PROBLEM TO BE SOLVED: To form a black image having the good stability of coloring density, the preservative stability of an image part and nonimage part such as an chemical resistance, and an excellent hue by using a dispersant being capable of obtain an electron acceptable compound through the simultaneous dispersion of an anthranilic acid derivative expressed by a specific formula and an anthranilic acid derivative expressed by a specific formula. SOLUTION: The thermal recording material includes as an electron acceptable compound a dispersed substance obtained by simultaneously dispersing an anthranilic acid derivative expressed by formula I and an anthranilic acid derivative expressed by formula II. In the formula, R1 shows an aryl group or an alkyl group; these groups may further include a substitutent, and as R1, there are given a 6-13C alkyl group, and a 7-9C aryl oxy-alkyl group. Furthermore, in the formula II as a group indicated by R2, it is preferable to be a 6<=C unsubstituted aryl group, a 6-9C alkyl group, or the like. Besides, an addition amount of an electron receptor compound is preferable to be 50-400 wt.% relative to an electron donative achromatic dye. |
