摘要： PROBLEM TO BE SOLVED: To provide a reversible dichromatic thermal recording material which ensures a sharp contrast and the formation and erasing of an image and can keep an image which is stable over time under daily life environments. SOLUTION: This reversible dichromatic thermal recording material has a reversible thermally color developing composition which uses a routinely colorless or pale-color electron-donative dye precursor and an electron-receptive compound and can relatively form a color development state and a decolorization state depending upon the difference in a heating temperature and/or a cooling temperature after heating, formed on a support. In addition, the reversible thermally color developing composition is formed of two kinds of parts showing different color development color tones from each other and in a mutually independent and discrete state. Further, the thermal recording material is characterized in that the crystallization rate of the electron-receptive compound varies at the time of the color development state and at the time of the decolorization state of the composition, when the shift from the former state to the latter state occurs.

摘要： PROBLEM TO BE SOLVED: To obtain a new compound useful as an electron acceptable substance of a heat-sensitive recording material. SOLUTION: This compound is represented by formula I (R is an aromatic group or a hetero-aromatic residue; A is difunctional connecting group; M is Mg, Zn or Ba), e.g. a compound of formula II. The compound of formula I is obtained by dropping, e.g. a primary amine compound solution (dissolved in tetrahydrofuran, etc.) which may have a substituent group into a mixture of dicarboxylic anhydride containing bifunctional connecting group (e.g. maleic anhydride) with a base (e.g. triethylamine) and a solvent under stirring and further advancing the reaction while stirring at ambient temperature, concentrating the reaction mixture under reduced pressure, adding a proper amount of an aqueous dilute hydrochloric acid solution thereto to acidify solution in the system, filtering the deposited crystals under reduced pressure and washing the resultant crystals with water and drying the crystals. A heat-sensitive recording material excellent in stability of the ground and coloring image is obtained by using the compound as the electron acceptable substance.
