Abstract

The invention provides a thermochromic composition which little suffers from residual color in the faded state and exhibits relatively large color difference on color change; and a process for production of the same. The invention relates to a thermochromic composition comprising an electron-donating color-developing organic compound, an electron-accepting compound and a desensitizer which is characterized in that the desensitizer is (1) a fatty acid methyl ester having 5 or more carbon atoms in total and/or (2) a fatty acid amide having 4 or more carbon atoms in total. A thermochromic composition having a desired color-temperature hysteresis can be produced by changing the blending ratio between the desensitizers (1) and (2) in incorporating both with the other components.
