which reversibly changes depending on the temperature thereof. Further, the recording layer contains a matrix material and an organic low-molecular-weight material dispersed in the matrix material as main components thereof. Moreover, an alicyclic dicarboxylic acid compound is added to the organic low-molecular-weight material dispersed in the matrix material. Furthermore, by adding the alicyclic dicarboxylic acid compound to the organic low-molecular-weight material, the eutectic point of the organic low-molecular-weight material and the alicyclic dicarboxylic acid compound becomes higher than the melting point of the organic low-molecular-weight material. Additionally, in spite of the fact that the amount of the alicyclic dicarboxylic acid compound to be added to the organic low-molecular-weight material is small, the difference between the eutectic point of the organic low-molecular-weight material and the alicyclic dicarboxylic acid compound and the melting point of the organic low-molecular-weight material is much larger than those obtained in cases of conventional recording materials. Consequently, the range of temperature, to which the recording layer should be heated for changing a state thereof from an opaque state to a transparent state, can be considerably enlarged without reducing the opacity of the recording layer.
