PROBLEM TO BE SOLVED: To provide a thermosensitive coloring material (sheet) with superior coloring properties and preservability. SOLUTION: This thermosensitive coloring composition consists of a color developing compound, and a coloring compound and a polymer compound which form a color through a chemical reaction with the color developing compound under heat, dispersed in an organic solvent. In this case, 2-(o-fluoroanilino)-6- diethylaminofluoran or 2-(o-chloroanilino)-6-diethylaminofluoran as the coloring compound and 2,4-dihydroxy-2'-methoxybenzanilide as the color developing compound and further, Fischer-Tropsch wax and 4-benzyloxy-4'-(2- methylglycidyloxy) diphenylsulfone are contained in the thermosensitive coloring composition. This composition is applied to the surface of a support and then is dried. |
