PURPOSE:To decrease texture blushing and to enhance color development density and shelf life by dispersing a specified developing compound and a specified color developing compound which reacts with the same under the heat-sensitive conditions to generate color development into a vehicle constituted of an organic solvent and a high-molecular compound as a main body. CONSTITUTION:A thermal color developing compound is obtained by dispersing a developing compound and a color developing compound which reacts with the same under the heat-sensitive conditions to generate color development into a vehicle constituted of an organic solvent and a high-molecular compound as a main body. In the case, 2-(o-fluoroanilino)-6-diethylaminofluoran is incorporated as the color development compound. Further 4,4'-sulfonyl-bis(2-allylphenol) is incorporated as the developing compound and furthermore 4-benzyloxy-4'-(2- methylglycidyloxy) diphenylsulfone is incorporated. Thermal recording material. is constituted by coating a supporting body with the thermal color developing composition. |
